Let's divide 86516941 by 729
We want to figure out the number of times 86516941 can be divided by 729.

Advancing to step 1:
When dividing 8 by 729, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 729

Moving on to step 2:
If we divide 86 by 729, we get 0 and a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Take the next digit (5) from the dividend and append it to 86, then repeat: 865 / 729

Moving on to step 3:
The number 729 fits into 865 1 times, leaving a remainder of 136.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 729 from 865 leaves us with 136.
Include the next digit (1) from the dividend after 136, then repeat: 1361 / 729

Going ahead to step 4:
When dividing 1361 by 729, we get 1 with a remainder of 632.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 632 after subtracting 729 from 1361.
Include the next digit (6) from the dividend after 632, then repeat: 6326 / 729

Advancing to step 5:
The number 729 fits into 6326 8 times, leaving a remainder of 494.
The next digit of our result is 8. 
Result so far: 118.0
If we take 5832 away from 6326, we end up with 494.
Append the next digit (9) from the dividend to 494 and continue with: 4949 / 729

Going ahead to step 6:
If we divide 4949 by 729, we get 6 and a remainder of 575.
Record the quotient 6 as the next digit in the result. 
Result so far: 1186.0
Subtract 4374 from 4949 to get 575.
Fetch the next digit (4) from the dividend, attach it to 575 and continue: 5754 / 729

Let's proceed to step 7:
729 goes into 5754 7 times with a remainder of 651.
Put 7 as the next digit of the answer. 
Result so far: 11867.0
If we take 5103 away from 5754, we end up with 651.
Append the next digit (1) from the dividend to 651 and continue with: 6511 / 729

Advancing to step 8:
The number 729 fits into 6511 8 times, leaving a remainder of 679.
Use 8 as the next digit of our solution. 
Result so far: 118678.0
The remainder is 679 after subtracting 5832 from 6511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6790, and continue the process.

Let's proceed to step 9:
The number 729 fits into 6790 9 times, leaving a remainder of 229.
Put 9 as the next digit of the answer. 
Result so far: 118678.9
Subtract 6561 from 6790 to get 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Going ahead to step 10:
When dividing 2290 by 729, we get 3 with a remainder of 103.
Put 3 as the next digit of the answer. 
Result so far: 118678.93
Subtract 2187 from 2290 to get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Advancing to step 11:
If we divide 1030 by 729, we get 1 and a remainder of 301.
The number 1 becomes the next digit in our result. 
Result so far: 118678.931
Subtracting 729 from 1030 leaves us with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Advancing to step 12:
729 can be fit into 3010 4 times, resulting in a remainder of 94.
Use 4 as the next digit of our solution. 
Result so far: 118678.9314
The remainder is 94 after subtracting 2916 from 3010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 13:
729 can be fit into 940 1 times, resulting in a remainder of 211.
Put 1 as the next digit of the answer. 
Result so far: 118678.93141
Deduct 729 from 940 and we're left with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Advancing to step 14:
If we divide 2110 by 729, we get 2 and a remainder of 652.
The number 2 becomes the next digit in our result. 
Result so far: 118678.931412
Subtracting 1458 from 2110 leaves us with 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Going ahead to step 15:
The number 729 fits into 6520 8 times, leaving a remainder of 688.
Record the quotient 8 as the next digit in the result. 
Result so far: 118678.9314128
Deduct 5832 from 6520 and we're left with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Let's proceed to step 16:
When dividing 6880 by 729, we get 9 with a remainder of 319.
Put 9 as the next digit of the answer. 
Result so far: 118678.93141289
If we subtract 6561 from 6880, we get 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

In conclusion, the division gives 118678.93141289 with a balance of 3.19e-07.
