We look at the division of 800305 by 2 
We want to divide 800305 by 2.

On to step 1:
When dividing 8 by 2, we get 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 0 after subtracting 8 from 8.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 2

Going ahead to step 2:
0 divided by 2 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 40.0
Deduct 0 from 0 and we're left with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 2

Advancing to step 3:
When dividing 0 by 2, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 400.0
Subtracting 0 from 0 leaves us with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 2

On to step 4:
If we divide 3 by 2, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 4001.0
If we subtract 2 from 3, we get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 2

Let's proceed to step 5:
If we divide 10 by 2, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 40015.0
Subtracting 10 from 10 leaves us with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 2

Step 6:
The number 2 fits into 5 2 times, leaving a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 400152.0
If we take 4 away from 5, we end up 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.

On to step 7:
If we divide 10 by 2, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 400152.5
Deduct 10 from 10 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 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 400152.5
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.

Advancing to step 9:
0 divided by 2 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 400152.5
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 400152.5 with a remainder of 0.0.
