Let's divide 303545 by 75
We want to divide 303545 by 75.

Going ahead 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
The remainder is 3 after subtracting 0 from 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 75

On to step 2:
The number 75 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 75

Moving on to step 3:
If we divide 303 by 75, we get 4 and a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 300 away from 303, we end up with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 75

Going ahead to step 4:
The number 75 fits into 35 0 times, leaving a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 40.0
Subtract 0 from 35 to get 35.
Fetch the next digit (4) from the dividend, attach it to 35 and continue: 354 / 75

Step 5:
The number 75 fits into 354 4 times, leaving a remainder of 54.
The next digit of our result is 4. 
Result so far: 404.0
Subtract 300 from 354 to get 54.
Take the next digit (5) from the dividend and append it to 54, then repeat: 545 / 75

Moving on to step 6:
The number 75 fits into 545 7 times, leaving a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 4047.0
If we take 525 away from 545, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
The number 75 fits into 200 2 times, leaving a remainder of 50.
Put 2 as the next digit of the answer. 
Result so far: 4047.2
If we subtract 150 from 200, 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.

Advancing to step 8:
75 can be fit into 500 6 times, resulting in a remainder of 50.
The next digit of our result is 6. 
Result so far: 4047.26
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.

Step 9:
The number 75 fits into 500 6 times, leaving a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 4047.266
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 final result is 4047.266 with a remainder of 0.005.
