We look at the division of 449939 by 75 
We're looking to find how many times 75 goes into 449939.

Step 1:
4 divided by 75 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 75

Going ahead to step 2:
75 goes into 44 0 times with a remainder of 44.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 44 after subtracting 0 from 44.
Append the next digit (9) from the dividend to 44 and continue with: 449 / 75

Step 3:
If we divide 449 by 75, we get 5 and a remainder of 74.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 375 from 449 and we're left with 74.
Append the next digit (9) from the dividend to 74 and continue with: 749 / 75

On to step 4:
If we divide 749 by 75, we get 9 and a remainder of 74.
Use 9 as the next digit of our solution. 
Result so far: 59.0
If we subtract 675 from 749, we get 74.
Bring next digit (3) of the dividend behind the 74 and repeat the process: 743 / 75

Going ahead to step 5:
75 can be fit into 743 9 times, resulting in a remainder of 68.
Write down 9 as next digit of the result. 
Result so far: 599.0
If we take 675 away from 743, we end up with 68.
Fetch the next digit (9) from the dividend, attach it to 68 and continue: 689 / 75

Moving on to step 6:
689 divided by 75 is 9 with a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 5999.0
Subtract 675 from 689 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
75 goes into 140 1 times with a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 5999.1
If we subtract 75 from 140, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 8:
When dividing 650 by 75, we get 8 with a remainder of 50.
Use 8 as the next digit of our solution. 
Result so far: 5999.18
If we subtract 600 from 650, 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.

Going ahead to step 9:
The number 75 fits into 500 6 times, leaving a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 5999.186
If we take 450 away from 500, 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 10:
When dividing 500 by 75, we get 6 with a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 5999.1866
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.

Our division results in 5999.1866 with a remaining 0.0005.
