We're dividing 870363 by 9 
Let's see how many times 9 fits into 870363.

Going ahead to step 1:
9 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 9

Moving on to step 2:
If we divide 87 by 9, we get 9 and a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 81 from 87 and we're left with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 9

Moving on to step 3:
When dividing 60 by 9, we get 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 96.0
If we take 54 away from 60, we end up with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 9

Step 4:
63 divided by 9 is 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 967.0
If we subtract 63 from 63, we get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 9

On to step 5:
6 divided by 9 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 9670.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 9

Moving on to step 6:
63 divided by 9 is 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 96707.0
If we subtract 63 from 63, we 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 7:
If we divide 0 by 9, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 96707.0
Subtracting 0 from 0 leaves us 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.

Let's proceed to step 8:
9 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 96707.0
If we subtract 0 from 0, we 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.

In conclusion, the division gives 96707.0 with a balance of 0.0.
