99300 ÷ 54 
The aim is to understand the frequency of 54 in 99300.

Going ahead to step 1:
54 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 54

Moving on to step 2:
If we divide 99 by 54, we get 1 and a remainder of 45.
The next digit of our result is 1. 
Result so far: 1.0
If we take 54 away from 99, we end up with 45.
Bring next digit (3) of the dividend behind the 45 and repeat the process: 453 / 54

Let's proceed to step 3:
54 can be fit into 453 8 times, resulting in a remainder of 21.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we subtract 432 from 453, we get 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 54

On to step 4:
When dividing 210 by 54, we get 3 with a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 183.0
Subtract 162 from 210 to get 48.
Include the next digit (0) from the dividend after 48, then repeat: 480 / 54

Let's proceed to step 5:
54 can be fit into 480 8 times, resulting in a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 1838.0
Subtracting 432 from 480 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 6:
54 can be fit into 480 8 times, resulting in a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 1838.8
Deduct 432 from 480 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 7:
If we divide 480 by 54, we get 8 and a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 1838.88
Subtract 432 from 480 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final result is 1838.88 with a remainder of 0.048.
