We're dividing 687688 by 80 
Let's see how many times 80 fits into 687688.

Step 1:
6 divided by 80 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 80

Step 2:
If we divide 68 by 80, we get 0 and a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Take the next digit (7) from the dividend and append it to 68, then repeat: 687 / 80

Let's proceed to step 3:
If we divide 687 by 80, we get 8 and a remainder of 47.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 640 from 687 to get 47.
Grab the next digit (6) from the dividend, add it to 47, then carry on: 476 / 80

Let's proceed to step 4:
476 divided by 80 is 5 with a remainder of 76.
Record the quotient 5 as the next digit in the result. 
Result so far: 85.0
The remainder is 76 after subtracting 400 from 476.
Fetch the next digit (8) from the dividend, attach it to 76 and continue: 768 / 80

Moving on to step 5:
If we divide 768 by 80, we get 9 and a remainder of 48.
Use 9 as the next digit of our solution. 
Result so far: 859.0
Subtracting 720 from 768 leaves us with 48.
Append the next digit (8) from the dividend to 48 and continue with: 488 / 80

Let's proceed to step 6:
80 can be fit into 488 6 times, resulting in a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 8596.0
The remainder is 8 after subtracting 480 from 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
80 can be fit into 80 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 8596.1
If we subtract 80 from 80, 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.

Advancing to step 8:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 8596.1
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 9:
80 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8596.1
If we subtract 0 from 0, 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.

The final result is 8596.1 with a remainder of 0.0.
