621302 ÷ 2 
We want to figure out the number of times 621302 can be divided by 2.

Advancing to step 1:
If we divide 6 by 2, we get 3 and a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 6 away from 6, we end up with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 2

On to step 2:
When dividing 2 by 2, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 31.0
If we subtract 2 from 2, we get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 2

Moving on to step 3:
1 divided by 2 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 310.0
If we take 0 away from 1, we end up with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 2

On to step 4:
2 can be fit into 13 6 times, resulting in a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 3106.0
Deduct 12 from 13 and we're left with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 2

Moving on to step 5:
10 divided by 2 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 31065.0
Deduct 10 from 10 and we're left with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 2

Let's proceed to step 6:
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: 310651.0
If we subtract 2 from 2, 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.

Moving on to step 7:
If we divide 0 by 2, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 310651.0
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 8:
When dividing 0 by 2, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 310651.0
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.

The final result is 310651.0 with a remainder of 0.0.
