We divide 842867 by 2
Let's see how many times 2 fits into 842867.

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
Deduct 8 from 8 and we're left with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 2

Moving on to step 2:
If we divide 4 by 2, we get 2 and a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Subtract 4 from 4 to get 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 2

Let's proceed to step 3:
2 divided by 2 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 421.0
The remainder is 0 after subtracting 2 from 2.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 2

Step 4:
The number 2 fits into 8 4 times, leaving a remainder of 0.
The next digit of our result is 4. 
Result so far: 4214.0
If we subtract 8 from 8, we get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 2

Going ahead to step 5:
When dividing 6 by 2, we get 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 42143.0
Subtract 6 from 6 to get 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 2

Advancing to step 6:
7 divided by 2 is 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 421433.0
Subtracting 6 from 7 leaves us 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.

Going ahead to step 7:
2 goes into 10 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 421433.5
If we take 10 away from 10, 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.

Going ahead 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: 421433.5
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.

Step 9:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 421433.5
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.

The final result is 421433.5 with a remainder of 0.0.
