We look at the division of 343255 by 75 
We want to divide 343255 by 75.

Let's proceed to step 1:
The number 75 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 75

Going ahead to step 2:
75 can be fit into 34 0 times, resulting in a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Bring next digit (3) of the dividend behind the 34 and repeat the process: 343 / 75

On to step 3:
The number 75 fits into 343 4 times, leaving a remainder of 43.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 300 away from 343, we end up with 43.
Include the next digit (2) from the dividend after 43, then repeat: 432 / 75

Let's proceed to step 4:
75 goes into 432 5 times with a remainder of 57.
Use 5 as the next digit of our solution. 
Result so far: 45.0
If we subtract 375 from 432, we get 57.
Append the next digit (5) from the dividend to 57 and continue with: 575 / 75

Step 5:
75 goes into 575 7 times with a remainder of 50.
The number 7 becomes the next digit in our result. 
Result so far: 457.0
The remainder is 50 after subtracting 525 from 575.
Grab the next digit (5) from the dividend, add it to 50, then carry on: 505 / 75

Moving on to step 6:
75 goes into 505 6 times with a remainder of 55.
Put 6 as the next digit of the answer. 
Result so far: 4576.0
The remainder is 55 after subtracting 450 from 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 7:
75 goes into 550 7 times with a remainder of 25.
Use 7 as the next digit of our solution. 
Result so far: 4576.7
Subtracting 525 from 550 leaves us 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.

On to step 8:
75 can be fit into 250 3 times, resulting in a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 4576.73
The remainder is 25 after subtracting 225 from 250.
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 9:
The number 75 fits into 250 3 times, leaving a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 4576.733
The remainder is 25 after subtracting 225 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The quotient of the division is 4576.733, and the remainder is 0.0025.
