How can I disown a running process and associate it to a new screen shell?

I have a running program on a SSH shell. I want to pause it and be able to unpause its execution when I come back.

One way I thought of doing that was to transfer its ownership to a screen shell, thus keeping it running in there.

Is there a different way to proceed?

• Using or administering a *nix desktop or server
• The Unix foundation underlying MacOS (but generally not frontend application questions)
• The underlying *nix OS on an embedded system or handheld device (e.g. an Android phone)
• Shell scripting
• Applications packaged in *nix distributions (note: being cross-platform does not disqualify)
• UNIX C API and System Interfaces ( within reason )
