680397 divided by 9 
Let's see how many times 9 fits into 680397.

Step 1:
6 divided by 9 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 9

Moving on to step 2:
9 goes into 68 7 times with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 63 away from 68, we end up with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 9

Advancing to step 3:
50 divided by 9 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 75.0
If we subtract 45 from 50, we get 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 9

Going ahead to step 4:
53 divided by 9 is 5 with a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 755.0
If we take 45 away from 53, we end up with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 9

Going ahead to step 5:
9 goes into 89 9 times with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 7559.0
If we take 81 away from 89, we end up with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 9

Step 6:
The number 9 fits into 87 9 times, leaving a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 75599.0
Subtract 81 from 87 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:
If we divide 60 by 9, we get 6 and a remainder of 6.
The next digit of our result is 6. 
Result so far: 75599.6
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.

Step 8:
If we divide 60 by 9, we get 6 and a remainder of 6.
The next digit of our result is 6. 
Result so far: 75599.66
Deduct 54 from 60 and we're left with 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 75599.66 and a remainder of 0.006.
