909903 divided by 2 
Our goal is to divide 909903 by 2.

Moving on to step 1:
2 can be fit into 9 4 times, resulting in a remainder of 1.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 8 from 9 and we're left with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 2

On to step 2:
If we divide 10 by 2, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 45.0
If we take 10 away from 10, we end up with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 2

Advancing to step 3:
The number 2 fits into 9 4 times, leaving a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 454.0
If we take 8 away from 9, we end up with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 2

Moving on to step 4:
When dividing 19 by 2, we get 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 4549.0
If we subtract 18 from 19, we get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 2

Let's proceed to step 5:
10 divided by 2 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 45495.0
Deduct 10 from 10 and we're left with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 2

On to step 6:
2 can be fit into 3 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 454951.0
If we subtract 2 from 3, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
10 divided by 2 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 454951.5
The remainder is 0 after subtracting 10 from 10.
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 8:
2 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: 454951.5
Deduct 0 from 0 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 9:
0 divided by 2 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 454951.5
Subtracting 0 from 0 leaves us 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.

The final outcome is 454951.5, with a leftover of 0.0.
