Registration in Russia on a 90 days business visa

1. Please see Russia visa registration when staying on the move, if you are on the move and have proof of travel such as ticket, the counter is reset every time.

2-3. Unfortunately I have no idea.

4. It is not complicated and time-consuming (I think it would take around half an hour), but it requires an owner of some livable property to register you on their premises. Not all hosts can do this for you if they rent and/or do not want to bother with bureaucracy.

5. Registration has beginning date and end date. Once it ended, you have e.g. 7 days to leave this location or register again, you can theoretically be in trouble after that. I think hotels will register you for the duration of your stay.

I travelled to Russia on a business visa in 2011 (as a tourist) as it had multiple entry, and a longer time.

I had to register at hotels, although some didn't like doing it, but it's fairly straight-forward.

I was asked once by police to see all my documents. Again though, this is easy to deal with - just keep your tickets/evidence of your accommodation and you can show it 'reset'. Note that I seem to remember you had to still register at least once a week or something, even if you keep moving. Frustrating.

Since I’m planning to live in different cities by hitchhiking, how can I register ”registration within 7 days stuff?”

You're supposed to register with the hotel or person(s) you stay with. You cannot register yourself. A Russian entity must register you, whether it be a hotel, apartment owner or friends/family you stay with.

Has anyone been stopped by police and had their registration checked?

I haven't experienced it but it's entirely possible and could happen. Technically Russian officials are not supposed to check your registration documents, only your passport and visa. Your registration documents are tied to the entity that sent your invitation letter, and they are on the hook for your registration.

Has anyone been traveling on a business visa like me as well?

Yes, many people travel to Russia on business visas. It's normal.

How is the process of registration? Is it complicated and time consuming?

It depends on who is registering you. A hotel can do it easily, whereas an Air Bnb or person would need to register you at the post office nearby, which is more time consuming than a hotel who just can stamp your paper. I have registered at hotels (like the Hilton and Kuznetskiy Inn) in Moscow, Hotel Mercure Sochi Centre and have also registered with my wife's family at the post office.

In my experiences, hotels are definitely much faster than if you go down to the post office and stand in the lines. The hotels will usually register you for free (as a service to paying customers), whereas going down to the post office costs a small fee. Every time I check into a Russian hotel, I make them register me and put the paper in my passport, so I know if I get stopped and searched, I can at least prove I tried to follow the rules. A Russian hotel will have their own stamp with their details that they will use on your paper. They simply stamp it and fill out their details and your details. At the hotel it usually takes about 5 minutes, if that long. When my wife took me to the post office, that took about 30 minutes because the postal workers are not the fastest.

No one talk about the valid time for the registration; for example, if I was planning to stay in whatever which city for 10 days, but then I stayed for 20 days, do I need to register again? Even though I stay in the same city?

No, you do not need to re-register in the same city. The purpose of registration is to see your migration pattern on a per city basis. They want to know what city you intend to be in, at all times.

Or is it so that with registration in a city, it doesn’t matter how many days you stay? It's just a proof that I’m actually visiting there?

Exactly. Registration is intended per city or town you intend to stay in. If you visit a town or city for the day, you do not need to register. Keep in mind, you have up to 7 days to register in any new city or town you migrate to and stay in.

For instance, if you initially register in Moscow but visit Saint Petersburg for less than 7 days, you only need to register in Moscow. Technically you should register in Saint Petersburg, but since you have 7 days to complete it, you technically do not have to.

Also keep in mind the Russian holidays. Whenever I visit Russia, it's during New Years and Christmas (Jan 7th) and these holidays significantly affect the business hours for post office and the business days required for calculation of registration days.
