We're dividing 557433 by 54 
The aim is to understand the frequency of 54 in 557433.

Advancing to step 1:
54 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 54

Moving on to step 2:
When dividing 55 by 54, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 1 after subtracting 54 from 55.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 54

Going ahead to step 3:
54 can be fit into 17 0 times, resulting in a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 17 and we're left with 17.
Grab the next digit (4) from the dividend, add it to 17, then carry on: 174 / 54

Moving on to step 4:
54 goes into 174 3 times with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 103.0
The remainder is 12 after subtracting 162 from 174.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 54

On to step 5:
The number 54 fits into 123 2 times, leaving a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 1032.0
Subtract 108 from 123 to get 15.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 54

Advancing to step 6:
If we divide 153 by 54, we get 2 and a remainder of 45.
Write down 2 as next digit of the result. 
Result so far: 10322.0
The remainder is 45 after subtracting 108 from 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 7:
54 goes into 450 8 times with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 10322.8
Subtract 432 from 450 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.

On to step 8:
If we divide 180 by 54, we get 3 and a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 10322.83
The remainder is 18 after subtracting 162 from 180.
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 9:
When dividing 180 by 54, we get 3 with a remainder of 18.
The next digit of our result is 3. 
Result so far: 10322.833
Deduct 162 from 180 and we're left 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.

The quotient of the division is 10322.833, and the remainder is 0.0018.
