We look at the division of 488678 by 18 
Our goal is to divide 488678 by 18.

Advancing to step 1:
4 divided by 18 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 18

Step 2:
48 divided by 18 is 2 with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 12 after subtracting 36 from 48.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 18

Let's proceed to step 3:
18 goes into 128 7 times with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
If we take 126 away from 128, we end up with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 18

Moving on to step 4:
If we divide 26 by 18, we get 1 and a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 271.0
If we subtract 18 from 26, we get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 18

Step 5:
18 goes into 87 4 times with a remainder of 15.
Record the quotient 4 as the next digit in the result. 
Result so far: 2714.0
The remainder is 15 after subtracting 72 from 87.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 18

Step 6:
18 can be fit into 158 8 times, resulting in a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 27148.0
Subtract 144 from 158 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
18 can be fit into 140 7 times, resulting in a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 27148.7
Subtracting 126 from 140 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
18 goes into 140 7 times with a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 27148.77
Subtract 126 from 140 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 27148.77 with a remainder of 0.014.
