No, this is not possible. The image data isn't there, so all you can do is extrapolate based on the pixels you have, which is what paint.net does.

Quite correct. You're trying to paint your whole house with one test pot. There just isn't enough material for the job.

Regardless of the resampling algorithm used you're still interpolating to create data that wasn't there before.

No it isn't possible.

You've enlarged the image by a factor of 8.7.  Expect it to be blurry and low quality because each pixel in the original has been stretched to cover almost 76 pixels in the enlarged image.
