We divide 66239 by 72
We're looking to find how many times 72 goes into 66239.

On to step 1:
6 divided by 72 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 72

On to step 2:
If we divide 66 by 72, we get 0 and a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Append the next digit (2) from the dividend to 66 and continue with: 662 / 72

Going ahead to step 3:
662 divided by 72 is 9 with a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 648 from 662 leaves us with 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 72

Let's proceed to step 4:
When dividing 143 by 72, we get 1 with a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
Subtracting 72 from 143 leaves us with 71.
Include the next digit (9) from the dividend after 71, then repeat: 719 / 72

Let's proceed to step 5:
When dividing 719 by 72, we get 9 with a remainder of 71.
Write down 9 as next digit of the result. 
Result so far: 919.0
Subtract 648 from 719 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 6:
710 divided by 72 is 9 with a remainder of 62.
Write down 9 as next digit of the result. 
Result so far: 919.9
Subtract 648 from 710 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 7:
620 divided by 72 is 8 with a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 919.98
Subtract 576 from 620 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 8:
The number 72 fits into 440 6 times, leaving a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 919.986
Subtracting 432 from 440 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
80 divided by 72 is 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 919.9861
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
When dividing 80 by 72, we get 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 919.98611
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 919.98611, with a leftover of 8e-06.
