816613 divided by 2 
Let's see how many times 2 fits into 816613.

On 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.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 2

Moving on to step 2:
1 divided by 2 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 40.0
Subtract 0 from 1 to get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 2

Going ahead to step 3:
2 goes into 16 8 times with a remainder of 0.
The next digit of our result is 8. 
Result so far: 408.0
Deduct 16 from 16 and we're left with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 2

Step 4:
2 goes into 6 3 times with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 4083.0
If we subtract 6 from 6, we get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 2

Going ahead to step 5:
2 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 40830.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 2

Going ahead to step 6:
13 divided by 2 is 6 with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 408306.0
Subtract 12 from 13 to get 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:
10 divided by 2 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 408306.5
The remainder is 0 after subtracting 10 from 10.
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:
If we divide 0 by 2, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 408306.5
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.

Step 9:
0 divided by 2 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 408306.5
If we subtract 0 from 0, 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.

After the division, we end up with 408306.5 and a remainder of 0.0.
