We look at the division of 248508 by 54 
The aim is to understand the frequency of 54 in 248508.

Step 1:
54 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 54

Moving on to step 2:
54 goes into 24 0 times with a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 24, we get 24.
Append the next digit (8) from the dividend to 24 and continue with: 248 / 54

Moving on to step 3:
248 divided by 54 is 4 with a remainder of 32.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 216 from 248, we get 32.
Grab the next digit (5) from the dividend, add it to 32, then carry on: 325 / 54

Going ahead to step 4:
When dividing 325 by 54, we get 6 with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 46.0
Deduct 324 from 325 and we're left with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 54

Advancing to step 5:
When dividing 10 by 54, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 460.0
Subtract 0 from 10 to get 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 54

Advancing to step 6:
54 goes into 108 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 4602.0
If we subtract 108 from 108, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
0 divided by 54 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4602.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
54 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 4602.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 4602.0, and the remainder is 0.0.
