Let's divide 90516 by 9
The aim is to understand the frequency of 9 in 90516.

Moving on to step 1:
9 can be fit into 9 1 times, resulting in a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
If we take 9 away from 9, we end up with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 9

Step 2:
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: 10.0
The remainder is 0 after subtracting 0 from 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 9

Let's proceed to step 3:
When dividing 5 by 9, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
Subtract 0 from 5 to get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 9

On to step 4:
The number 9 fits into 51 5 times, leaving a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 1005.0
Deduct 45 from 51 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 9

Going ahead to step 5:
9 goes into 66 7 times with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 10057.0
If we subtract 63 from 66, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 6:
The number 9 fits into 30 3 times, leaving a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 10057.3
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.

Going ahead to step 7:
9 can be fit into 30 3 times, resulting in a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 10057.33
If we take 27 away from 30, we end up 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.

The final result is 10057.33 with a remainder of 0.003.
