Let's divide 567573 by 54
The aim is to understand the frequency of 54 in 567573.

Moving on to step 1:
The number 54 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 54

Moving on to step 2:
56 divided by 54 is 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 54 from 56, we get 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 54

Moving on to step 3:
54 goes into 27 0 times with a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 27 after subtracting 0 from 27.
Take the next digit (5) from the dividend and append it to 27, then repeat: 275 / 54

Let's proceed to step 4:
54 goes into 275 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 105.0
Deduct 270 from 275 and we're left with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 54

Moving on to step 5:
When dividing 57 by 54, we get 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1051.0
Deduct 54 from 57 and we're left with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 54

Advancing to step 6:
54 can be fit into 33 0 times, resulting in a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 10510.0
Subtracting 0 from 33 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 7:
The number 54 fits into 330 6 times, leaving a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 10510.6
Subtracting 324 from 330 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
If we divide 60 by 54, we get 1 and a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 10510.61
Subtracting 54 from 60 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
The number 54 fits into 60 1 times, leaving a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 10510.611
Subtract 54 from 60 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 10510.611, with a leftover of 0.0006.
