688148 ÷ 9 
We want to figure out the number of times 688148 can be divided by 9.

On to step 1:
When dividing 6 by 9, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 9

Let's proceed to step 2:
If we divide 68 by 9, we get 7 and a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 5 after subtracting 63 from 68.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 9

Advancing to step 3:
9 goes into 58 6 times with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 76.0
If we subtract 54 from 58, we get 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 9

On to step 4:
When dividing 41 by 9, we get 4 with a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 764.0
Deduct 36 from 41 and we're left with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 9

On to step 5:
54 divided by 9 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 7646.0
If we subtract 54 from 54, we get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 9

On to step 6:
If we divide 8 by 9, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 76460.0
The remainder is 8 after subtracting 0 from 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
80 divided by 9 is 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 76460.8
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
The number 9 fits into 80 8 times, leaving a remainder of 8.
The next digit of our result is 8. 
Result so far: 76460.88
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 76460.88 and a remainder of 0.008.
