We divide 85612836 by 9
The aim is to understand the frequency of 9 in 85612836.

Step 1:
8 divided by 9 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 9

Moving on to step 2:
The number 9 fits into 85 9 times, leaving a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 81 from 85 leaves us with 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 9

Step 3:
The number 9 fits into 46 5 times, leaving a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 95.0
Subtract 45 from 46 to get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 9

Step 4:
When dividing 11 by 9, we get 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 951.0
If we subtract 9 from 11, we get 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 9

Step 5:
The number 9 fits into 22 2 times, leaving a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 9512.0
Deduct 18 from 22 and we're left with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 9

Advancing to step 6:
The number 9 fits into 48 5 times, leaving a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 95125.0
Deduct 45 from 48 and we're left with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 9

Let's proceed to step 7:
9 can be fit into 33 3 times, resulting in a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 951253.0
If we subtract 27 from 33, we get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 9

Going ahead to step 8:
9 goes into 66 7 times with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 9512537.0
Deduct 63 from 66 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 9:
9 goes into 30 3 times with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 9512537.3
The remainder is 3 after subtracting 27 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 10:
9 goes into 30 3 times with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 9512537.33
The remainder is 3 after subtracting 27 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final outcome is 9512537.33, with a leftover of 0.003.
