We're dividing 89820 by 18 
We want to figure out the number of times 89820 can be divided by 18.

On to step 1:
If we divide 8 by 18, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 18

Step 2:
The number 18 fits into 89 4 times, leaving a remainder of 17.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 17 after subtracting 72 from 89.
Include the next digit (8) from the dividend after 17, then repeat: 178 / 18

Let's proceed to step 3:
If we divide 178 by 18, we get 9 and a remainder of 16.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
Subtract 162 from 178 to get 16.
Take the next digit (2) from the dividend and append it to 16, then repeat: 162 / 18

On to step 4:
If we divide 162 by 18, we get 9 and a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 499.0
The remainder is 0 after subtracting 162 from 162.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 18

Going ahead to step 5:
18 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4990.0
If we take 0 away from 0, we end up 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.

Going ahead to step 6:
18 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4990.0
Subtract 0 from 0 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.

Advancing to step 7:
The number 18 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4990.0
Subtract 0 from 0 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.

The final outcome is 4990.0, with a leftover of 0.0.
