915258 ÷ 27 
The aim is to understand the frequency of 27 in 915258.

Let's proceed to step 1:
9 divided by 27 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 27

Step 2:
27 can be fit into 91 3 times, resulting in a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 81 from 91, we get 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 27

Moving on to step 3:
When dividing 105 by 27, we get 3 with a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Deduct 81 from 105 and we're left with 24.
Bring next digit (2) of the dividend behind the 24 and repeat the process: 242 / 27

On to step 4:
27 can be fit into 242 8 times, resulting in a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 338.0
If we take 216 away from 242, we end up with 26.
Append the next digit (5) from the dividend to 26 and continue with: 265 / 27

Step 5:
27 can be fit into 265 9 times, resulting in a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 3389.0
Deduct 243 from 265 and we're left with 22.
Bring next digit (8) of the dividend behind the 22 and repeat the process: 228 / 27

On to step 6:
When dividing 228 by 27, we get 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 33898.0
If we take 216 away from 228, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
If we divide 120 by 27, we get 4 and a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 33898.4
Deduct 108 from 120 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
27 goes into 120 4 times with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 33898.44
If we take 108 away from 120, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 33898.44 and a remainder of 0.012.
