We're dividing 810936 by 9 
The aim is to understand the frequency of 9 in 810936.

Moving on to step 1:
The number 9 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 9

Let's proceed to step 2:
9 can be fit into 81 9 times, resulting in a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 81 from 81 and we're left with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 9

Step 3:
0 divided by 9 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
If we take 0 away from 0, we end up with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 9

Step 4:
9 can be fit into 9 1 times, resulting in a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 901.0
Subtracting 9 from 9 leaves us with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 9

Step 5:
When dividing 3 by 9, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 9010.0
Subtract 0 from 3 to get 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 9

On to step 6:
If we divide 36 by 9, we get 4 and a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 90104.0
If we take 36 away from 36, we end up 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 7:
If we divide 0 by 9, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 90104.0
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.

Advancing to step 8:
The number 9 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 90104.0
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.

After the division, we end up with 90104.0 and a remainder of 0.0.
