We look at the division of 70830 by 9 
Let's see how many times 9 fits into 70830.

Moving on to step 1:
The number 9 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 9

On to step 2:
9 can be fit into 70 7 times, resulting in a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 63 from 70, we get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 9

On to step 3:
When dividing 78 by 9, we get 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 78.0
Subtracting 72 from 78 leaves us with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 9

Moving on to step 4:
The number 9 fits into 63 7 times, leaving a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 787.0
If we take 63 away from 63, we end up with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 9

On to step 5:
9 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7870.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 6:
When dividing 0 by 9, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7870.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
0 divided by 9 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7870.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 7870.0 with a balance of 0.0.
