We look at the division of 403834 by 2 
We want to divide 403834 by 2.

On to step 1:
2 goes into 4 2 times with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 4 from 4 to get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 2

Let's proceed to step 2:
2 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 20.0
Subtract 0 from 0 to get 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 2

Going ahead to step 3:
If we divide 3 by 2, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 201.0
Subtracting 2 from 3 leaves us with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 2

Going ahead to step 4:
2 goes into 18 9 times with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 2019.0
The remainder is 0 after subtracting 18 from 18.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 2

Advancing to step 5:
If we divide 3 by 2, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 20191.0
If we take 2 away from 3, we end up with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 2

Advancing to step 6:
If we divide 14 by 2, we get 7 and a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 201917.0
If we take 14 away from 14, 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.

Step 7:
0 divided by 2 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 201917.0
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.

Advancing 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: 201917.0
The remainder is 0 after subtracting 0 from 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 outcome is 201917.0, with a leftover of 0.0.
