We're dividing 279276 by 54 
The aim is to understand the frequency of 54 in 279276.

Step 1:
54 can be fit into 2 0 times, resulting in 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 (7) from the dividend, attach it to 2 and continue: 27 / 54

Step 2:
54 goes into 27 0 times with a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 27, we get 27.
Fetch the next digit (9) from the dividend, attach it to 27 and continue: 279 / 54

On to step 3:
If we divide 279 by 54, we get 5 and a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 270 from 279 leaves us with 9.
Bring next digit (2) of the dividend behind the 9 and repeat the process: 92 / 54

Going ahead to step 4:
The number 54 fits into 92 1 times, leaving a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 51.0
The remainder is 38 after subtracting 54 from 92.
Take the next digit (7) from the dividend and append it to 38, then repeat: 387 / 54

Going ahead to step 5:
54 goes into 387 7 times with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 517.0
Subtracting 378 from 387 leaves us with 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 54

On to step 6:
If we divide 96 by 54, we get 1 and a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 5171.0
Subtract 54 from 96 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 7:
When dividing 420 by 54, we get 7 with a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 5171.7
If we take 378 away from 420, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 8:
420 divided by 54 is 7 with a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 5171.77
Subtract 378 from 420 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 5171.77, with a leftover of 0.042.
