We're dividing 310383 by 75 
Our goal is to divide 310383 by 75.

On to step 1:
When dividing 3 by 75, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 75

Going ahead to step 2:
31 divided by 75 is 0 with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 75

Going ahead to step 3:
75 goes into 310 4 times with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 300 away from 310, we end up with 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 75

On to step 4:
75 can be fit into 103 1 times, resulting in a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
If we take 75 away from 103, we end up with 28.
Fetch the next digit (8) from the dividend, attach it to 28 and continue: 288 / 75

Going ahead to step 5:
The number 75 fits into 288 3 times, leaving a remainder of 63.
The next digit of our result is 3. 
Result so far: 413.0
If we subtract 225 from 288, we get 63.
Bring next digit (3) of the dividend behind the 63 and repeat the process: 633 / 75

Step 6:
75 can be fit into 633 8 times, resulting in a remainder of 33.
Write down 8 as next digit of the result. 
Result so far: 4138.0
The remainder is 33 after subtracting 600 from 633.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 7:
The number 75 fits into 330 4 times, leaving a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 4138.4
Subtract 300 from 330 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
75 can be fit into 300 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 4138.44
Deduct 300 from 300 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 4138.44, with a leftover of 0.0.
