We're dividing 687591 by 79 
Let's see how many times 79 fits into 687591.

On to step 1:
When dividing 6 by 79, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 79

On to step 2:
79 can be fit into 68 0 times, resulting in a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Append the next digit (7) from the dividend to 68 and continue with: 687 / 79

Let's proceed to step 3:
79 goes into 687 8 times with a remainder of 55.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 632 from 687, we get 55.
Grab the next digit (5) from the dividend, add it to 55, then carry on: 555 / 79

On to step 4:
When dividing 555 by 79, we get 7 with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 87.0
If we subtract 553 from 555, we get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 79

On to step 5:
The number 79 fits into 29 0 times, leaving a remainder of 29.
The next digit of our result is 0. 
Result so far: 870.0
Subtract 0 from 29 to get 29.
Append the next digit (1) from the dividend to 29 and continue with: 291 / 79

Step 6:
If we divide 291 by 79, we get 3 and a remainder of 54.
Record the quotient 3 as the next digit in the result. 
Result so far: 8703.0
Subtracting 237 from 291 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 7:
79 can be fit into 540 6 times, resulting in a remainder of 66.
The number 6 becomes the next digit in our result. 
Result so far: 8703.6
Deduct 474 from 540 and we're left 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.

On to step 8:
The number 79 fits into 660 8 times, leaving a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 8703.68
Subtract 632 from 660 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
The number 79 fits into 280 3 times, leaving a remainder of 43.
The number 3 becomes the next digit in our result. 
Result so far: 8703.683
Deduct 237 from 280 and we're left 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.

Let's proceed to step 10:
When dividing 430 by 79, we get 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 8703.6835
Deduct 395 from 430 and we're left 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.

Moving on to step 11:
If we divide 350 by 79, we get 4 and a remainder of 34.
The next digit of our result is 4. 
Result so far: 8703.68354
Subtracting 316 from 350 leaves us 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.

On to step 12:
When dividing 340 by 79, we get 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 8703.683544
Subtract 316 from 340 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 8703.683544, with a leftover of 2.4e-06.
