You can't. You are scaling it up 8x. Sharpness/detail is information. You have much less information in a 180Kpix image that in a 11Mpx one (8x8=64 times more pixels). So your big image is either blurry of pixellated, because you can't create information out of nothing(*). If it were not so, all images could be scaled down to 1x1 pixel for storage, right?
(*) there are applications that can enlarge pictures by trying to synthesize textures. They have been around for years, but since they don't pop out everywhere they possibly do not work that well.
