Let's divide 630978 by 27
The aim is to understand the frequency of 27 in 630978.

Step 1:
27 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 27

Moving on to step 2:
27 can be fit into 63 2 times, resulting in a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 54 away from 63, we end up with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 27

On to step 3:
27 goes into 90 3 times with a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 23.0
The remainder is 9 after subtracting 81 from 90.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 27

Step 4:
If we divide 99 by 27, we get 3 and a remainder of 18.
The next digit of our result is 3. 
Result so far: 233.0
If we take 81 away from 99, we end up with 18.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 27

Let's proceed to step 5:
27 goes into 187 6 times with a remainder of 25.
The next digit of our result is 6. 
Result so far: 2336.0
If we subtract 162 from 187, we get 25.
Bring next digit (8) of the dividend behind the 25 and repeat the process: 258 / 27

Let's proceed to step 6:
If we divide 258 by 27, we get 9 and a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 23369.0
If we subtract 243 from 258, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
If we divide 150 by 27, we get 5 and a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 23369.5
Subtract 135 from 150 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
When dividing 150 by 27, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 23369.55
Deduct 135 from 150 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 23369.55 with a remaining 0.015.
