We divide 86620691 by 799
We're looking to find how many times 799 goes into 86620691.

Step 1:
The number 799 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 799

On to step 2:
When dividing 86 by 799, we get 0 with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Grab the next digit (6) from the dividend, add it to 86, then carry on: 866 / 799

Advancing to step 3:
799 can be fit into 866 1 times, resulting in a remainder of 67.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 67 after subtracting 799 from 866.
Include the next digit (2) from the dividend after 67, then repeat: 672 / 799

Step 4:
672 divided by 799 is 0 with a remainder of 672.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 672 after subtracting 0 from 672.
Grab the next digit (0) from the dividend, add it to 672, then carry on: 6720 / 799

Going ahead to step 5:
If we divide 6720 by 799, we get 8 and a remainder of 328.
Write down 8 as next digit of the result. 
Result so far: 108.0
Subtracting 6392 from 6720 leaves us with 328.
Fetch the next digit (6) from the dividend, attach it to 328 and continue: 3286 / 799

On to step 6:
3286 divided by 799 is 4 with a remainder of 90.
Write down 4 as next digit of the result. 
Result so far: 1084.0
The remainder is 90 after subtracting 3196 from 3286.
Bring next digit (9) of the dividend behind the 90 and repeat the process: 909 / 799

On to step 7:
The number 799 fits into 909 1 times, leaving a remainder of 110.
Put 1 as the next digit of the answer. 
Result so far: 10841.0
If we take 799 away from 909, we end up with 110.
Take the next digit (1) from the dividend and append it to 110, then repeat: 1101 / 799

On to step 8:
799 goes into 1101 1 times with a remainder of 302.
The next digit of our result is 1. 
Result so far: 108411.0
Subtract 799 from 1101 to get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Let's proceed to step 9:
The number 799 fits into 3020 3 times, leaving a remainder of 623.
Use 3 as the next digit of our solution. 
Result so far: 108411.3
Subtracting 2397 from 3020 leaves us with 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Let's proceed to step 10:
6230 divided by 799 is 7 with a remainder of 637.
Put 7 as the next digit of the answer. 
Result so far: 108411.37
If we subtract 5593 from 6230, we get 637.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6370, and continue the process.

Let's proceed to step 11:
The number 799 fits into 6370 7 times, leaving a remainder of 777.
The number 7 becomes the next digit in our result. 
Result so far: 108411.377
Subtracting 5593 from 6370 leaves us with 777.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7770, and continue the process.

The final result is 108411.377 with a remainder of 0.0777.
