909389 ÷ 2 
We're looking to find how many times 2 goes into 909389.

Moving on to step 1:
9 divided by 2 is 4 with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 8 from 9 to get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 2

Advancing to step 2:
10 divided by 2 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
Subtracting 10 from 10 leaves us with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 2

Let's proceed to step 3:
9 divided by 2 is 4 with a remainder of 1.
The next digit of our result is 4. 
Result so far: 454.0
If we subtract 8 from 9, we get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 2

On to step 4:
2 goes into 13 6 times with a remainder of 1.
The next digit of our result is 6. 
Result so far: 4546.0
Subtract 12 from 13 to get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 2

Moving on to step 5:
If we divide 18 by 2, we get 9 and a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 45469.0
Subtracting 18 from 18 leaves us with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 2

Moving on to step 6:
If we divide 9 by 2, we get 4 and a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 454694.0
The remainder is 1 after subtracting 8 from 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
The number 2 fits into 10 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 454694.5
If we take 10 away from 10, 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.

Let's proceed to step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 454694.5
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.

On to step 9:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 454694.5
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.

The final outcome is 454694.5, with a leftover of 0.0.
