We divide 393106 by 72
Let's see how many times 72 fits into 393106.

On to step 1:
3 divided by 72 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 72

On to step 2:
The number 72 fits into 39 0 times, leaving a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Grab the next digit (3) from the dividend, add it to 39, then carry on: 393 / 72

Moving on to step 3:
393 divided by 72 is 5 with a remainder of 33.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 360 from 393 leaves us with 33.
Fetch the next digit (1) from the dividend, attach it to 33 and continue: 331 / 72

Let's proceed to step 4:
The number 72 fits into 331 4 times, leaving a remainder of 43.
The number 4 becomes the next digit in our result. 
Result so far: 54.0
If we subtract 288 from 331, we get 43.
Grab the next digit (0) from the dividend, add it to 43, then carry on: 430 / 72

On to step 5:
72 can be fit into 430 5 times, resulting in a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 545.0
Subtract 360 from 430 to get 70.
Include the next digit (6) from the dividend after 70, then repeat: 706 / 72

Advancing to step 6:
72 goes into 706 9 times with a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 5459.0
Deduct 648 from 706 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 7:
If we divide 580 by 72, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 5459.8
Deduct 576 from 580 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
72 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 5459.8
Deduct 0 from 40 and we're left 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.

Moving on to step 9:
72 goes into 400 5 times with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 5459.805
The remainder is 40 after subtracting 360 from 400.
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:
72 goes into 400 5 times with a remainder of 40.
The next digit of our result is 5. 
Result so far: 5459.8055
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.

The final result is 5459.8055 with a remainder of 0.0004.
