We're dividing 54972 by 18 
The aim is to understand the frequency of 18 in 54972.

On to step 1:
When dividing 5 by 18, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 18

Moving on to step 2:
When dividing 54 by 18, we get 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 0 after subtracting 54 from 54.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 18

Advancing to step 3:
18 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 30.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 18

Advancing to step 4:
When dividing 97 by 18, we get 5 with a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 305.0
Subtract 90 from 97 to get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 18

Let's proceed to step 5:
72 divided by 18 is 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 3054.0
Subtract 72 from 72 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.

Moving on to step 6:
18 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 3054.0
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.

Moving on to step 7:
If we divide 0 by 18, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3054.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 3054.0 with a remaining 0.0.
