We're dividing 349390 by 75 
Our goal is to divide 349390 by 75.

Let's proceed to step 1:
If we divide 3 by 75, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 75

Going ahead to step 2:
The number 75 fits into 34 0 times, leaving a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Fetch the next digit (9) from the dividend, attach it to 34 and continue: 349 / 75

Going ahead to step 3:
The number 75 fits into 349 4 times, leaving a remainder of 49.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 49 after subtracting 300 from 349.
Fetch the next digit (3) from the dividend, attach it to 49 and continue: 493 / 75

Step 4:
The number 75 fits into 493 6 times, leaving a remainder of 43.
Put 6 as the next digit of the answer. 
Result so far: 46.0
If we subtract 450 from 493, we get 43.
Take the next digit (9) from the dividend and append it to 43, then repeat: 439 / 75

On to step 5:
75 can be fit into 439 5 times, resulting in a remainder of 64.
Write down 5 as next digit of the result. 
Result so far: 465.0
Subtracting 375 from 439 leaves us with 64.
Include the next digit (0) from the dividend after 64, then repeat: 640 / 75

Step 6:
If we divide 640 by 75, we get 8 and a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 4658.0
Subtracting 600 from 640 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 7:
75 goes into 400 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 4658.5
If we subtract 375 from 400, 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.

Advancing to step 8:
250 divided by 75 is 3 with a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 4658.53
Subtract 225 from 250 to 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.

Advancing to step 9:
If we divide 250 by 75, we get 3 and a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 4658.533
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.

In conclusion, the division gives 4658.533 with a balance of 0.0025.
