Let's divide 836511 by 2
We're looking to find how many times 2 goes into 836511.

Moving on to step 1:
2 goes into 8 4 times with a remainder of 0.
The next digit of our result is 4. 
Result so far: 4.0
If we take 8 away from 8, we end up with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 2

Going ahead to step 2:
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: 41.0
If we take 2 away from 3, we end up with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 2

Step 3:
The number 2 fits into 16 8 times, leaving a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 418.0
Subtracting 16 from 16 leaves us with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 2

Step 4:
The number 2 fits into 5 2 times, leaving a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 4182.0
Subtract 4 from 5 to get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 2

Step 5:
If we divide 11 by 2, we get 5 and a remainder of 1.
The next digit of our result is 5. 
Result so far: 41825.0
Deduct 10 from 11 and we're left with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 2

Step 6:
If we divide 11 by 2, we get 5 and a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 418255.0
If we take 10 away from 11, 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.

Step 7:
10 divided by 2 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 418255.5
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.

On 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: 418255.5
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.

On to step 9:
0 divided by 2 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 418255.5
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.

The final result is 418255.5 with a remainder of 0.0.
