We look at the division of 680591 by 79 
We want to figure out the number of times 680591 can be divided by 79.

Going ahead to step 1:
When dividing 6 by 79, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 79

Advancing to step 2:
When dividing 68 by 79, we get 0 with a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Include the next digit (0) from the dividend after 68, then repeat: 680 / 79

Going ahead to step 3:
The number 79 fits into 680 8 times, leaving a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 632 from 680 to get 48.
Fetch the next digit (5) from the dividend, attach it to 48 and continue: 485 / 79

Going ahead to step 4:
79 goes into 485 6 times with a remainder of 11.
The next digit of our result is 6. 
Result so far: 86.0
The remainder is 11 after subtracting 474 from 485.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 79

Step 5:
79 can be fit into 119 1 times, resulting in a remainder of 40.
The next digit of our result is 1. 
Result so far: 861.0
If we subtract 79 from 119, we get 40.
Fetch the next digit (1) from the dividend, attach it to 40 and continue: 401 / 79

Let's proceed to step 6:
79 goes into 401 5 times with a remainder of 6.
The next digit of our result is 5. 
Result so far: 8615.0
Subtracting 395 from 401 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
79 goes into 60 0 times with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 8615.0
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
79 goes into 600 7 times with a remainder of 47.
Record the quotient 7 as the next digit in the result. 
Result so far: 8615.07
The remainder is 47 after subtracting 553 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 9:
If we divide 470 by 79, we get 5 and a remainder of 75.
The next digit of our result is 5. 
Result so far: 8615.075
Subtracting 395 from 470 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 10:
The number 79 fits into 750 9 times, leaving a remainder of 39.
The next digit of our result is 9. 
Result so far: 8615.0759
If we subtract 711 from 750, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 11:
79 goes into 390 4 times with a remainder of 74.
The number 4 becomes the next digit in our result. 
Result so far: 8615.07594
If we take 316 away from 390, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 12:
The number 79 fits into 740 9 times, leaving a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 8615.075949
Subtract 711 from 740 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 13:
290 divided by 79 is 3 with a remainder of 53.
Use 3 as the next digit of our solution. 
Result so far: 8615.0759493
Deduct 237 from 290 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 14:
The number 79 fits into 530 6 times, leaving a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 8615.07594936
If we take 474 away from 530, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The quotient of the division is 8615.07594936, and the remainder is 5.6e-08.
