16125 ÷ 27 
The aim is to understand the frequency of 27 in 16125.

Going ahead to step 1:
27 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 27

On to step 2:
The number 27 fits into 16 0 times, leaving a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 27

Advancing to step 3:
161 divided by 27 is 5 with a remainder of 26.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 26 after subtracting 135 from 161.
Include the next digit (2) from the dividend after 26, then repeat: 262 / 27

Moving on to step 4:
If we divide 262 by 27, we get 9 and a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 59.0
If we take 243 away from 262, we end up with 19.
Include the next digit (5) from the dividend after 19, then repeat: 195 / 27

Moving on to step 5:
When dividing 195 by 27, we get 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 597.0
Subtract 189 from 195 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 6:
27 goes into 60 2 times with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 597.2
The remainder is 6 after subtracting 54 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
If we divide 60 by 27, we get 2 and a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 597.22
If we take 54 away from 60, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 597.22 and a remainder of 0.006.
