We look at the division of 21484 by 18 
Let's see how many times 18 fits into 21484.

Moving on to step 1:
The number 18 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 18

Going ahead to step 2:
If we divide 21 by 18, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 18 from 21 to get 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 18

Step 3:
34 divided by 18 is 1 with a remainder of 16.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 18 from 34, we get 16.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 18

On to step 4:
When dividing 168 by 18, we get 9 with a remainder of 6.
The next digit of our result is 9. 
Result so far: 119.0
Deduct 162 from 168 and we're left with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 18

Step 5:
The number 18 fits into 64 3 times, leaving a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 1193.0
Deduct 54 from 64 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 6:
100 divided by 18 is 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 1193.5
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
18 can be fit into 100 5 times, resulting in a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 1193.55
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 1193.55 and a remainder of 0.01.
