427689 divided by 27 
The aim is to understand the frequency of 27 in 427689.

On to step 1:
27 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 27

On to step 2:
If we divide 42 by 27, we get 1 and a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 27 away from 42, we end up with 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 27

Going ahead to step 3:
When dividing 157 by 27, we get 5 with a remainder of 22.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 135 from 157 and we're left with 22.
Include the next digit (6) from the dividend after 22, then repeat: 226 / 27

Advancing to step 4:
27 goes into 226 8 times with a remainder of 10.
The next digit of our result is 8. 
Result so far: 158.0
The remainder is 10 after subtracting 216 from 226.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 27

Advancing to step 5:
If we divide 108 by 27, we get 4 and a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 1584.0
Subtract 108 from 108 to get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 27

On to step 6:
27 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 15840.0
Subtracting 0 from 9 leaves us 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.

Advancing to step 7:
27 can be fit into 90 3 times, resulting in a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 15840.3
Subtract 81 from 90 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.

Let's proceed to step 8:
27 can be fit into 90 3 times, resulting in a remainder of 9.
The next digit of our result is 3. 
Result so far: 15840.33
Deduct 81 from 90 and we're left 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.

After the division, we end up with 15840.33 and a remainder of 0.009.
