We look at the division of 18126566 by 54 
The aim is to understand the frequency of 54 in 18126566.

Going ahead to step 1:
If we divide 1 by 54, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 54

Moving on to step 2:
54 goes into 18 0 times with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 54

Moving on to step 3:
When dividing 181 by 54, we get 3 with a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 162 from 181 leaves us with 19.
Bring next digit (2) of the dividend behind the 19 and repeat the process: 192 / 54

Let's proceed to step 4:
54 goes into 192 3 times with a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 33.0
Subtracting 162 from 192 leaves us with 30.
Append the next digit (6) from the dividend to 30 and continue with: 306 / 54

Let's proceed to step 5:
If we divide 306 by 54, we get 5 and a remainder of 36.
The next digit of our result is 5. 
Result so far: 335.0
If we subtract 270 from 306, we get 36.
Take the next digit (5) from the dividend and append it to 36, then repeat: 365 / 54

Going ahead to step 6:
54 can be fit into 365 6 times, resulting in a remainder of 41.
The number 6 becomes the next digit in our result. 
Result so far: 3356.0
Subtract 324 from 365 to get 41.
Fetch the next digit (6) from the dividend, attach it to 41 and continue: 416 / 54

Moving on to step 7:
If we divide 416 by 54, we get 7 and a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 33567.0
If we take 378 away from 416, we end up with 38.
Fetch the next digit (6) from the dividend, attach it to 38 and continue: 386 / 54

Moving on to step 8:
54 can be fit into 386 7 times, resulting in a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 335677.0
Subtracting 378 from 386 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
54 can be fit into 80 1 times, resulting in a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 335677.1
If we subtract 54 from 80, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 10:
If we divide 260 by 54, we get 4 and a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 335677.14
Subtracting 216 from 260 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 11:
The number 54 fits into 440 8 times, leaving a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 335677.148
Subtract 432 from 440 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 12:
If we divide 80 by 54, we get 1 and a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 335677.1481
Subtract 54 from 80 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 13:
54 can be fit into 260 4 times, resulting in a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 335677.14814
Deduct 216 from 260 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 14:
440 divided by 54 is 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 335677.148148
If we subtract 432 from 440, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 15:
80 divided by 54 is 1 with a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 335677.1481481
If we take 54 away from 80, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 16:
The number 54 fits into 260 4 times, leaving a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 335677.14814814
Subtracting 216 from 260 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

In conclusion, the division gives 335677.14814814 with a balance of 4.4e-08.
