We're dividing 346425 by 75 
We want to figure out the number of times 346425 can be divided by 75.

Step 1:
75 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 75

Step 2:
34 divided by 75 is 0 with a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Fetch the next digit (6) from the dividend, attach it to 34 and continue: 346 / 75

Let's proceed to step 3:
75 goes into 346 4 times with a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 300 from 346, we get 46.
Grab the next digit (4) from the dividend, add it to 46, then carry on: 464 / 75

Let's proceed to step 4:
The number 75 fits into 464 6 times, leaving a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
Deduct 450 from 464 and we're left with 14.
Bring next digit (2) of the dividend behind the 14 and repeat the process: 142 / 75

Step 5:
If we divide 142 by 75, we get 1 and a remainder of 67.
Record the quotient 1 as the next digit in the result. 
Result so far: 461.0
If we take 75 away from 142, we end up with 67.
Include the next digit (5) from the dividend after 67, then repeat: 675 / 75

Going ahead to step 6:
If we divide 675 by 75, we get 9 and a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 4619.0
If we subtract 675 from 675, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
The number 75 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4619.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
The number 75 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 4619.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 4619.0, and the remainder is 0.0.
