We're dividing 72045 by 54 
The aim is to understand the frequency of 54 in 72045.

Let's proceed to step 1:
54 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 54

Moving on to step 2:
When dividing 72 by 54, we get 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 54 from 72 leaves us with 18.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 54

Going ahead to step 3:
When dividing 180 by 54, we get 3 with a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 18 after subtracting 162 from 180.
Take the next digit (4) from the dividend and append it to 18, then repeat: 184 / 54

Step 4:
The number 54 fits into 184 3 times, leaving a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 133.0
The remainder is 22 after subtracting 162 from 184.
Include the next digit (5) from the dividend after 22, then repeat: 225 / 54

Going ahead to step 5:
If we divide 225 by 54, we get 4 and a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 1334.0
Subtracting 216 from 225 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 6:
When dividing 90 by 54, we get 1 with a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 1334.1
If we take 54 away from 90, 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.

On to step 7:
When dividing 360 by 54, we get 6 with a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 1334.16
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.

Moving on to step 8:
If we divide 360 by 54, we get 6 and a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 1334.166
If we take 324 away from 360, 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.

The final result is 1334.166 with a remainder of 0.0036.
