298490 ÷ 18 
We want to figure out the number of times 298490 can be divided by 18.

On to step 1:
The number 18 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 18

Let's proceed to step 2:
The number 18 fits into 29 1 times, leaving a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 18 from 29 and we're left with 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 18

Going ahead to step 3:
18 goes into 118 6 times with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 16.0
The remainder is 10 after subtracting 108 from 118.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 18

Step 4:
104 divided by 18 is 5 with a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 165.0
If we take 90 away from 104, we end up with 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 18

Moving on to step 5:
18 can be fit into 149 8 times, resulting in a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 1658.0
Deduct 144 from 149 and we're left with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 18

Let's proceed to step 6:
18 can be fit into 50 2 times, resulting in a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 16582.0
If we take 36 away from 50, we end up 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 7:
18 goes into 140 7 times with a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 16582.7
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.

Step 8:
The number 18 fits into 140 7 times, leaving a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 16582.77
The remainder is 14 after subtracting 126 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 16582.77 with a remaining 0.014.
