Let's divide 451040 by 2
Let's see how many times 2 fits into 451040.

Let's proceed to step 1:
When dividing 4 by 2, we get 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 4 from 4 leaves us with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 2

Moving on to step 2:
The number 2 fits into 5 2 times, leaving a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 22.0
If we take 4 away from 5, we end up with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 2

Let's proceed to step 3:
2 can be fit into 11 5 times, resulting in a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 225.0
Subtracting 10 from 11 leaves us with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 2

Advancing to step 4:
10 divided by 2 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 2255.0
If we subtract 10 from 10, we get 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 2

On to step 5:
The number 2 fits into 4 2 times, leaving a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 22552.0
The remainder is 0 after subtracting 4 from 4.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 2

On to step 6:
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: 225520.0
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.

Advancing to step 7:
If we divide 0 by 2, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 225520.0
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.

Going ahead to step 8:
2 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 225520.0
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.

The final result is 225520.0 with a remainder of 0.0.
