We're dividing 400810 by 2 
Our goal is to divide 400810 by 2.

Let's proceed to step 1:
2 can be fit into 4 2 times, resulting in a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 4 from 4 and we're left with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 2

Advancing to step 2:
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: 20.0
Deduct 0 from 0 and we're left with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 2

Step 3:
0 divided by 2 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 200.0
If we take 0 away from 0, we end up with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 2

Step 4:
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: 2004.0
If we subtract 8 from 8, we get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 2

Advancing to step 5:
2 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 20040.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 2

Step 6:
If we divide 10 by 2, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 200405.0
The remainder is 0 after subtracting 10 from 10.
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: 200405.0
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.

Going ahead to step 8:
If we divide 0 by 2, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 200405.0
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.

In conclusion, the division gives 200405.0 with a balance of 0.0.
