We look at the division of 72063999 by 239 
Let's see how many times 239 fits into 72063999.

Advancing to step 1:
239 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 239

On to step 2:
When dividing 72 by 239, we get 0 with a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Append the next digit (0) from the dividend to 72 and continue with: 720 / 239

On to step 3:
239 goes into 720 3 times with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 717 from 720 and we're left with 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 239

Let's proceed to step 4:
239 can be fit into 36 0 times, resulting in a remainder of 36.
Write down 0 as next digit of the result. 
Result so far: 30.0
The remainder is 36 after subtracting 0 from 36.
Take the next digit (3) from the dividend and append it to 36, then repeat: 363 / 239

Advancing to step 5:
If we divide 363 by 239, we get 1 and a remainder of 124.
Use 1 as the next digit of our solution. 
Result so far: 301.0
Subtracting 239 from 363 leaves us with 124.
Include the next digit (9) from the dividend after 124, then repeat: 1249 / 239

Advancing to step 6:
The number 239 fits into 1249 5 times, leaving a remainder of 54.
The next digit of our result is 5. 
Result so far: 3015.0
If we take 1195 away from 1249, we end up with 54.
Take the next digit (9) from the dividend and append it to 54, then repeat: 549 / 239

On to step 7:
549 divided by 239 is 2 with a remainder of 71.
Put 2 as the next digit of the answer. 
Result so far: 30152.0
If we subtract 478 from 549, we get 71.
Include the next digit (9) from the dividend after 71, then repeat: 719 / 239

On to step 8:
If we divide 719 by 239, we get 3 and a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 301523.0
Subtract 717 from 719 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
If we divide 20 by 239, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 301523.0
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
239 goes into 200 0 times with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 301523.0
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Our division results in 301523.0 with a remaining 0.2.
