Let's divide 313939 by 72
Our goal is to divide 313939 by 72.

On to step 1:
3 divided by 72 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 72

Let's proceed to step 2:
The number 72 fits into 31 0 times, leaving a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Include the next digit (3) from the dividend after 31, then repeat: 313 / 72

Step 3:
If we divide 313 by 72, we get 4 and a remainder of 25.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 288 from 313 to get 25.
Grab the next digit (9) from the dividend, add it to 25, then carry on: 259 / 72

Moving on to step 4:
259 divided by 72 is 3 with a remainder of 43.
Write down 3 as next digit of the result. 
Result so far: 43.0
Deduct 216 from 259 and we're left with 43.
Take the next digit (3) from the dividend and append it to 43, then repeat: 433 / 72

Going ahead to step 5:
The number 72 fits into 433 6 times, leaving a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 436.0
Subtract 432 from 433 to get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 72

Advancing to step 6:
72 goes into 19 0 times with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 4360.0
If we take 0 away from 19, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
If we divide 190 by 72, we get 2 and a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 4360.2
Subtracting 144 from 190 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 8:
When dividing 460 by 72, we get 6 with a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 4360.26
Subtract 432 from 460 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 9:
72 goes into 280 3 times with a remainder of 64.
Use 3 as the next digit of our solution. 
Result so far: 4360.263
The remainder is 64 after subtracting 216 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 10:
If we divide 640 by 72, we get 8 and a remainder of 64.
The next digit of our result is 8. 
Result so far: 4360.2638
The remainder is 64 after subtracting 576 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 11:
When dividing 640 by 72, we get 8 with a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 4360.26388
If we subtract 576 from 640, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 4360.26388 with a remainder of 6.4e-05.
