11324 divided by 90 
The aim is to understand the frequency of 90 in 11324.

Step 1:
If we divide 1 by 90, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 90

Moving on to step 2:
If we divide 11 by 90, we get 0 and a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 11 and we're left with 11.
Bring next digit (3) of the dividend behind the 11 and repeat the process: 113 / 90

Let's proceed to step 3:
When dividing 113 by 90, we get 1 with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 90 from 113 and we're left with 23.
Append the next digit (2) from the dividend to 23 and continue with: 232 / 90

On to step 4:
232 divided by 90 is 2 with a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 180 away from 232, we end up with 52.
Append the next digit (4) from the dividend to 52 and continue with: 524 / 90

Advancing to step 5:
The number 90 fits into 524 5 times, leaving a remainder of 74.
The next digit of our result is 5. 
Result so far: 125.0
If we subtract 450 from 524, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 6:
90 goes into 740 8 times with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 125.8
Deduct 720 from 740 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 7:
90 goes into 200 2 times with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 125.82
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
90 can be fit into 200 2 times, resulting in a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 125.822
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 125.822, and the remainder is 0.002.
