We look at the division of 285449 by 75 
We're looking to find how many times 75 goes into 285449.

Going ahead to step 1:
When dividing 2 by 75, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 75

Let's proceed to step 2:
When dividing 28 by 75, we get 0 with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Bring next digit (5) of the dividend behind the 28 and repeat the process: 285 / 75

Moving on to step 3:
75 can be fit into 285 3 times, resulting in a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 225 from 285 to get 60.
Include the next digit (4) from the dividend after 60, then repeat: 604 / 75

Step 4:
604 divided by 75 is 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 38.0
Deduct 600 from 604 and we're left with 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 75

On to step 5:
If we divide 44 by 75, we get 0 and a remainder of 44.
Use 0 as the next digit of our solution. 
Result so far: 380.0
Subtract 0 from 44 to get 44.
Grab the next digit (9) from the dividend, add it to 44, then carry on: 449 / 75

Step 6:
If we divide 449 by 75, we get 5 and a remainder of 74.
The number 5 becomes the next digit in our result. 
Result so far: 3805.0
Subtracting 375 from 449 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 7:
If we divide 740 by 75, we get 9 and a remainder of 65.
The number 9 becomes the next digit in our result. 
Result so far: 3805.9
Deduct 675 from 740 and we're left 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.

Moving on to step 8:
75 can be fit into 650 8 times, resulting in a remainder of 50.
The number 8 becomes the next digit in our result. 
Result so far: 3805.98
Subtracting 600 from 650 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.

Let's proceed to step 9:
500 divided by 75 is 6 with a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 3805.986
Deduct 450 from 500 and we're left 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.

Going ahead to step 10:
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: 3805.9866
If we subtract 450 from 500, 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.

The final result is 3805.9866 with a remainder of 0.0005.
