We look at the division of 634833 by 27 
The aim is to understand the frequency of 27 in 634833.

Step 1:
6 divided by 27 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 27

On to step 2:
If we divide 63 by 27, we get 2 and a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 54 from 63 to get 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 27

Let's proceed to step 3:
27 goes into 94 3 times with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtract 81 from 94 to get 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 27

Moving on to step 4:
138 divided by 27 is 5 with a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 235.0
Subtracting 135 from 138 leaves us with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 27

Advancing to step 5:
The number 27 fits into 33 1 times, leaving a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 2351.0
If we take 27 away from 33, we end up with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 27

Step 6:
63 divided by 27 is 2 with a remainder of 9.
The next digit of our result is 2. 
Result so far: 23512.0
Deduct 54 from 63 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.

On to step 7:
27 goes into 90 3 times with a remainder of 9.
The next digit of our result is 3. 
Result so far: 23512.3
If we subtract 81 from 90, we 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.

On to step 8:
The number 27 fits into 90 3 times, leaving a remainder of 9.
The next digit of our result is 3. 
Result so far: 23512.33
The remainder is 9 after subtracting 81 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The quotient of the division is 23512.33, and the remainder is 0.009.
