Can you explain to me what exactly happens after each step?

You press ctrl-Z. The system suspends the running program, displays a job number and a "Stopped" message and returns you to a bash prompt. You type the "disown -h %1" command (here, I've used a "1", but you'd use the job number that was displayed in the "Stopped" message) which marks the job so it ignores the SIGHUP signal (it will not be stopped by logging out). Next, type the "bg" command using the same job number. This resumes the running of the program in the background and a message is displayed confirming that. You can now log out and it will continue running...

...You should be aware that when you use the "bg" command the result is the same as if you'd run your program in the background with an ampersand (&). It won't have any output to stdout so it should be made to write output to a file (nohup will redirect standard output to nohup.out or ~/nohup.out if you don't redirect it yourself).
