We look at the division of 449875 by 1 
We're looking to find how many times 1 goes into 449875.

On to step 1:
1 can be fit into 4 4 times, resulting in a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 4 from 4 leaves us with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 1

Going ahead to step 2:
1 can be fit into 4 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 44.0
Subtracting 4 from 4 leaves us with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 1

Advancing to step 3:
If we divide 9 by 1, we get 9 and a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 449.0
If we take 9 away from 9, we end up with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 1

On to step 4:
When dividing 8 by 1, we get 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 4498.0
Subtract 8 from 8 to get 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 1

Moving on to step 5:
If we divide 7 by 1, we get 7 and a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 44987.0
Deduct 7 from 7 and we're left with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 1

Advancing to step 6:
The number 1 fits into 5 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 449875.0
Deduct 5 from 5 and we're left 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.

Step 7:
1 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 449875.0
If we take 0 away from 0, we end up 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.

On to step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 449875.0
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.

In conclusion, the division gives 449875.0 with a balance of 0.0.
