Let's divide 27021 by 27
The aim is to understand the frequency of 27 in 27021.

Moving on to step 1:
27 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 27

Going ahead to step 2:
If we divide 27 by 27, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 27 from 27 and we're left with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 27

Moving on to step 3:
The number 27 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 0 to get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 27

Moving on to step 4:
The number 27 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 100.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 27

Going ahead to step 5:
When dividing 21 by 27, we get 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 1000.0
If we subtract 0 from 21, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 6:
210 divided by 27 is 7 with a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 1000.7
If we take 189 away from 210, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 7:
When dividing 210 by 27, we get 7 with a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 1000.77
Subtract 189 from 210 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

After the division, we end up with 1000.77 and a remainder of 0.021.
