We divide 266688 by 27
The aim is to understand the frequency of 27 in 266688.

Let's proceed to step 1:
If we divide 2 by 27, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 27

Step 2:
27 goes into 26 0 times with a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 26 and we're left with 26.
Bring next digit (6) of the dividend behind the 26 and repeat the process: 266 / 27

Step 3:
When dividing 266 by 27, we get 9 with a remainder of 23.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 243 from 266 to get 23.
Include the next digit (6) from the dividend after 23, then repeat: 236 / 27

Moving on to step 4:
If we divide 236 by 27, we get 8 and a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 98.0
Deduct 216 from 236 and we're left with 20.
Fetch the next digit (8) from the dividend, attach it to 20 and continue: 208 / 27

On to step 5:
27 goes into 208 7 times with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 987.0
Subtract 189 from 208 to get 19.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 27

Step 6:
If we divide 198 by 27, we get 7 and a remainder of 9.
The next digit of our result is 7. 
Result so far: 9877.0
If we subtract 189 from 198, 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 7:
27 can be fit into 90 3 times, resulting in a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 9877.3
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.

Moving on to step 8:
90 divided by 27 is 3 with a remainder of 9.
The next digit of our result is 3. 
Result so far: 9877.33
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 final outcome is 9877.33, with a leftover of 0.009.
