We divide 628191 by 27
The aim is to understand the frequency of 27 in 628191.

Let's proceed to step 1:
27 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 27

Let's proceed to step 2:
The number 27 fits into 62 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 54 from 62, we get 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 27

Going ahead to step 3:
27 can be fit into 88 3 times, resulting in a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
The remainder is 7 after subtracting 81 from 88.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 27

Step 4:
27 goes into 71 2 times with a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 232.0
The remainder is 17 after subtracting 54 from 71.
Include the next digit (9) from the dividend after 17, then repeat: 179 / 27

On to step 5:
27 goes into 179 6 times with a remainder of 17.
The next digit of our result is 6. 
Result so far: 2326.0
If we subtract 162 from 179, we get 17.
Bring next digit (1) of the dividend behind the 17 and repeat the process: 171 / 27

On to step 6:
If we divide 171 by 27, we get 6 and a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 23266.0
Subtract 162 from 171 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.

Going ahead to step 7:
27 can be fit into 90 3 times, resulting in a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 23266.3
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.

Going ahead to step 8:
27 can be fit into 90 3 times, resulting in a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 23266.33
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.

The final outcome is 23266.33, with a leftover of 0.009.
