We're dividing 36323 by 90 
The aim is to understand the frequency of 90 in 36323.

On to step 1:
3 divided by 90 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 90

Advancing to step 2:
90 can be fit into 36 0 times, resulting in a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 36, we get 36.
Fetch the next digit (3) from the dividend, attach it to 36 and continue: 363 / 90

On to step 3:
90 goes into 363 4 times with a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 360 from 363 leaves us with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 90

Advancing to step 4:
90 goes into 32 0 times with a remainder of 32.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
Subtracting 0 from 32 leaves us with 32.
Append the next digit (3) from the dividend to 32 and continue with: 323 / 90

On to step 5:
When dividing 323 by 90, we get 3 with a remainder of 53.
The number 3 becomes the next digit in our result. 
Result so far: 403.0
Subtract 270 from 323 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 6:
90 can be fit into 530 5 times, resulting in a remainder of 80.
Write down 5 as next digit of the result. 
Result so far: 403.5
If we take 450 away from 530, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 7:
The number 90 fits into 800 8 times, leaving a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 403.58
Subtracting 720 from 800 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 8:
If we divide 800 by 90, we get 8 and a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 403.588
If we take 720 away from 800, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final result is 403.588 with a remainder of 0.008.
