We look at the division of 450221 by 2 
We want to figure out the number of times 450221 can be divided by 2.

Let's proceed to step 1:
When dividing 4 by 2, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 4 away from 4, we end up with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 2

On to step 2:
When dividing 5 by 2, we get 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we subtract 4 from 5, we get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 2

Going ahead to step 3:
2 can be fit into 10 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 225.0
Deduct 10 from 10 and we're left with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 2

On to step 4:
2 goes into 2 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 2251.0
If we take 2 away from 2, we end up with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 2

On to step 5:
The number 2 fits into 2 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 22511.0
Deduct 2 from 2 and we're left with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 2

Let's proceed to step 6:
2 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 225110.0
Subtracting 0 from 1 leaves us 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:
10 divided by 2 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 225110.5
Subtract 10 from 10 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.

Moving on to step 8:
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: 225110.5
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.

Step 9:
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: 225110.5
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 225110.5 with a balance of 0.0.
