We look at the division of 210935 by 27 
The aim is to understand the frequency of 27 in 210935.

Step 1:
27 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 27

Step 2:
27 can be fit into 21 0 times, resulting in a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 27

Going ahead to step 3:
When dividing 210 by 27, we get 7 with a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 21 after subtracting 189 from 210.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 27

Step 4:
The number 27 fits into 219 8 times, leaving a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 78.0
The remainder is 3 after subtracting 216 from 219.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 27

Moving on to step 5:
The number 27 fits into 33 1 times, leaving a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 781.0
Deduct 27 from 33 and we're left with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 27

Advancing to step 6:
27 goes into 65 2 times with a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 7812.0
Subtracting 54 from 65 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
When dividing 110 by 27, we get 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 7812.4
Deduct 108 from 110 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
If we divide 20 by 27, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 7812.4
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
When dividing 200 by 27, we get 7 with a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 7812.407
Subtracting 189 from 200 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 10:
The number 27 fits into 110 4 times, leaving a remainder of 2.
The next digit of our result is 4. 
Result so far: 7812.4074
If we subtract 108 from 110, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 11:
When dividing 20 by 27, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 7812.4074
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
If we divide 200 by 27, we get 7 and a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 7812.407407
Subtracting 189 from 200 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 13:
110 divided by 27 is 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 7812.4074074
If we subtract 108 from 110, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 14:
20 divided by 27 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 7812.4074074
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 7812.4074074 and a remainder of 2e-08.
