We're dividing 90324 by 43 
The aim is to understand the frequency of 43 in 90324.

Step 1:
43 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 43

Moving on to step 2:
If we divide 90 by 43, we get 2 and a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 86 from 90 to get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 43

Let's proceed to step 3:
43 divided by 43 is 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 21.0
The remainder is 0 after subtracting 43 from 43.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 43

Let's proceed to step 4:
43 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 210.0
Subtract 0 from 2 to get 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 43

On to step 5:
24 divided by 43 is 0 with a remainder of 24.
The next digit of our result is 0. 
Result so far: 2100.0
Subtracting 0 from 24 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 6:
When dividing 240 by 43, we get 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 2100.5
If we subtract 215 from 240, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 7:
250 divided by 43 is 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 2100.55
Subtract 215 from 250 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 2100.55, with a leftover of 0.035.
