We divide 903072 by 54
The aim is to understand the frequency of 54 in 903072.

Let's proceed to step 1:
54 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 54

Going ahead to step 2:
90 divided by 54 is 1 with a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 54 from 90 leaves us with 36.
Bring next digit (3) of the dividend behind the 36 and repeat the process: 363 / 54

Advancing to step 3:
54 can be fit into 363 6 times, resulting in a remainder of 39.
Put 6 as the next digit of the answer. 
Result so far: 16.0
The remainder is 39 after subtracting 324 from 363.
Take the next digit (0) from the dividend and append it to 39, then repeat: 390 / 54

Advancing to step 4:
390 divided by 54 is 7 with a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 167.0
Deduct 378 from 390 and we're left with 12.
Bring next digit (7) of the dividend behind the 12 and repeat the process: 127 / 54

On to step 5:
The number 54 fits into 127 2 times, leaving a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 1672.0
Deduct 108 from 127 and we're left with 19.
Append the next digit (2) from the dividend to 19 and continue with: 192 / 54

Going ahead to step 6:
54 goes into 192 3 times with a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 16723.0
Deduct 162 from 192 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 7:
If we divide 300 by 54, we get 5 and a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 16723.5
If we subtract 270 from 300, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
When dividing 300 by 54, we get 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 16723.55
Subtract 270 from 300 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 16723.55 and a remainder of 0.03.
