868556 ÷ 2 
We want to divide 868556 by 2.

Let's proceed to step 1:
If we divide 8 by 2, we get 4 and a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 8 away from 8, we end up with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 2

Let's proceed to step 2:
2 can be fit into 6 3 times, resulting in a remainder of 0.
The next digit of our result is 3. 
Result so far: 43.0
If we subtract 6 from 6, we get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 2

Going ahead to step 3:
The number 2 fits into 8 4 times, leaving a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 434.0
Subtract 8 from 8 to get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 2

Let's proceed to step 4:
2 can be fit into 5 2 times, resulting in a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 4342.0
If we take 4 away from 5, we end up with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 2

Let's proceed to step 5:
The number 2 fits into 15 7 times, leaving a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 43427.0
If we take 14 away from 15, we end up with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 2

On to step 6:
2 goes into 16 8 times with a remainder of 0.
The next digit of our result is 8. 
Result so far: 434278.0
The remainder is 0 after subtracting 16 from 16.
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 7:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 434278.0
Subtract 0 from 0 to 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.

Going ahead to step 8:
If we divide 0 by 2, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 434278.0
Subtracting 0 from 0 leaves us 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 434278.0 and a remainder of 0.0.
