490045 ÷ 1 
Let's see how many times 1 fits into 490045.

Moving on to step 1:
The number 1 fits into 4 4 times, leaving a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 4 from 4, we get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 1

Moving on to step 2:
When dividing 9 by 1, we get 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 49.0
The remainder is 0 after subtracting 9 from 9.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

Going ahead to step 3:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 490.0
If we subtract 0 from 0, we get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

Going ahead to step 4:
0 divided by 1 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4900.0
Subtracting 0 from 0 leaves us with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 1

Going ahead to step 5:
1 goes into 4 4 times with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 49004.0
Subtracting 4 from 4 leaves us with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 1

Moving on to step 6:
The number 1 fits into 5 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 490045.0
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.

Advancing to step 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 490045.0
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.

On to step 8:
When dividing 0 by 1, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 490045.0
If we subtract 0 from 0, 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.

After the division, we end up with 490045.0 and a remainder of 0.0.
