Can someone tell me (step by step) how to calculate the Norton's resistance for this circuit? (see picture below)

Simpler example for you to extrapolate from:

** Using Norton here is silly and time wasting.
It is simply a parallel resistor problem.
- RL plus R3 parallel R 5 - so compute the combined value.
- This value plus R2 parallel R4 - so compute the value.
- Add this to R1.

You can simplify this circuit a lot by applying the rules for parallel and series resistors repeatedly.

treat the voltage source as a short circuit (or as a fixed resistor if it has non-zero resistance) and solve for the resitance at the part that interests you (this would be the output terminals)
It's not clear from the OP's problem statement that RL should be included in the Norton resistance, or just the network up to RL leaving a Norton equivalent driving the load.
You are lucky today. Usually its not easy to get someone to do your homework for you.

Exactly so. Norton's theorem applies to a two-terminal device consisting of voltage sources and resistors. Tell us _which_ two terminals of the seven, or there isn't any soluble problem presented.
Current source, actually. A Thevenin equivalent would include a voltage source.
