489855 ÷ 27 
Our goal is to divide 489855 by 27.

Let's proceed to step 1:
If we divide 4 by 27, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 27

On to step 2:
When dividing 48 by 27, we get 1 with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 27 from 48 leaves us with 21.
Include the next digit (9) from the dividend after 21, then repeat: 219 / 27

Going ahead to step 3:
27 goes into 219 8 times with a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 18.0
The remainder is 3 after subtracting 216 from 219.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 27

Moving on to step 4:
If we divide 38 by 27, we get 1 and a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 181.0
Deduct 27 from 38 and we're left with 11.
Bring next digit (5) of the dividend behind the 11 and repeat the process: 115 / 27

Let's proceed to step 5:
When dividing 115 by 27, we get 4 with a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 1814.0
Deduct 108 from 115 and we're left with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 27

Step 6:
75 divided by 27 is 2 with a remainder of 21.
Record the quotient 2 as the next digit in the result. 
Result so far: 18142.0
If we subtract 54 from 75, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
When dividing 210 by 27, we get 7 with a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 18142.7
Deduct 189 from 210 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 8:
The number 27 fits into 210 7 times, leaving a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 18142.77
Subtract 189 from 210 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final outcome is 18142.77, with a leftover of 0.021.
