Let's divide 991903 by 79
Our goal is to divide 991903 by 79.

Moving on to step 1:
9 divided by 79 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 79

Advancing to step 2:
If we divide 99 by 79, we get 1 and a remainder of 20.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 79 from 99 to get 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 79

On to step 3:
The number 79 fits into 201 2 times, leaving a remainder of 43.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 43 after subtracting 158 from 201.
Append the next digit (9) from the dividend to 43 and continue with: 439 / 79

Moving on to step 4:
439 divided by 79 is 5 with a remainder of 44.
Record the quotient 5 as the next digit in the result. 
Result so far: 125.0
Deduct 395 from 439 and we're left with 44.
Bring next digit (0) of the dividend behind the 44 and repeat the process: 440 / 79

On to step 5:
79 can be fit into 440 5 times, resulting in a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 1255.0
Subtracting 395 from 440 leaves us with 45.
Fetch the next digit (3) from the dividend, attach it to 45 and continue: 453 / 79

Moving on to step 6:
If we divide 453 by 79, we get 5 and a remainder of 58.
Write down 5 as next digit of the result. 
Result so far: 12555.0
Subtract 395 from 453 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 7:
The number 79 fits into 580 7 times, leaving a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 12555.7
Subtract 553 from 580 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 8:
270 divided by 79 is 3 with a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 12555.73
If we take 237 away from 270, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 9:
When dividing 330 by 79, we get 4 with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 12555.734
If we subtract 316 from 330, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
The number 79 fits into 140 1 times, leaving a remainder of 61.
Put 1 as the next digit of the answer. 
Result so far: 12555.7341
Subtracting 79 from 140 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 11:
79 goes into 610 7 times with a remainder of 57.
Write down 7 as next digit of the result. 
Result so far: 12555.73417
The remainder is 57 after subtracting 553 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 12:
If we divide 570 by 79, we get 7 and a remainder of 17.
The next digit of our result is 7. 
Result so far: 12555.734177
If we take 553 away from 570, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final result is 12555.734177 with a remainder of 1.7e-06.
