Let's divide 988438 by 18
We're looking to find how many times 18 goes into 988438.

Moving on to step 1:
The number 18 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 18

On to step 2:
18 can be fit into 98 5 times, resulting in a remainder of 8.
The next digit of our result is 5. 
Result so far: 5.0
If we take 90 away from 98, we end up with 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 18

Moving on to step 3:
The number 18 fits into 88 4 times, leaving a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 54.0
If we subtract 72 from 88, we get 16.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 18

Moving on to step 4:
164 divided by 18 is 9 with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 549.0
The remainder is 2 after subtracting 162 from 164.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 18

Advancing to step 5:
18 can be fit into 23 1 times, resulting in a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 5491.0
Subtracting 18 from 23 leaves us with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 18

Let's proceed to step 6:
The number 18 fits into 58 3 times, leaving a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 54913.0
Subtract 54 from 58 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
If we divide 40 by 18, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 54913.2
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
The number 18 fits into 40 2 times, leaving a remainder of 4.
The next digit of our result is 2. 
Result so far: 54913.22
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 54913.22, and the remainder is 0.004.
