We're dividing 571488 by 54 
The aim is to understand the frequency of 54 in 571488.

Let's proceed to step 1:
The number 54 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 54

Step 2:
57 divided by 54 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 3 after subtracting 54 from 57.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 54

Step 3:
If we divide 31 by 54, we get 0 and a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 31, we get 31.
Grab the next digit (4) from the dividend, add it to 31, then carry on: 314 / 54

On to step 4:
54 can be fit into 314 5 times, resulting in a remainder of 44.
Write down 5 as next digit of the result. 
Result so far: 105.0
Subtract 270 from 314 to get 44.
Fetch the next digit (8) from the dividend, attach it to 44 and continue: 448 / 54

Step 5:
54 can be fit into 448 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 1058.0
Deduct 432 from 448 and we're left with 16.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 54

Step 6:
The number 54 fits into 168 3 times, leaving a remainder of 6.
The next digit of our result is 3. 
Result so far: 10583.0
If we take 162 away from 168, we end up 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.

Advancing to step 7:
54 can be fit into 60 1 times, resulting in a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 10583.1
The remainder is 6 after subtracting 54 from 60.
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:
54 goes into 60 1 times with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 10583.11
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 quotient of the division is 10583.11, and the remainder is 0.006.
