303938 ÷ 75 
Our goal is to divide 303938 by 75.

Advancing to step 1:
75 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 75

Let's proceed to step 2:
If we divide 30 by 75, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 75

Moving on to step 3:
75 goes into 303 4 times with a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 3 after subtracting 300 from 303.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 75

Moving on to step 4:
If we divide 39 by 75, we get 0 and a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 40.0
The remainder is 39 after subtracting 0 from 39.
Take the next digit (3) from the dividend and append it to 39, then repeat: 393 / 75

Step 5:
393 divided by 75 is 5 with a remainder of 18.
Use 5 as the next digit of our solution. 
Result so far: 405.0
If we subtract 375 from 393, we get 18.
Append the next digit (8) from the dividend to 18 and continue with: 188 / 75

On to step 6:
75 goes into 188 2 times with a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 4052.0
If we subtract 150 from 188, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 7:
The number 75 fits into 380 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 4052.5
If we take 375 away from 380, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
75 goes into 50 0 times with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 4052.5
Deduct 0 from 50 and we're left with 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.
Use 6 as the next digit of our solution. 
Result so far: 4052.506
If we take 450 away from 500, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
75 can be fit into 500 6 times, resulting in a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 4052.5066
Subtracting 450 from 500 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 4052.5066 and a remainder of 0.0005.
