We're dividing 441270 by 54 
The aim is to understand the frequency of 54 in 441270.

Advancing to step 1:
When dividing 4 by 54, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 54

Advancing to step 2:
When dividing 44 by 54, we get 0 with a remainder of 44.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 44 after subtracting 0 from 44.
Take the next digit (1) from the dividend and append it to 44, then repeat: 441 / 54

Step 3:
54 can be fit into 441 8 times, resulting in a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 432 from 441 to get 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 54

On to step 4:
The number 54 fits into 92 1 times, leaving a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 81.0
If we subtract 54 from 92, we get 38.
Take the next digit (7) from the dividend and append it to 38, then repeat: 387 / 54

On to step 5:
When dividing 387 by 54, we get 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 817.0
Subtract 378 from 387 to get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 54

Step 6:
If we divide 90 by 54, we get 1 and a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 8171.0
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.

Going ahead to step 7:
When dividing 360 by 54, we get 6 with a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 8171.6
Deduct 324 from 360 and we're left 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.

Going ahead to step 8:
54 can be fit into 360 6 times, resulting in a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 8171.66
Subtracting 324 from 360 leaves us 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 outcome is 8171.66, with a leftover of 0.036.
