687588 ÷ 9 
We want to figure out the number of times 687588 can be divided by 9.

Advancing to step 1:
When dividing 6 by 9, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 9

On to step 2:
The number 9 fits into 68 7 times, leaving a remainder of 5.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 5 after subtracting 63 from 68.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 9

On to step 3:
The number 9 fits into 57 6 times, leaving a remainder of 3.
The next digit of our result is 6. 
Result so far: 76.0
Subtract 54 from 57 to get 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 9

Moving on to step 4:
9 can be fit into 35 3 times, resulting in a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 763.0
If we take 27 away from 35, we end up with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 9

Moving on to step 5:
9 can be fit into 88 9 times, resulting in a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 7639.0
The remainder is 7 after subtracting 81 from 88.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 9

Going ahead to step 6:
9 goes into 78 8 times with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 76398.0
Subtract 72 from 78 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
60 divided by 9 is 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 76398.6
The remainder is 6 after subtracting 54 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
60 divided by 9 is 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 76398.66
If we subtract 54 from 60, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 76398.66 and a remainder of 0.006.
