We look at the division of 443241 by 27 
The aim is to understand the frequency of 27 in 443241.

On to step 1:
If we divide 4 by 27, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 27

Let's proceed to step 2:
27 goes into 44 1 times with a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
If we take 27 away from 44, we end up with 17.
Take the next digit (3) from the dividend and append it to 17, then repeat: 173 / 27

Moving on to step 3:
The number 27 fits into 173 6 times, leaving a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 162 away from 173, we end up with 11.
Append the next digit (2) from the dividend to 11 and continue with: 112 / 27

Step 4:
When dividing 112 by 27, we get 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 164.0
Subtract 108 from 112 to get 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 27

Moving on to step 5:
27 goes into 44 1 times with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 1641.0
The remainder is 17 after subtracting 27 from 44.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 27

Moving on to step 6:
The number 27 fits into 171 6 times, leaving a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 16416.0
Subtract 162 from 171 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
The number 27 fits into 90 3 times, leaving a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 16416.3
If we take 81 away from 90, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 8:
27 goes into 90 3 times with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 16416.33
If we take 81 away from 90, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final result is 16416.33 with a remainder of 0.009.
