If you are a regular passport holder and are looking to get short-term Russian visa Tourist, Private, Student, Business, Humanities, Transit or Work, you need to apply in a Russian Visa Application Center, not at the Consulate. This does not apply to those holding diplomatic and service passports.
The first thing to do is to check the requirements for your visa. You can do this on the website of the Visa Center. When all necessary documents are collected, you can fill out a visa application form. Please note that this form may only be completed online, the handwritten form is not acceptable.
Part destination, date and details of organizations invited to the application form must be completed in accordance with the details of the invitation or travel vouchers.

When it comes to questions about the countries you have visited in the last ten years, you can mention only the countries that are stamped passport upon arrival/departure. Also, you can mention only your last visit to a country where you are traveling a few times; you do not need to list all year when you visit the same countries except Russia.
In previous work and study part, you do not need to enter an exact address, a city (town) and the state will be enough. If you do not remember the phone number of these organizations, you can put "00000000000".
In case you have not studied or worked anywhere, you have to provide an additional letter confirming that. The letter should be addressed to the Russian Embassy and can be written in a free format.
