We look at the division of 249529 by 54 
The aim is to understand the frequency of 54 in 249529.

On to 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
If we subtract 0 from 2, we get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 54

On to step 2:
When dividing 24 by 54, we get 0 with a remainder of 24.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 24 and we're left with 24.
Include the next digit (9) from the dividend after 24, then repeat: 249 / 54

Going ahead to step 3:
54 can be fit into 249 4 times, resulting in a remainder of 33.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 216 away from 249, we end up with 33.
Append the next digit (5) from the dividend to 33 and continue with: 335 / 54

Moving on to step 4:
The number 54 fits into 335 6 times, leaving a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
Deduct 324 from 335 and we're left with 11.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 54

Going ahead to step 5:
The number 54 fits into 112 2 times, leaving a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 462.0
Subtracting 108 from 112 leaves us with 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 54

Let's proceed to step 6:
54 can be fit into 49 0 times, resulting in a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 4620.0
Deduct 0 from 49 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 7:
490 divided by 54 is 9 with a remainder of 4.
The next digit of our result is 9. 
Result so far: 4620.9
Subtract 486 from 490 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
When dividing 40 by 54, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 4620.9
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
The number 54 fits into 400 7 times, leaving a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 4620.907
The remainder is 22 after subtracting 378 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 10:
54 goes into 220 4 times with a remainder of 4.
The next digit of our result is 4. 
Result so far: 4620.9074
Deduct 216 from 220 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 11:
54 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 4620.9074
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
The number 54 fits into 400 7 times, leaving a remainder of 22.
Write down 7 as next digit of the result. 
Result so far: 4620.907407
The remainder is 22 after subtracting 378 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 13:
54 goes into 220 4 times with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 4620.9074074
Subtract 216 from 220 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 14:
54 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 4620.9074074
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 4620.9074074 with a remaining 4e-08.
