We look at the division of 545568 by 27 
The aim is to understand the frequency of 27 in 545568.

Step 1:
When dividing 5 by 27, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 27

Let's proceed to step 2:
The number 27 fits into 54 2 times, leaving a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 54 from 54, we get 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 27

Moving on to step 3:
27 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 20.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 27

Advancing to step 4:
The number 27 fits into 55 2 times, leaving a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 202.0
If we subtract 54 from 55, we get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 27

Advancing to step 5:
The number 27 fits into 16 0 times, leaving a remainder of 16.
The next digit of our result is 0. 
Result so far: 2020.0
The remainder is 16 after subtracting 0 from 16.
Grab the next digit (8) from the dividend, add it to 16, then carry on: 168 / 27

Moving on to step 6:
If we divide 168 by 27, we get 6 and a remainder of 6.
The next digit of our result is 6. 
Result so far: 20206.0
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:
60 divided by 27 is 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 20206.2
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:
When dividing 60 by 27, we get 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 20206.22
If we subtract 54 from 60, we 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 20206.22, with a leftover of 0.006.
