355707 ÷ 27 
The aim is to understand the frequency of 27 in 355707.

Step 1:
27 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 27

Step 2:
27 goes into 35 1 times with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 27 from 35, we get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 27

Going ahead to step 3:
27 goes into 85 3 times with a remainder of 4.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 81 from 85 leaves us with 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 27

Moving on to step 4:
27 goes into 47 1 times with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 131.0
Subtract 27 from 47 to get 20.
Take the next digit (0) from the dividend and append it to 20, then repeat: 200 / 27

Going ahead to step 5:
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: 1317.0
If we subtract 189 from 200, we get 11.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 27

Moving on to step 6:
The number 27 fits into 117 4 times, leaving a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 13174.0
The remainder is 9 after subtracting 108 from 117.
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:
If we divide 90 by 27, we get 3 and a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 13174.3
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.

Step 8:
27 goes into 90 3 times with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 13174.33
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.

Our division results in 13174.33 with a remaining 0.009.
