Narrative:

Operated aircraft X to ZZZ. Pushed back from gate; taxied and took off with no abnormalities. Proceeded en-route towards ZZZ; set up for the RNAV; briefed the approach and procedures and discussed the threats of the local terrain. Around 1.5-2NM from the FAF I called for gear down flaps 30. I watched the first officer (first officer) put the gear handle down and immediately noticed no noise associated with the gear lever coming down; as the first officer was selecting flaps 30 I made a comment that the gear was not down. About 5 seconds or more passed from the time the first officer selected gear down and we received the master warning and aural warning of 'gear disagree' all 3 gear were not deployed. I immediately started to level off and told the first officer we needed higher and vectors off the approach. He did so and stated our situation; ATC had us fly runway heading and climb to 4;000. As we climbed we cleaned up the aircraft except we left the gear handle down. Once level at 4;000 we pulled the gear handle up and I took over the radios having the first officer run the QRH for gear disagree page. While he ran the checklist I continued to talk to ATC; dispatch; flight attendants and passengers. After running the QRH checklist and no luck we decided to transfer the controls and radios to the first officer so that I could try the checklist. I started the checklist from the beginning and the message persisted referring us to [the next page]. I followed the procedures stated and the note to cycle the gear more than once with no luck. We then proceeded on with pulling the ldg gear man release lever to its full extension. Following those procedures and pulling the man release lever we were able to successfully bring all three gear down with the nose wheel taking around 5-10 seconds to deploy. After successfully bringing the gear down I informed the flight attendants our gear issue was resolved but our nose wheel steering may not work on the ground. I also informed the flights attendants to expect [prepare the cabin] and said I would give them ten minutes to prepare for landing again. I informed all the passengers what the extent of our mechanical issue was and assured them that all our indications appear to be normal again and we would make a normal landing. I informed the passengers that upon landing they will see emergency vehicles come up to the aircraft but not to be alarmed and also that at slow speeds our steering may not work so we will more than likely need to sit on the runway and be towed to the gate. After informing everyone on the aircraft I called dispatch to talk more in depth on our situation. We all agreed to make the approach into ZZZ and I would call them on the ground. We then informed ATC that we were ready for the approach not declaring an emergency but would like arff (airport rescue and fire fighting) on standby. Approach took fob (fuel on board) and souls on board. Upon touchdown we received the nose wheel steering inop caution; after the first officer called 90 knots we started to receive shimmy in the nose gear so we both pulled back on the yoke to relieve pressure off the nose and informed ATC we were stopping on the runway. After we stopped I informed the passengers to remain seated with their seatbelts fastened. We talked with arff and informed them our aircraft and its occupants were in good condition which they confirmed from the outside the aircraft was okay also. In the meantime tower called to have a tug come meet us on the runway and tug us back to the gate. While we waited for the tug the first officer and I ran the QRH and fault reset procedure for nose wheel steering inop with no luck. Once we saw ops and the tug enter the runway I informed the flight attendants and passengers they would be pulling us to the gate shortly. Upon getting to the gate all passengers appeared to be of good morale and appreciative. Our crew answered any and all questions they had as they deplaned. Once passengers deplaned I called and talked to dispatch; maintenance and the duty pilot answering all of their questions. We wrote the aircraft up for the gear disagree; unsuccessful fault reset procedure and an [system] fault. After talking with the local maintenance the first officer and I performed a thorough walk around the aircraft noting zero abnormalities and took multiple pictures of the gear. Both of us did not notice anything wrong or broken.

Proceeded en-route towards ZZZ; set up for the RNAV; briefed the approach and procedures and discussed the threats of the local terrain. Around 1.5-2NM from the FAF I called for gear down flaps 30.
