989890 ÷ 18 
We want to divide 989890 by 18.

Advancing to step 1:
18 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 18

Moving on to step 2:
18 goes into 98 5 times with a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 90 from 98 and we're left with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 18

Going ahead to step 3:
18 can be fit into 89 4 times, resulting in a remainder of 17.
The number 4 becomes the next digit in our result. 
Result so far: 54.0
Subtract 72 from 89 to get 17.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 18

Step 4:
178 divided by 18 is 9 with a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 549.0
Subtracting 162 from 178 leaves us with 16.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 18

On to step 5:
When dividing 169 by 18, we get 9 with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 5499.0
Subtracting 162 from 169 leaves us with 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 18

Advancing to step 6:
The number 18 fits into 70 3 times, leaving a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 54993.0
Subtract 54 from 70 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
18 can be fit into 160 8 times, resulting in a remainder of 16.
The next digit of our result is 8. 
Result so far: 54993.8
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
18 can be fit into 160 8 times, resulting in a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 54993.88
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 54993.88, and the remainder is 0.016.
