Let's divide 86766082 by 638
We're looking to find how many times 638 goes into 86766082.

Moving on to step 1:
If we divide 8 by 638, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 638

On to step 2:
When dividing 86 by 638, we get 0 with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Grab the next digit (7) from the dividend, add it to 86, then carry on: 867 / 638

Moving on to step 3:
If we divide 867 by 638, we get 1 and a remainder of 229.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 638 from 867 to get 229.
Bring next digit (6) of the dividend behind the 229 and repeat the process: 2296 / 638

Step 4:
The number 638 fits into 2296 3 times, leaving a remainder of 382.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 1914 away from 2296, we end up with 382.
Grab the next digit (6) from the dividend, add it to 382, then carry on: 3826 / 638

Moving on to step 5:
3826 divided by 638 is 5 with a remainder of 636.
Use 5 as the next digit of our solution. 
Result so far: 135.0
The remainder is 636 after subtracting 3190 from 3826.
Take the next digit (0) from the dividend and append it to 636, then repeat: 6360 / 638

Advancing to step 6:
If we divide 6360 by 638, we get 9 and a remainder of 618.
Write down 9 as next digit of the result. 
Result so far: 1359.0
Subtract 5742 from 6360 to get 618.
Bring next digit (8) of the dividend behind the 618 and repeat the process: 6188 / 638

Let's proceed to step 7:
If we divide 6188 by 638, we get 9 and a remainder of 446.
Write down 9 as next digit of the result. 
Result so far: 13599.0
If we take 5742 away from 6188, we end up with 446.
Fetch the next digit (2) from the dividend, attach it to 446 and continue: 4462 / 638

Step 8:
If we divide 4462 by 638, we get 6 and a remainder of 634.
The number 6 becomes the next digit in our result. 
Result so far: 135996.0
Subtract 3828 from 4462 to get 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

Moving on to step 9:
638 goes into 6340 9 times with a remainder of 598.
Write down 9 as next digit of the result. 
Result so far: 135996.9
Subtracting 5742 from 6340 leaves us with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Going ahead to step 10:
5980 divided by 638 is 9 with a remainder of 238.
Use 9 as the next digit of our solution. 
Result so far: 135996.99
If we subtract 5742 from 5980, we get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

The quotient of the division is 135996.99, and the remainder is 0.238.
