We look at the division of 205419 by 27 
The aim is to understand the frequency of 27 in 205419.

Let's proceed to step 1:
When dividing 2 by 27, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 27

On to step 2:
27 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Take the next digit (5) from the dividend and append it to 20, then repeat: 205 / 27

Let's proceed to step 3:
The number 27 fits into 205 7 times, leaving a remainder of 16.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 16 after subtracting 189 from 205.
Bring next digit (4) of the dividend behind the 16 and repeat the process: 164 / 27

Advancing to step 4:
27 goes into 164 6 times with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 76.0
If we subtract 162 from 164, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 27

Moving on to step 5:
27 can be fit into 21 0 times, resulting in a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 760.0
Deduct 0 from 21 and we're left with 21.
Take the next digit (9) from the dividend and append it to 21, then repeat: 219 / 27

Going ahead to step 6:
27 can be fit into 219 8 times, resulting in a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 7608.0
Subtract 216 from 219 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
27 can be fit into 30 1 times, resulting in a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 7608.1
Subtracting 27 from 30 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 8:
If we divide 30 by 27, we get 1 and a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 7608.11
If we subtract 27 from 30, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

After the division, we end up with 7608.11 and a remainder of 0.003.
