805009 divided by 2 
Our goal is to divide 805009 by 2.

Let's proceed to step 1:
2 can be fit into 8 4 times, resulting in a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 8 away from 8, we end up with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 2

Advancing to step 2:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
If we take 0 away from 0, we end up with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 2

Going ahead to step 3:
2 can be fit into 5 2 times, resulting in a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 402.0
If we subtract 4 from 5, we get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 2

Moving on to step 4:
The number 2 fits into 10 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 4025.0
Deduct 10 from 10 and we're left with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 2

Moving on to step 5:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 40250.0
If we take 0 away from 0, we end up with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 2

Step 6:
When dividing 9 by 2, we get 4 with a remainder of 1.
The next digit of our result is 4. 
Result so far: 402504.0
Subtracting 8 from 9 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
2 goes into 10 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 402504.5
If we subtract 10 from 10, 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.

Step 8:
0 divided by 2 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 402504.5
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.

Advancing 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: 402504.5
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 result is 402504.5 with a remainder of 0.0.
