We look at the division of 33820 by 72 
We want to divide 33820 by 72.

Advancing to step 1:
The number 72 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 72

Advancing to step 2:
72 can be fit into 33 0 times, resulting in a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 33, we get 33.
Bring next digit (8) of the dividend behind the 33 and repeat the process: 338 / 72

On to step 3:
The number 72 fits into 338 4 times, leaving a remainder of 50.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 288 from 338 to get 50.
Include the next digit (2) from the dividend after 50, then repeat: 502 / 72

Advancing to step 4:
When dividing 502 by 72, we get 6 with a remainder of 70.
Write down 6 as next digit of the result. 
Result so far: 46.0
If we take 432 away from 502, we end up with 70.
Include the next digit (0) from the dividend after 70, then repeat: 700 / 72

Let's proceed to step 5:
When dividing 700 by 72, we get 9 with a remainder of 52.
The number 9 becomes the next digit in our result. 
Result so far: 469.0
Deduct 648 from 700 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 6:
If we divide 520 by 72, we get 7 and a remainder of 16.
The next digit of our result is 7. 
Result so far: 469.7
Subtracting 504 from 520 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
72 can be fit into 160 2 times, resulting in a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 469.72
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 8:
The number 72 fits into 160 2 times, leaving a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 469.722
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 469.722 with a remaining 0.0016.
