688939 divided by 9 
We're looking to find how many times 9 goes into 688939.

Advancing to step 1:
9 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 9

Moving on to step 2:
The number 9 fits into 68 7 times, leaving a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 63 from 68 to get 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 9

Step 3:
If we divide 58 by 9, we get 6 and a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
If we subtract 54 from 58, we get 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 9

Going ahead to step 4:
49 divided by 9 is 5 with a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 765.0
If we take 45 away from 49, we end up with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 9

Moving on to step 5:
If we divide 43 by 9, we get 4 and a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 7654.0
The remainder is 7 after subtracting 36 from 43.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 9

Step 6:
79 divided by 9 is 8 with a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 76548.0
Subtracting 72 from 79 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
9 can be fit into 70 7 times, resulting in a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 76548.7
Subtracting 63 from 70 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
9 can be fit into 70 7 times, resulting in a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 76548.77
Subtract 63 from 70 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

After the division, we end up with 76548.77 and a remainder of 0.007.
