310388 divided by 75 
We're looking to find how many times 75 goes into 310388.

Moving on to step 1:
75 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 75

Advancing to step 2:
31 divided by 75 is 0 with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Fetch the next digit (0) from the dividend, attach it to 31 and continue: 310 / 75

Step 3:
If we divide 310 by 75, we get 4 and a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 300 from 310, we get 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 75

On to step 4:
The number 75 fits into 103 1 times, leaving a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
The remainder is 28 after subtracting 75 from 103.
Include the next digit (8) from the dividend after 28, then repeat: 288 / 75

Moving on to step 5:
75 can be fit into 288 3 times, resulting in a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 413.0
Subtracting 225 from 288 leaves us with 63.
Take the next digit (8) from the dividend and append it to 63, then repeat: 638 / 75

Moving on to step 6:
When dividing 638 by 75, we get 8 with a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 4138.0
If we take 600 away from 638, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 7:
380 divided by 75 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 4138.5
Subtract 375 from 380 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
75 goes into 50 0 times with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 4138.5
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 9:
If we divide 500 by 75, we get 6 and a remainder of 50.
The next digit of our result is 6. 
Result so far: 4138.506
The remainder is 50 after subtracting 450 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
75 goes into 500 6 times with a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 4138.5066
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 4138.5066, and the remainder is 0.0005.
