We're dividing 72084 by 4 
Let's see how many times 4 fits into 72084.

Step 1:
4 can be fit into 7 1 times, resulting in a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 4 from 7 and we're left with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 4

Moving on to step 2:
4 goes into 32 8 times with a remainder of 0.
The next digit of our result is 8. 
Result so far: 18.0
Deduct 32 from 32 and we're left with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 4

Advancing to step 3:
4 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 180.0
Deduct 0 from 0 and we're left with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 4

On to step 4:
4 goes into 8 2 times with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 1802.0
Subtract 8 from 8 to get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 4

On to step 5:
4 divided by 4 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 18021.0
Subtract 4 from 4 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 6:
When dividing 0 by 4, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 18021.0
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 7:
4 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 18021.0
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.

After the division, we end up with 18021.0 and a remainder of 0.0.
