450235 ÷ 2 
Our goal is to divide 450235 by 2.

Going ahead to step 1:
2 can be fit into 4 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 0 after subtracting 4 from 4.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 2

Step 2:
When dividing 5 by 2, we get 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 22.0
If we subtract 4 from 5, we get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 2

On to step 3:
2 goes into 10 5 times with 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.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 2

Moving on to step 4:
The number 2 fits into 2 1 times, leaving a remainder of 0.
The next digit of our result is 1. 
Result so far: 2251.0
Subtract 2 from 2 to get 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 2

On to step 5:
When dividing 3 by 2, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 22511.0
Subtract 2 from 3 to get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 2

On to step 6:
2 can be fit into 15 7 times, resulting in a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 225117.0
If we take 14 away from 15, 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.

Let's proceed to step 7:
The number 2 fits into 10 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 225117.5
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.

Moving on to step 8:
When dividing 0 by 2, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 225117.5
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.

Let's proceed to step 9:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 225117.5
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.

Our division results in 225117.5 with a remaining 0.0.
