480290 ÷ 18 
Our goal is to divide 480290 by 18.

Moving on to step 1:
18 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 18

Moving on to step 2:
18 goes into 48 2 times with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 12 after subtracting 36 from 48.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 18

Let's proceed to step 3:
If we divide 120 by 18, we get 6 and a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
If we take 108 away from 120, we end up with 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 18

On to step 4:
When dividing 122 by 18, we get 6 with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 266.0
Subtracting 108 from 122 leaves us with 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 18

Advancing to step 5:
149 divided by 18 is 8 with a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 2668.0
The remainder is 5 after subtracting 144 from 149.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 18

Moving on to step 6:
50 divided by 18 is 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 26682.0
Subtract 36 from 50 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.

Moving on to step 7:
18 can be fit into 140 7 times, resulting in a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 26682.7
If we subtract 126 from 140, we 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.

Step 8:
18 can be fit into 140 7 times, resulting in a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 26682.77
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.

The final result is 26682.77 with a remainder of 0.014.
