We divide 989631 by 18
Let's see how many times 18 fits into 989631.

Going ahead to step 1:
18 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 18

Moving on to step 2:
98 divided by 18 is 5 with a remainder of 8.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 90 from 98, we get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 18

Advancing to step 3:
18 can be fit into 89 4 times, resulting in a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 54.0
Subtracting 72 from 89 leaves us with 17.
Take the next digit (6) from the dividend and append it to 17, then repeat: 176 / 18

Let's proceed to step 4:
176 divided by 18 is 9 with a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 549.0
If we subtract 162 from 176, we get 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 18

Let's proceed to step 5:
18 can be fit into 143 7 times, resulting in a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 5497.0
If we subtract 126 from 143, we get 17.
Fetch the next digit (1) from the dividend, attach it to 17 and continue: 171 / 18

Step 6:
When dividing 171 by 18, we get 9 with a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 54979.0
Deduct 162 from 171 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
18 can be fit into 90 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 54979.5
Subtract 90 from 90 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
When dividing 0 by 18, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 54979.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
18 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 54979.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 54979.5 and a remainder of 0.0.
