We're dividing 310252 by 72 
We want to figure out the number of times 310252 can be divided by 72.

Moving on to step 1:
72 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 72

On to step 2:
72 can be fit into 31 0 times, resulting in 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.
Append the next digit (0) from the dividend to 31 and continue with: 310 / 72

Going ahead to step 3:
72 can be fit into 310 4 times, resulting in a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 288 from 310 and we're left with 22.
Include the next digit (2) from the dividend after 22, then repeat: 222 / 72

Step 4:
If we divide 222 by 72, we get 3 and a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 43.0
Deduct 216 from 222 and we're left with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 72

Moving on to step 5:
If we divide 65 by 72, we get 0 and a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 430.0
Subtracting 0 from 65 leaves us with 65.
Bring next digit (2) of the dividend behind the 65 and repeat the process: 652 / 72

Going ahead to step 6:
652 divided by 72 is 9 with a remainder of 4.
The next digit of our result is 9. 
Result so far: 4309.0
Subtracting 648 from 652 leaves us 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.

On to step 7:
If we divide 40 by 72, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 4309.0
Subtracting 0 from 40 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.

Moving on to step 8:
72 can be fit into 400 5 times, resulting in a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 4309.05
If we subtract 360 from 400, we 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.

Going ahead to step 9:
400 divided by 72 is 5 with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 4309.055
If we subtract 360 from 400, we 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.

Our division results in 4309.055 with a remaining 0.004.
