We look at the division of 242331 by 54 
The aim is to understand the frequency of 54 in 242331.

Step 1:
If we divide 2 by 54, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 54

Step 2:
54 can be fit into 24 0 times, resulting in a remainder of 24.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 24 after subtracting 0 from 24.
Take the next digit (2) from the dividend and append it to 24, then repeat: 242 / 54

Let's proceed to step 3:
242 divided by 54 is 4 with a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 26 after subtracting 216 from 242.
Grab the next digit (3) from the dividend, add it to 26, then carry on: 263 / 54

On to step 4:
263 divided by 54 is 4 with a remainder of 47.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
Deduct 216 from 263 and we're left with 47.
Include the next digit (3) from the dividend after 47, then repeat: 473 / 54

Let's proceed to step 5:
54 can be fit into 473 8 times, resulting in a remainder of 41.
The next digit of our result is 8. 
Result so far: 448.0
Subtracting 432 from 473 leaves us with 41.
Fetch the next digit (1) from the dividend, attach it to 41 and continue: 411 / 54

Let's proceed to step 6:
411 divided by 54 is 7 with a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 4487.0
Subtract 378 from 411 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 7:
54 can be fit into 330 6 times, resulting in a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 4487.6
The remainder is 6 after subtracting 324 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
When dividing 60 by 54, we get 1 with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 4487.61
Subtract 54 from 60 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
54 can be fit into 60 1 times, resulting in a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 4487.611
If we subtract 54 from 60, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 4487.611 with a remainder of 0.0006.
