86681354 divided by 493 
We want to figure out the number of times 86681354 can be divided by 493.

On to step 1:
The number 493 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 493

Step 2:
The number 493 fits into 86 0 times, leaving a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Take the next digit (6) from the dividend and append it to 86, then repeat: 866 / 493

Moving on to step 3:
866 divided by 493 is 1 with a remainder of 373.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 373 after subtracting 493 from 866.
Append the next digit (8) from the dividend to 373 and continue with: 3738 / 493

Step 4:
493 goes into 3738 7 times with a remainder of 287.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we take 3451 away from 3738, we end up with 287.
Fetch the next digit (1) from the dividend, attach it to 287 and continue: 2871 / 493

Step 5:
If we divide 2871 by 493, we get 5 and a remainder of 406.
Put 5 as the next digit of the answer. 
Result so far: 175.0
If we subtract 2465 from 2871, we get 406.
Fetch the next digit (3) from the dividend, attach it to 406 and continue: 4063 / 493

On to step 6:
493 can be fit into 4063 8 times, resulting in a remainder of 119.
The number 8 becomes the next digit in our result. 
Result so far: 1758.0
Subtract 3944 from 4063 to get 119.
Grab the next digit (5) from the dividend, add it to 119, then carry on: 1195 / 493

Going ahead to step 7:
1195 divided by 493 is 2 with a remainder of 209.
The number 2 becomes the next digit in our result. 
Result so far: 17582.0
The remainder is 209 after subtracting 986 from 1195.
Grab the next digit (4) from the dividend, add it to 209, then carry on: 2094 / 493

Going ahead to step 8:
When dividing 2094 by 493, we get 4 with a remainder of 122.
Write down 4 as next digit of the result. 
Result so far: 175824.0
Deduct 1972 from 2094 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Going ahead to step 9:
When dividing 1220 by 493, we get 2 with a remainder of 234.
Write down 2 as next digit of the result. 
Result so far: 175824.2
The remainder is 234 after subtracting 986 from 1220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

On to step 10:
493 goes into 2340 4 times with a remainder of 368.
Put 4 as the next digit of the answer. 
Result so far: 175824.24
Subtract 1972 from 2340 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Step 11:
If we divide 3680 by 493, we get 7 and a remainder of 229.
The number 7 becomes the next digit in our result. 
Result so far: 175824.247
Subtracting 3451 from 3680 leaves us with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Step 12:
When dividing 2290 by 493, we get 4 with a remainder of 318.
The next digit of our result is 4. 
Result so far: 175824.2474
If we subtract 1972 from 2290, we get 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Moving on to step 13:
3180 divided by 493 is 6 with a remainder of 222.
The number 6 becomes the next digit in our result. 
Result so far: 175824.24746
Deduct 2958 from 3180 and we're left with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

On to step 14:
493 goes into 2220 4 times with a remainder of 248.
The next digit of our result is 4. 
Result so far: 175824.247464
If we take 1972 away from 2220, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Going ahead to step 15:
493 can be fit into 2480 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 175824.2474645
Subtracting 2465 from 2480 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 16:
493 can be fit into 150 0 times, resulting in a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 175824.2474645
If we take 0 away from 150, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

After the division, we end up with 175824.2474645 and a remainder of 1.5e-07.
