998418 ÷ 18 
Let's see how many times 18 fits into 998418.

Advancing to step 1:
18 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 18

Advancing to step 2:
99 divided by 18 is 5 with a remainder of 9.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 90 from 99 to get 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 18

Let's proceed to step 3:
The number 18 fits into 98 5 times, leaving a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 55.0
Subtract 90 from 98 to get 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 18

Let's proceed to step 4:
18 goes into 84 4 times with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 554.0
Subtracting 72 from 84 leaves us with 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 18

Moving on to step 5:
If we divide 121 by 18, we get 6 and a remainder of 13.
Use 6 as the next digit of our solution. 
Result so far: 5546.0
Subtracting 108 from 121 leaves us with 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 18

On to step 6:
If we divide 138 by 18, we get 7 and a remainder of 12.
The next digit of our result is 7. 
Result so far: 55467.0
Deduct 126 from 138 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
When dividing 120 by 18, we get 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 55467.6
Subtracting 108 from 120 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
When dividing 120 by 18, we get 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 55467.66
Subtracting 108 from 120 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 55467.66 and a remainder of 0.012.
