We look at the division of 12792401 by 996 
Let's see how many times 996 fits into 12792401.

Step 1:
The number 996 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 996

Going ahead to step 2:
If we divide 12 by 996, we get 0 and a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Append the next digit (7) from the dividend to 12 and continue with: 127 / 996

Moving on to step 3:
The number 996 fits into 127 0 times, leaving a remainder of 127.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 127, we get 127.
Include the next digit (9) from the dividend after 127, then repeat: 1279 / 996

Going ahead to step 4:
The number 996 fits into 1279 1 times, leaving a remainder of 283.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 996 from 1279 and we're left with 283.
Bring next digit (2) of the dividend behind the 283 and repeat the process: 2832 / 996

Going ahead to step 5:
2832 divided by 996 is 2 with a remainder of 840.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 1992 from 2832 leaves us with 840.
Take the next digit (4) from the dividend and append it to 840, then repeat: 8404 / 996

Advancing to step 6:
8404 divided by 996 is 8 with a remainder of 436.
Put 8 as the next digit of the answer. 
Result so far: 128.0
Subtract 7968 from 8404 to get 436.
Grab the next digit (0) from the dividend, add it to 436, then carry on: 4360 / 996

Advancing to step 7:
If we divide 4360 by 996, we get 4 and a remainder of 376.
Write down 4 as next digit of the result. 
Result so far: 1284.0
Deduct 3984 from 4360 and we're left with 376.
Grab the next digit (1) from the dividend, add it to 376, then carry on: 3761 / 996

Let's proceed to step 8:
The number 996 fits into 3761 3 times, leaving a remainder of 773.
Put 3 as the next digit of the answer. 
Result so far: 12843.0
The remainder is 773 after subtracting 2988 from 3761.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7730, and continue the process.

Moving on to step 9:
7730 divided by 996 is 7 with a remainder of 758.
The number 7 becomes the next digit in our result. 
Result so far: 12843.7
Subtract 6972 from 7730 to get 758.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7580, and continue the process.

On to step 10:
996 goes into 7580 7 times with a remainder of 608.
The number 7 becomes the next digit in our result. 
Result so far: 12843.77
Subtract 6972 from 7580 to get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

The final result is 12843.77 with a remainder of 0.608.
