We look at the division of 86797708 by 638 
Our goal is to divide 86797708 by 638.

Going ahead to step 1:
8 divided by 638 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 638

Advancing to step 2:
638 goes into 86 0 times with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Take the next digit (7) from the dividend and append it to 86, then repeat: 867 / 638

On to step 3:
638 can be fit into 867 1 times, resulting in a remainder of 229.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 638 from 867 leaves us with 229.
Grab the next digit (9) from the dividend, add it to 229, then carry on: 2299 / 638

Let's proceed to step 4:
When dividing 2299 by 638, we get 3 with a remainder of 385.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 1914 from 2299 leaves us with 385.
Grab the next digit (7) from the dividend, add it to 385, then carry on: 3857 / 638

Going ahead to step 5:
638 can be fit into 3857 6 times, resulting in a remainder of 29.
Record the quotient 6 as the next digit in the result. 
Result so far: 136.0
Subtract 3828 from 3857 to get 29.
Include the next digit (7) from the dividend after 29, then repeat: 297 / 638

On to step 6:
When dividing 297 by 638, we get 0 with a remainder of 297.
The next digit of our result is 0. 
Result so far: 1360.0
If we take 0 away from 297, we end up with 297.
Include the next digit (0) from the dividend after 297, then repeat: 2970 / 638

On to step 7:
If we divide 2970 by 638, we get 4 and a remainder of 418.
Record the quotient 4 as the next digit in the result. 
Result so far: 13604.0
If we take 2552 away from 2970, we end up with 418.
Fetch the next digit (8) from the dividend, attach it to 418 and continue: 4188 / 638

Going ahead to step 8:
The number 638 fits into 4188 6 times, leaving a remainder of 360.
Put 6 as the next digit of the answer. 
Result so far: 136046.0
If we subtract 3828 from 4188, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 9:
638 goes into 3600 5 times with a remainder of 410.
Record the quotient 5 as the next digit in the result. 
Result so far: 136046.5
If we take 3190 away from 3600, we end up with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Let's proceed to step 10:
638 goes into 4100 6 times with a remainder of 272.
The number 6 becomes the next digit in our result. 
Result so far: 136046.56
If we subtract 3828 from 4100, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Step 11:
638 can be fit into 2720 4 times, resulting in a remainder of 168.
Put 4 as the next digit of the answer. 
Result so far: 136046.564
The remainder is 168 after subtracting 2552 from 2720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Step 12:
The number 638 fits into 1680 2 times, leaving a remainder of 404.
Use 2 as the next digit of our solution. 
Result so far: 136046.5642
If we take 1276 away from 1680, we end up with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Step 13:
638 can be fit into 4040 6 times, resulting in a remainder of 212.
Use 6 as the next digit of our solution. 
Result so far: 136046.56426
If we subtract 3828 from 4040, we get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Moving on to step 14:
When dividing 2120 by 638, we get 3 with a remainder of 206.
The number 3 becomes the next digit in our result. 
Result so far: 136046.564263
Subtracting 1914 from 2120 leaves us with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Let's proceed to step 15:
The number 638 fits into 2060 3 times, leaving a remainder of 146.
The next digit of our result is 3. 
Result so far: 136046.5642633
If we subtract 1914 from 2060, we get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Our division results in 136046.5642633 with a remaining 1.46e-06.
