Let's divide 819843 by 2
Let's see how many times 2 fits into 819843.

Let's proceed to step 1:
8 divided by 2 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 8 away from 8, we end up with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 2

On to step 2:
2 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 2

Step 3:
When dividing 19 by 2, we get 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 409.0
Subtracting 18 from 19 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 2

On to step 4:
18 divided by 2 is 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 4099.0
The remainder is 0 after subtracting 18 from 18.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 2

Going ahead to step 5:
The number 2 fits into 4 2 times, leaving a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 40992.0
Deduct 4 from 4 and we're left with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 2

Moving on to step 6:
2 goes into 3 1 times with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 409921.0
Deduct 2 from 3 and we're left 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.

On to step 7:
The number 2 fits into 10 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 409921.5
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.

Let's proceed to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 409921.5
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.

Step 9:
2 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 409921.5
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.

Our division results in 409921.5 with a remaining 0.0.
