We look at the division of 55991 by 79 
We want to divide 55991 by 79.

On to step 1:
5 divided by 79 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 79

Advancing to step 2:
The number 79 fits into 55 0 times, leaving a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Grab the next digit (9) from the dividend, add it to 55, then carry on: 559 / 79

Let's proceed to step 3:
559 divided by 79 is 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 6 after subtracting 553 from 559.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 79

On to step 4:
79 can be fit into 69 0 times, resulting in a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
Subtract 0 from 69 to get 69.
Append the next digit (1) from the dividend to 69 and continue with: 691 / 79

Step 5:
691 divided by 79 is 8 with a remainder of 59.
Write down 8 as next digit of the result. 
Result so far: 708.0
If we subtract 632 from 691, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 6:
When dividing 590 by 79, we get 7 with a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 708.7
If we subtract 553 from 590, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 7:
When dividing 370 by 79, we get 4 with a remainder of 54.
Put 4 as the next digit of the answer. 
Result so far: 708.74
The remainder is 54 after subtracting 316 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 8:
The number 79 fits into 540 6 times, leaving a remainder of 66.
The next digit of our result is 6. 
Result so far: 708.746
Subtracting 474 from 540 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 9:
79 goes into 660 8 times with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 708.7468
Subtracting 632 from 660 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
When dividing 280 by 79, we get 3 with a remainder of 43.
The next digit of our result is 3. 
Result so far: 708.74683
If we take 237 away from 280, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 11:
When dividing 430 by 79, we get 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 708.746835
Subtracting 395 from 430 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 12:
When dividing 350 by 79, we get 4 with a remainder of 34.
The next digit of our result is 4. 
Result so far: 708.7468354
Deduct 316 from 350 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 13:
If we divide 340 by 79, we get 4 and a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 708.74683544
If we take 316 away from 340, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 708.74683544 with a remaining 2.4e-08.
