We divide 279409 by 72
Let's see how many times 72 fits into 279409.

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
Subtracting 0 from 2 leaves us with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 72

Moving on to step 2:
27 divided by 72 is 0 with a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 27 and we're left with 27.
Grab the next digit (9) from the dividend, add it to 27, then carry on: 279 / 72

Advancing to step 3:
If we divide 279 by 72, we get 3 and a remainder of 63.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 216 from 279 to get 63.
Grab the next digit (4) from the dividend, add it to 63, then carry on: 634 / 72

Let's proceed to step 4:
72 can be fit into 634 8 times, resulting in a remainder of 58.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Subtracting 576 from 634 leaves us with 58.
Grab the next digit (0) from the dividend, add it to 58, then carry on: 580 / 72

On to step 5:
When dividing 580 by 72, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 388.0
Subtract 576 from 580 to get 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 72

Moving on to step 6:
72 can be fit into 49 0 times, resulting in a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 3880.0
Deduct 0 from 49 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 7:
When dividing 490 by 72, we get 6 with a remainder of 58.
The number 6 becomes the next digit in our result. 
Result so far: 3880.6
If we subtract 432 from 490, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 8:
If we divide 580 by 72, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 3880.68
The remainder is 4 after subtracting 576 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
When dividing 40 by 72, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 3880.68
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
When dividing 400 by 72, we get 5 with a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 3880.6805
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
400 divided by 72 is 5 with a remainder of 40.
The next digit of our result is 5. 
Result so far: 3880.68055
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 3880.68055 with a remainder of 4e-05.
