We divide 811031 by 9
The aim is to understand the frequency of 9 in 811031.

Moving on to step 1:
9 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 9

On to step 2:
When dividing 81 by 9, we get 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 81 away from 81, we end up with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 9

Going ahead to step 3:
If we divide 1 by 9, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 90.0
Subtract 0 from 1 to get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 9

Step 4:
The number 9 fits into 10 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 901.0
If we take 9 away from 10, we end up with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 9

Advancing to step 5:
9 goes into 13 1 times with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 9011.0
Subtract 9 from 13 to get 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 9

Moving on to step 6:
When dividing 41 by 9, we get 4 with a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 90114.0
Subtracting 36 from 41 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
When dividing 50 by 9, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 90114.5
Deduct 45 from 50 and we're left with 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:
9 can be fit into 50 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 90114.55
If we subtract 45 from 50, we 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.

The final result is 90114.55 with a remainder of 0.005.
