302904 divided by 54 
The aim is to understand the frequency of 54 in 302904.

Moving on to step 1:
54 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 54

On to step 2:
30 divided by 54 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Include the next digit (2) from the dividend after 30, then repeat: 302 / 54

Moving on to step 3:
If we divide 302 by 54, we get 5 and a remainder of 32.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 270 from 302 leaves us with 32.
Bring next digit (9) of the dividend behind the 32 and repeat the process: 329 / 54

Advancing to step 4:
If we divide 329 by 54, we get 6 and a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 56.0
Deduct 324 from 329 and we're left with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 54

Moving on to step 5:
When dividing 50 by 54, we get 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 560.0
The remainder is 50 after subtracting 0 from 50.
Fetch the next digit (4) from the dividend, attach it to 50 and continue: 504 / 54

On to step 6:
If we divide 504 by 54, we get 9 and a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 5609.0
If we take 486 away from 504, we end up with 18.
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 7:
54 goes into 180 3 times with a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 5609.3
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.

Going ahead to step 8:
54 goes into 180 3 times with a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 5609.33
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 5609.33 and a remainder of 0.018.
