509955 ÷ 27 
We want to figure out the number of times 509955 can be divided by 27.

Moving on to step 1:
5 divided by 27 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 27

Moving on to step 2:
27 goes into 50 1 times with a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 27 from 50 leaves us with 23.
Take the next digit (9) from the dividend and append it to 23, then repeat: 239 / 27

Moving on to step 3:
239 divided by 27 is 8 with a remainder of 23.
The next digit of our result is 8. 
Result so far: 18.0
Deduct 216 from 239 and we're left with 23.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 27

Advancing to step 4:
When dividing 239 by 27, we get 8 with a remainder of 23.
Record the quotient 8 as the next digit in the result. 
Result so far: 188.0
Deduct 216 from 239 and we're left with 23.
Include the next digit (5) from the dividend after 23, then repeat: 235 / 27

On to step 5:
The number 27 fits into 235 8 times, leaving a remainder of 19.
The number 8 becomes the next digit in our result. 
Result so far: 1888.0
Subtracting 216 from 235 leaves us with 19.
Grab the next digit (5) from the dividend, add it to 19, then carry on: 195 / 27

On to step 6:
When dividing 195 by 27, we get 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 18887.0
The remainder is 6 after subtracting 189 from 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
60 divided by 27 is 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 18887.2
If we take 54 away from 60, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
27 goes into 60 2 times with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 18887.22
Subtracting 54 from 60 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 18887.22 with a remainder of 0.006.
