We look at the division of 648879 by 27 
The aim is to understand the frequency of 27 in 648879.

Let's proceed to step 1:
6 divided by 27 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 27

Advancing to step 2:
The number 27 fits into 64 2 times, leaving a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 54 from 64 leaves us with 10.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 27

On to step 3:
27 goes into 108 4 times with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
The remainder is 0 after subtracting 108 from 108.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 27

On to step 4:
27 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 240.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 27

Let's proceed to step 5:
27 can be fit into 87 3 times, resulting in a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 2403.0
If we subtract 81 from 87, we get 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 27

On to step 6:
When dividing 69 by 27, we get 2 with a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 24032.0
Subtracting 54 from 69 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
The number 27 fits into 150 5 times, leaving a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 24032.5
Deduct 135 from 150 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 8:
When dividing 150 by 27, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 24032.55
Deduct 135 from 150 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 24032.55, with a leftover of 0.015.
