We look at the division of 566636 by 54 
The aim is to understand the frequency of 54 in 566636.

Moving on to step 1:
If we divide 5 by 54, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 54

Advancing to step 2:
If we divide 56 by 54, we get 1 and a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 54 from 56 leaves us with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 54

Let's proceed to step 3:
When dividing 26 by 54, we get 0 with a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 26 and we're left with 26.
Fetch the next digit (6) from the dividend, attach it to 26 and continue: 266 / 54

Step 4:
If we divide 266 by 54, we get 4 and a remainder of 50.
Write down 4 as next digit of the result. 
Result so far: 104.0
Subtracting 216 from 266 leaves us with 50.
Grab the next digit (3) from the dividend, add it to 50, then carry on: 503 / 54

Going ahead to step 5:
54 can be fit into 503 9 times, resulting in a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 1049.0
If we take 486 away from 503, we end up with 17.
Include the next digit (6) from the dividend after 17, then repeat: 176 / 54

Advancing to step 6:
54 can be fit into 176 3 times, resulting in a remainder of 14.
The next digit of our result is 3. 
Result so far: 10493.0
If we take 162 away from 176, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
The number 54 fits into 140 2 times, leaving a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 10493.2
The remainder is 32 after subtracting 108 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 8:
If we divide 320 by 54, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 10493.25
If we take 270 away from 320, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 9:
When dividing 500 by 54, we get 9 with a remainder of 14.
The next digit of our result is 9. 
Result so far: 10493.259
If we take 486 away from 500, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 10:
54 can be fit into 140 2 times, resulting in a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 10493.2592
Subtract 108 from 140 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 11:
When dividing 320 by 54, we get 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 10493.25925
Subtract 270 from 320 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 12:
When dividing 500 by 54, we get 9 with a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 10493.259259
The remainder is 14 after subtracting 486 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 13:
140 divided by 54 is 2 with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 10493.2592592
The remainder is 32 after subtracting 108 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 14:
54 can be fit into 320 5 times, resulting in a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 10493.25925925
Deduct 270 from 320 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 10493.25925925 with a remaining 5e-08.
