Let's divide 74857728 by 81
We want to figure out the number of times 74857728 can be divided by 81.

Moving on to step 1:
When dividing 7 by 81, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 81

Advancing to step 2:
The number 81 fits into 74 0 times, leaving a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Append the next digit (8) from the dividend to 74 and continue with: 748 / 81

Let's proceed to step 3:
The number 81 fits into 748 9 times, leaving a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 729 from 748 leaves us with 19.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 81

Advancing to step 4:
If we divide 195 by 81, we get 2 and a remainder of 33.
The next digit of our result is 2. 
Result so far: 92.0
If we subtract 162 from 195, we get 33.
Include the next digit (7) from the dividend after 33, then repeat: 337 / 81

Going ahead to step 5:
If we divide 337 by 81, we get 4 and a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 924.0
The remainder is 13 after subtracting 324 from 337.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 81

Let's proceed to step 6:
137 divided by 81 is 1 with a remainder of 56.
The next digit of our result is 1. 
Result so far: 9241.0
Subtract 81 from 137 to get 56.
Append the next digit (2) from the dividend to 56 and continue with: 562 / 81

Advancing to step 7:
If we divide 562 by 81, we get 6 and a remainder of 76.
Put 6 as the next digit of the answer. 
Result so far: 92416.0
If we take 486 away from 562, we end up with 76.
Append the next digit (8) from the dividend to 76 and continue with: 768 / 81

Step 8:
When dividing 768 by 81, we get 9 with a remainder of 39.
The next digit of our result is 9. 
Result so far: 924169.0
The remainder is 39 after subtracting 729 from 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 9:
81 goes into 390 4 times with a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 924169.4
Subtract 324 from 390 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 10:
If we divide 660 by 81, we get 8 and a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 924169.48
Subtracting 648 from 660 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
If we divide 120 by 81, we get 1 and a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 924169.481
Subtracting 81 from 120 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 12:
81 can be fit into 390 4 times, resulting in a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 924169.4814
Subtracting 324 from 390 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 13:
The number 81 fits into 660 8 times, leaving a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 924169.48148
If we take 648 away from 660, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 14:
When dividing 120 by 81, we get 1 with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 924169.481481
Subtract 81 from 120 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 15:
81 goes into 390 4 times with a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 924169.4814814
If we subtract 324 from 390, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 16:
If we divide 660 by 81, we get 8 and a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 924169.48148148
If we take 648 away from 660, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 924169.48148148, with a leftover of 1.2e-08.
