Let's divide 808287 by 2
We're looking to find how many times 2 goes into 808287.

Going ahead to step 1:
The number 2 fits into 8 4 times, leaving a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 8 from 8, we get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 2

Step 2:
2 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
Subtract 0 from 0 to get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 2

Moving on to step 3:
When dividing 8 by 2, we get 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 404.0
Deduct 8 from 8 and we're left with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 2

Step 4:
2 goes into 2 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 4041.0
Subtracting 2 from 2 leaves us with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 2

On to step 5:
When dividing 8 by 2, we get 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 40414.0
Subtract 8 from 8 to get 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 2

Let's proceed to step 6:
If we divide 7 by 2, we get 3 and a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 404143.0
If we take 6 away from 7, 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.

Moving on to step 7:
2 can be fit into 10 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 404143.5
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.

Let's proceed to step 8:
2 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 404143.5
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.

Moving on to step 9:
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: 404143.5
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.

After the division, we end up with 404143.5 and a remainder of 0.0.
