We're dividing 13288996 by 879 
We want to divide 13288996 by 879.

Advancing to step 1:
879 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 879

Step 2:
If we divide 13 by 879, we get 0 and a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 879

Advancing to step 3:
When dividing 132 by 879, we get 0 with a remainder of 132.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 132 and we're left with 132.
Bring next digit (8) of the dividend behind the 132 and repeat the process: 1328 / 879

Let's proceed to step 4:
When dividing 1328 by 879, we get 1 with a remainder of 449.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 879 from 1328 leaves us with 449.
Take the next digit (8) from the dividend and append it to 449, then repeat: 4498 / 879

Moving on to step 5:
879 can be fit into 4498 5 times, resulting in a remainder of 103.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 4395 away from 4498, we end up with 103.
Grab the next digit (9) from the dividend, add it to 103, then carry on: 1039 / 879

Moving on to step 6:
When dividing 1039 by 879, we get 1 with a remainder of 160.
Write down 1 as next digit of the result. 
Result so far: 151.0
Deduct 879 from 1039 and we're left with 160.
Append the next digit (9) from the dividend to 160 and continue with: 1609 / 879

Moving on to step 7:
The number 879 fits into 1609 1 times, leaving a remainder of 730.
Record the quotient 1 as the next digit in the result. 
Result so far: 1511.0
Subtracting 879 from 1609 leaves us with 730.
Append the next digit (6) from the dividend to 730 and continue with: 7306 / 879

Moving on to step 8:
7306 divided by 879 is 8 with a remainder of 274.
The number 8 becomes the next digit in our result. 
Result so far: 15118.0
If we take 7032 away from 7306, we end up with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

On to step 9:
The number 879 fits into 2740 3 times, leaving a remainder of 103.
The number 3 becomes the next digit in our result. 
Result so far: 15118.3
Subtracting 2637 from 2740 leaves us with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Step 10:
879 can be fit into 1030 1 times, resulting in a remainder of 151.
Put 1 as the next digit of the answer. 
Result so far: 15118.31
Deduct 879 from 1030 and we're left with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Advancing to step 11:
The number 879 fits into 1510 1 times, leaving a remainder of 631.
The number 1 becomes the next digit in our result. 
Result so far: 15118.311
Deduct 879 from 1510 and we're left with 631.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6310, and continue the process.

The final outcome is 15118.311, with a leftover of 0.0631.
