In time your circumstances may change, you can speak to her over the phone whenever you are away, so she is still used to your presence even if you are not actually there.

Well, since you have so little time to spend with her, try to have a camera always by your side every time you're with her. Take photos of you and your daughter together, at least even though your time with her is minimal, you will be able to remember those times very clearly because of the photos even in the years to come.

And don't feel that bad about being away, you are only away because you are a great dad who works so he can provide for his family. You are doing exactly what a good father should be doing.
