684320 ÷ 9 
We want to figure out the number of times 684320 can be divided by 9.

Let's proceed to step 1:
9 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 9

Moving on to step 2:
9 goes into 68 7 times with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 63 from 68 leaves us with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 9

Moving on to step 3:
When dividing 54 by 9, we get 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 76.0
Deduct 54 from 54 and we're left with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 9

On to step 4:
9 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 760.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 9

Going ahead to step 5:
9 can be fit into 32 3 times, resulting in a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 7603.0
The remainder is 5 after subtracting 27 from 32.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 9

Advancing to step 6:
9 can be fit into 50 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 76035.0
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
50 divided by 9 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 76035.5
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
The number 9 fits into 50 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 76035.55
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

In conclusion, the division gives 76035.55 with a balance of 0.005.
