We're dividing 640746 by 27 
The aim is to understand the frequency of 27 in 640746.

Step 1:
27 can be fit into 6 0 times, resulting in 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.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 27

Advancing to step 2:
When dividing 64 by 27, we get 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 54 from 64, we get 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 27

Going ahead to step 3:
If we divide 100 by 27, we get 3 and a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtract 81 from 100 to get 19.
Include the next digit (7) from the dividend after 19, then repeat: 197 / 27

Step 4:
197 divided by 27 is 7 with a remainder of 8.
The next digit of our result is 7. 
Result so far: 237.0
Subtract 189 from 197 to get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 27

On to step 5:
The number 27 fits into 84 3 times, leaving a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 2373.0
Subtract 81 from 84 to get 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 27

On to step 6:
The number 27 fits into 36 1 times, leaving a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 23731.0
If we take 27 away from 36, we end up 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 7:
When dividing 90 by 27, we get 3 with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 23731.3
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.

Step 8:
If we divide 90 by 27, we get 3 and a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 23731.33
If we take 81 away from 90, we end up 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.

The quotient of the division is 23731.33, and the remainder is 0.009.
