Let's divide 72184815 by 54
The aim is to understand the frequency of 54 in 72184815.

Let's proceed to step 1:
When dividing 7 by 54, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 54

Moving on to step 2:
54 can be fit into 72 1 times, resulting in a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 54 from 72, we get 18.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 54

Going ahead to step 3:
54 goes into 181 3 times with a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 19 after subtracting 162 from 181.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 54

Advancing to step 4:
The number 54 fits into 198 3 times, leaving a remainder of 36.
The next digit of our result is 3. 
Result so far: 133.0
Subtracting 162 from 198 leaves us with 36.
Bring next digit (4) of the dividend behind the 36 and repeat the process: 364 / 54

Advancing to step 5:
54 goes into 364 6 times with a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 1336.0
If we take 324 away from 364, we end up with 40.
Grab the next digit (8) from the dividend, add it to 40, then carry on: 408 / 54

Moving on to step 6:
When dividing 408 by 54, we get 7 with a remainder of 30.
Record the quotient 7 as the next digit in the result. 
Result so far: 13367.0
Subtracting 378 from 408 leaves us with 30.
Fetch the next digit (1) from the dividend, attach it to 30 and continue: 301 / 54

Step 7:
301 divided by 54 is 5 with a remainder of 31.
The next digit of our result is 5. 
Result so far: 133675.0
If we subtract 270 from 301, we get 31.
Append the next digit (5) from the dividend to 31 and continue with: 315 / 54

Step 8:
54 can be fit into 315 5 times, resulting in a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 1336755.0
The remainder is 45 after subtracting 270 from 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 9:
The number 54 fits into 450 8 times, leaving a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 1336755.8
The remainder is 18 after subtracting 432 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 10:
54 goes into 180 3 times with a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 1336755.83
Subtract 162 from 180 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 11:
54 goes into 180 3 times with a remainder of 18.
The next digit of our result is 3. 
Result so far: 1336755.833
If we subtract 162 from 180, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 1336755.833 and a remainder of 0.0018.
