We look at the division of 248343 by 27 
The aim is to understand the frequency of 27 in 248343.

On to step 1:
If we divide 2 by 27, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 27

Let's proceed to step 2:
If we divide 24 by 27, we get 0 and a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 24 to get 24.
Take the next digit (8) from the dividend and append it to 24, then repeat: 248 / 27

On to step 3:
The number 27 fits into 248 9 times, leaving a remainder of 5.
The next digit of our result is 9. 
Result so far: 9.0
If we take 243 away from 248, we end up with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 27

Advancing to step 4:
27 can be fit into 53 1 times, resulting in a remainder of 26.
The next digit of our result is 1. 
Result so far: 91.0
Deduct 27 from 53 and we're left with 26.
Take the next digit (4) from the dividend and append it to 26, then repeat: 264 / 27

Going ahead to step 5:
If we divide 264 by 27, we get 9 and a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 919.0
If we subtract 243 from 264, we get 21.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 27

Advancing to step 6:
27 can be fit into 213 7 times, resulting in a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 9197.0
If we subtract 189 from 213, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 7:
27 can be fit into 240 8 times, resulting in a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 9197.8
The remainder is 24 after subtracting 216 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 8:
If we divide 240 by 27, we get 8 and a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 9197.88
Deduct 216 from 240 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 9197.88 with a remaining 0.024.
