We look at the division of 489382 by 27 
The aim is to understand the frequency of 27 in 489382.

Step 1:
The number 27 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 27

On to step 2:
27 goes into 48 1 times with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 27 from 48 and we're left with 21.
Include the next digit (9) from the dividend after 21, then repeat: 219 / 27

On to step 3:
When dividing 219 by 27, we get 8 with a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Deduct 216 from 219 and we're left with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 27

On to step 4:
27 can be fit into 33 1 times, resulting in a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 181.0
If we subtract 27 from 33, we get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 27

Going ahead to step 5:
68 divided by 27 is 2 with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 1812.0
Subtracting 54 from 68 leaves us with 14.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 27

Let's proceed to step 6:
When dividing 142 by 27, we get 5 with a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 18125.0
Deduct 135 from 142 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
If we divide 70 by 27, we get 2 and a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 18125.2
If we subtract 54 from 70, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
27 can be fit into 160 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 18125.25
Subtracting 135 from 160 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
250 divided by 27 is 9 with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 18125.259
The remainder is 7 after subtracting 243 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 10:
When dividing 70 by 27, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 18125.2592
The remainder is 16 after subtracting 54 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
The number 27 fits into 160 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 18125.25925
The remainder is 25 after subtracting 135 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 12:
The number 27 fits into 250 9 times, leaving a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 18125.259259
Subtract 243 from 250 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 13:
27 can be fit into 70 2 times, resulting in a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 18125.2592592
The remainder is 16 after subtracting 54 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 14:
27 can be fit into 160 5 times, resulting in a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 18125.25925925
If we subtract 135 from 160, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 18125.25925925 and a remainder of 2.5e-08.
