254390 ÷ 18 
We want to divide 254390 by 18.

Moving on to step 1:
2 divided by 18 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 18

On to step 2:
The number 18 fits into 25 1 times, leaving a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 7 after subtracting 18 from 25.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 18

On to step 3:
18 goes into 74 4 times with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtract 72 from 74 to get 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 18

Advancing to step 4:
The number 18 fits into 23 1 times, leaving a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 141.0
If we subtract 18 from 23, we get 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 18

Advancing to step 5:
If we divide 59 by 18, we get 3 and a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 1413.0
Deduct 54 from 59 and we're left with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 18

Going ahead to step 6:
When dividing 50 by 18, we get 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 14132.0
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.

Step 7:
When dividing 140 by 18, we get 7 with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 14132.7
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.

On to step 8:
When dividing 140 by 18, we get 7 with a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 14132.77
Deduct 126 from 140 and we're left 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.

After the division, we end up with 14132.77 and a remainder of 0.014.
