We're dividing 455532 by 54 
The aim is to understand the frequency of 54 in 455532.

On to step 1:
If we divide 4 by 54, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 54

Going ahead to step 2:
54 can be fit into 45 0 times, resulting in a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Bring next digit (5) of the dividend behind the 45 and repeat the process: 455 / 54

Advancing to step 3:
54 goes into 455 8 times with a remainder of 23.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 432 from 455, we get 23.
Take the next digit (5) from the dividend and append it to 23, then repeat: 235 / 54

Let's proceed to step 4:
When dividing 235 by 54, we get 4 with a remainder of 19.
Write down 4 as next digit of the result. 
Result so far: 84.0
Deduct 216 from 235 and we're left with 19.
Grab the next digit (3) from the dividend, add it to 19, then carry on: 193 / 54

Advancing to step 5:
54 goes into 193 3 times with a remainder of 31.
Record the quotient 3 as the next digit in the result. 
Result so far: 843.0
The remainder is 31 after subtracting 162 from 193.
Bring next digit (2) of the dividend behind the 31 and repeat the process: 312 / 54

On to step 6:
When dividing 312 by 54, we get 5 with a remainder of 42.
Write down 5 as next digit of the result. 
Result so far: 8435.0
If we take 270 away from 312, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 7:
If we divide 420 by 54, we get 7 and a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 8435.7
Deduct 378 from 420 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 8:
54 goes into 420 7 times with a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 8435.77
If we subtract 378 from 420, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Our division results in 8435.77 with a remaining 0.042.
