We look at the division of 688668 by 79 
Our goal is to divide 688668 by 79.

Step 1:
79 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 79

Step 2:
79 can be fit into 68 0 times, resulting in a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Fetch the next digit (8) from the dividend, attach it to 68 and continue: 688 / 79

Let's proceed to step 3:
79 goes into 688 8 times with a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 632 from 688, we get 56.
Include the next digit (6) from the dividend after 56, then repeat: 566 / 79

Going ahead to step 4:
The number 79 fits into 566 7 times, leaving a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 87.0
If we subtract 553 from 566, we get 13.
Append the next digit (6) from the dividend to 13 and continue with: 136 / 79

Advancing to step 5:
When dividing 136 by 79, we get 1 with a remainder of 57.
The next digit of our result is 1. 
Result so far: 871.0
If we subtract 79 from 136, we get 57.
Include the next digit (8) from the dividend after 57, then repeat: 578 / 79

Going ahead to step 6:
578 divided by 79 is 7 with a remainder of 25.
Write down 7 as next digit of the result. 
Result so far: 8717.0
Subtracting 553 from 578 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 7:
79 can be fit into 250 3 times, resulting in a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 8717.3
Deduct 237 from 250 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 8:
79 goes into 130 1 times with a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 8717.31
If we subtract 79 from 130, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 9:
When dividing 510 by 79, we get 6 with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 8717.316
If we take 474 away from 510, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 10:
If we divide 360 by 79, we get 4 and a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 8717.3164
If we take 316 away from 360, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 11:
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: 8717.31645
If we take 395 away from 440, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 12:
If we divide 450 by 79, we get 5 and a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 8717.316455
Deduct 395 from 450 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

After the division, we end up with 8717.316455 and a remainder of 5.5e-06.
