303670 ÷ 75 
Our goal is to divide 303670 by 75.

Advancing to step 1:
75 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 75

Moving on to step 2:
If we divide 30 by 75, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Append the next digit (3) from the dividend to 30 and continue with: 303 / 75

Going ahead to step 3:
The number 75 fits into 303 4 times, leaving a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 300 from 303 to get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 75

Going ahead to step 4:
75 goes into 36 0 times with a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
If we subtract 0 from 36, we get 36.
Take the next digit (7) from the dividend and append it to 36, then repeat: 367 / 75

Step 5:
75 goes into 367 4 times with a remainder of 67.
Put 4 as the next digit of the answer. 
Result so far: 404.0
Subtracting 300 from 367 leaves us with 67.
Include the next digit (0) from the dividend after 67, then repeat: 670 / 75

On to step 6:
670 divided by 75 is 8 with a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 4048.0
Deduct 600 from 670 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 7:
If we divide 700 by 75, we get 9 and a remainder of 25.
Use 9 as the next digit of our solution. 
Result so far: 4048.9
If we subtract 675 from 700, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 8:
If we divide 250 by 75, we get 3 and a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 4048.93
Deduct 225 from 250 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 9:
75 can be fit into 250 3 times, resulting in a remainder of 25.
The next digit of our result is 3. 
Result so far: 4048.933
If we take 225 away from 250, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 4048.933 with a remaining 0.0025.
