We look at the division of 310938 by 72 
We want to figure out the number of times 310938 can be divided by 72.

On to step 1:
When dividing 3 by 72, we get 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.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 72

Moving on to step 2:
When dividing 31 by 72, we get 0 with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 72

On to step 3:
If we divide 310 by 72, we get 4 and a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 288 from 310 and we're left with 22.
Fetch the next digit (9) from the dividend, attach it to 22 and continue: 229 / 72

Advancing to step 4:
72 goes into 229 3 times with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 43.0
If we take 216 away from 229, we end up with 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 72

On to step 5:
If we divide 133 by 72, we get 1 and a remainder of 61.
Put 1 as the next digit of the answer. 
Result so far: 431.0
Deduct 72 from 133 and we're left with 61.
Append the next digit (8) from the dividend to 61 and continue with: 618 / 72

On to step 6:
If we divide 618 by 72, we get 8 and a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 4318.0
Subtracting 576 from 618 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 7:
420 divided by 72 is 5 with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 4318.5
If we subtract 360 from 420, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 8:
When dividing 600 by 72, we get 8 with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 4318.58
If we take 576 away from 600, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 9:
If we divide 240 by 72, we get 3 and a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 4318.583
Deduct 216 from 240 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
The number 72 fits into 240 3 times, leaving a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 4318.5833
Subtracting 216 from 240 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 4318.5833, and the remainder is 0.00024.
