We're dividing 279309 by 72 
We want to divide 279309 by 72.

Going ahead to step 1:
When dividing 2 by 72, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 72

Step 2:
The number 72 fits into 27 0 times, leaving a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 27, we end up with 27.
Bring next digit (9) of the dividend behind the 27 and repeat the process: 279 / 72

On to step 3:
72 can be fit into 279 3 times, resulting in a remainder of 63.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 216 from 279 leaves us with 63.
Include the next digit (3) from the dividend after 63, then repeat: 633 / 72

Moving on to step 4:
72 can be fit into 633 8 times, resulting in a remainder of 57.
The next digit of our result is 8. 
Result so far: 38.0
If we take 576 away from 633, we end up with 57.
Bring next digit (0) of the dividend behind the 57 and repeat the process: 570 / 72

On to step 5:
If we divide 570 by 72, we get 7 and a remainder of 66.
The next digit of our result is 7. 
Result so far: 387.0
The remainder is 66 after subtracting 504 from 570.
Include the next digit (9) from the dividend after 66, then repeat: 669 / 72

On to step 6:
When dividing 669 by 72, we get 9 with a remainder of 21.
The next digit of our result is 9. 
Result so far: 3879.0
If we take 648 away from 669, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
72 goes into 210 2 times with a remainder of 66.
Record the quotient 2 as the next digit in the result. 
Result so far: 3879.2
If we take 144 away from 210, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 8:
72 goes into 660 9 times with a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 3879.29
Subtract 648 from 660 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
When dividing 120 by 72, we get 1 with a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 3879.291
The remainder is 48 after subtracting 72 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 10:
When dividing 480 by 72, we get 6 with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 3879.2916
If we take 432 away from 480, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 11:
The number 72 fits into 480 6 times, leaving a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 3879.29166
If we subtract 432 from 480, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Our division results in 3879.29166 with a remaining 4.8e-05.
