Let's divide 808436 by 2
We're looking to find how many times 2 goes into 808436.

On to step 1:
The number 2 fits into 8 4 times, leaving a remainder of 0.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 8 from 8 to get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 2

Going ahead to step 2:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 40.0
If we subtract 0 from 0, we get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 2

Let's proceed to step 3:
When dividing 8 by 2, we get 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 404.0
If we take 8 away from 8, we end up with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 2

Step 4:
The number 2 fits into 4 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 4042.0
If we subtract 4 from 4, we get 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 2

Moving on to step 5:
2 can be fit into 3 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 40421.0
Subtract 2 from 3 to get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 2

Let's proceed to step 6:
The number 2 fits into 16 8 times, leaving a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 404218.0
Deduct 16 from 16 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 7:
When dividing 0 by 2, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 404218.0
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.

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: 404218.0
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.

The quotient of the division is 404218.0, and the remainder is 0.0.
