We're dividing 748368 by 54 
The aim is to understand the frequency of 54 in 748368.

On to step 1:
54 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 54

Moving on to step 2:
74 divided by 54 is 1 with a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 54 away from 74, we end up with 20.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 54

Step 3:
54 goes into 208 3 times with a remainder of 46.
The next digit of our result is 3. 
Result so far: 13.0
The remainder is 46 after subtracting 162 from 208.
Grab the next digit (3) from the dividend, add it to 46, then carry on: 463 / 54

Moving on to step 4:
If we divide 463 by 54, we get 8 and a remainder of 31.
Record the quotient 8 as the next digit in the result. 
Result so far: 138.0
Subtracting 432 from 463 leaves us with 31.
Append the next digit (6) from the dividend to 31 and continue with: 316 / 54

Going ahead to step 5:
54 goes into 316 5 times with a remainder of 46.
Put 5 as the next digit of the answer. 
Result so far: 1385.0
Subtract 270 from 316 to get 46.
Take the next digit (8) from the dividend and append it to 46, then repeat: 468 / 54

Advancing to step 6:
54 goes into 468 8 times with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 13858.0
If we take 432 away from 468, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 7:
The number 54 fits into 360 6 times, leaving a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 13858.6
Subtract 324 from 360 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 8:
360 divided by 54 is 6 with a remainder of 36.
The next digit of our result is 6. 
Result so far: 13858.66
If we subtract 324 from 360, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Our division results in 13858.66 with a remaining 0.036.
