687717 divided by 80 
We want to divide 687717 by 80.

Let's proceed to step 1:
When dividing 6 by 80, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 80

Going ahead to step 2:
80 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.
Grab the next digit (7) from the dividend, add it to 68, then carry on: 687 / 80

Going ahead to step 3:
687 divided by 80 is 8 with a remainder of 47.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 640 away from 687, we end up with 47.
Grab the next digit (7) from the dividend, add it to 47, then carry on: 477 / 80

Step 4:
When dividing 477 by 80, we get 5 with a remainder of 77.
Record the quotient 5 as the next digit in the result. 
Result so far: 85.0
If we subtract 400 from 477, we get 77.
Append the next digit (1) from the dividend to 77 and continue with: 771 / 80

Moving on to step 5:
The number 80 fits into 771 9 times, leaving a remainder of 51.
The number 9 becomes the next digit in our result. 
Result so far: 859.0
If we subtract 720 from 771, we get 51.
Fetch the next digit (7) from the dividend, attach it to 51 and continue: 517 / 80

Advancing to step 6:
80 goes into 517 6 times with a remainder of 37.
The next digit of our result is 6. 
Result so far: 8596.0
The remainder is 37 after subtracting 480 from 517.
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:
The number 80 fits into 370 4 times, leaving a remainder of 50.
Use 4 as the next digit of our solution. 
Result so far: 8596.4
Deduct 320 from 370 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
If we divide 500 by 80, we get 6 and a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 8596.46
The remainder is 20 after subtracting 480 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
If we divide 200 by 80, we get 2 and a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 8596.462
Subtract 160 from 200 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
80 goes into 400 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 8596.4625
If we subtract 400 from 400, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
80 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8596.4625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8596.4625
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 8596.4625, and the remainder is 0.0.
