Can you do this in Windows?

Today i happened to use the ubuntu calculator application to do some minor calculation.
I was trying to calculate the size of a file in megabytes.(which i intended to download)

This is what i wanted to calculate:
496890302/(1024*1024)

Normally, in windows, I use to do something like this:

1. Type 496890302


2. Type/press "/"

3. Type 1024



4. Type/press "/"



5. Type 1024

6. Type/press "="



Ooohhh...

6 steps for a simple operation....!!

And how about this...?

Step 1:



Step 2: Type/press "="



Unknowingly, I've been doing this many times so far in windows. What a waste of time..?

NOTE:
And one more thing..
When you take a screenshot in windows (by pressing alt+printscreen), it's just copied to clipboard. Then you need to open an application like "Paint" or "IrfanView" to save the screenshot to a file. And the default format used by "Paint" (in my case) is "bmp". Because of that, the size of the 4 windows calculator screenshots i posted above is about 2.9 MB.

When you take a screenshot in ubuntu (by pressing alt+printscreen), it prompts you to save the screenshot to a file. And it uses the "png" format to save the screenshots. As a result, the 2 ubuntu-calculator screenshots i posted above are about 45 KB only.

(Yes, it's true that if I save using "png" format in windows by using some good tools like IrfanView, then i can get reduced file size. But in this post, i tried to explain the default behaviour of both operating systems)
