18660 divided by 27 
The aim is to understand the frequency of 27 in 18660.

Moving on to step 1:
If we divide 1 by 27, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 27

On to step 2:
18 divided by 27 is 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 27

Let's proceed to step 3:
If we divide 186 by 27, we get 6 and a remainder of 24.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 162 from 186, we get 24.
Grab the next digit (6) from the dividend, add it to 24, then carry on: 246 / 27

Step 4:
If we divide 246 by 27, we get 9 and a remainder of 3.
The next digit of our result is 9. 
Result so far: 69.0
Subtracting 243 from 246 leaves us with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 27

Moving on to step 5:
27 goes into 30 1 times with a remainder of 3.
The next digit of our result is 1. 
Result so far: 691.0
Deduct 27 from 30 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 6:
30 divided by 27 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 691.1
Subtract 27 from 30 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
27 can be fit into 30 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 691.11
If we take 27 away from 30, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

In conclusion, the division gives 691.11 with a balance of 0.003.
