We look at the division of 429449 by 75 
Let's see how many times 75 fits into 429449.

Going ahead to step 1:
4 divided by 75 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 75

Going ahead to step 2:
75 goes into 42 0 times with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Bring next digit (9) of the dividend behind the 42 and repeat the process: 429 / 75

Going ahead to step 3:
75 can be fit into 429 5 times, resulting in a remainder of 54.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 375 from 429, we get 54.
Include the next digit (4) from the dividend after 54, then repeat: 544 / 75

Step 4:
75 can be fit into 544 7 times, resulting in a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 57.0
If we take 525 away from 544, we end up with 19.
Take the next digit (4) from the dividend and append it to 19, then repeat: 194 / 75

Going ahead to step 5:
The number 75 fits into 194 2 times, leaving a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 572.0
Subtracting 150 from 194 leaves us with 44.
Include the next digit (9) from the dividend after 44, then repeat: 449 / 75

Moving on to step 6:
449 divided by 75 is 5 with a remainder of 74.
The number 5 becomes the next digit in our result. 
Result so far: 5725.0
The remainder is 74 after subtracting 375 from 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 7:
When dividing 740 by 75, we get 9 with a remainder of 65.
The next digit of our result is 9. 
Result so far: 5725.9
Subtracting 675 from 740 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 8:
When dividing 650 by 75, we get 8 with a remainder of 50.
Record the quotient 8 as the next digit in the result. 
Result so far: 5725.98
If we take 600 away from 650, we end up 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.

Moving on to step 9:
If we divide 500 by 75, we get 6 and a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 5725.986
The remainder is 50 after subtracting 450 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
When dividing 500 by 75, we get 6 with a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 5725.9866
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.

The quotient of the division is 5725.9866, and the remainder is 0.0005.
