406629 ÷ 2 
Our goal is to divide 406629 by 2.

Let's proceed to step 1:
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: 2.0
The remainder is 0 after subtracting 4 from 4.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 2

Going ahead to step 2:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we take 0 away from 0, 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 3:
2 can be fit into 6 3 times, resulting in a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 203.0
Subtracting 6 from 6 leaves us with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 2

Moving on to step 4:
6 divided by 2 is 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 2033.0
Subtracting 6 from 6 leaves us with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 2

On to step 5:
If we divide 2 by 2, we get 1 and a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 20331.0
If we subtract 2 from 2, we get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 2

On to step 6:
When dividing 9 by 2, we get 4 with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 203314.0
If we take 8 away from 9, we end up 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.

Step 7:
2 goes into 10 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 203314.5
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.

On 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: 203314.5
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.

Going ahead to step 9:
If we divide 0 by 2, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 203314.5
If we take 0 away from 0, 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.

The final result is 203314.5 with a remainder of 0.0.
