360900 ÷ 20 
Our goal is to divide 360900 by 20.

On to step 1:
3 divided by 20 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 20

Advancing to step 2:
If we divide 36 by 20, we get 1 and a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 20 away from 36, we end up with 16.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 20

Moving on to step 3:
When dividing 160 by 20, we get 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtract 160 from 160 to get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 20

On to step 4:
When dividing 9 by 20, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 180.0
Subtract 0 from 9 to get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 20

Step 5:
20 goes into 90 4 times with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 1804.0
If we subtract 80 from 90, we get 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 20

Let's proceed to step 6:
If we divide 100 by 20, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 18045.0
The remainder is 0 after subtracting 100 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 18045.0
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.

Step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 18045.0
Deduct 0 from 0 and we're left 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.

The quotient of the division is 18045.0, and the remainder is 0.0.
