We divide 811320 by 9
We're looking to find how many times 9 goes into 811320.

Going ahead to step 1:
When dividing 8 by 9, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 9

Step 2:
9 can be fit into 81 9 times, resulting in a remainder of 0.
The next digit of our result is 9. 
Result so far: 9.0
If we take 81 away from 81, we end up with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 9

Advancing to step 3:
9 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 90.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 9

Step 4:
The number 9 fits into 13 1 times, leaving a remainder of 4.
The next digit of our result is 1. 
Result so far: 901.0
The remainder is 4 after subtracting 9 from 13.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 9

Advancing to step 5:
9 can be fit into 42 4 times, resulting in a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 9014.0
Subtract 36 from 42 to get 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 9

Step 6:
9 can be fit into 60 6 times, resulting in a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 90146.0
If we take 54 away from 60, we end up 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.

Going ahead to step 7:
9 goes into 60 6 times with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 90146.6
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.

Let's proceed to step 8:
9 goes into 60 6 times with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 90146.66
Subtract 54 from 60 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.

The final result is 90146.66 with a remainder of 0.006.
