Sometimes, they will work together to jointly introduce legislation with other Senators.  Senators can also collaborate with members of the House of Representatives on legislation so that identical or very similar bills are introduced in both the House and the Senate.

The Senator or Senators who introduce the bill are known as sponsors and they are the primary champions of the legislation. Other Senators, who did not introduce the legislation themselves but who also want to express strong support for the bill, can sign on as a cosponsor.  

After being introduced, the bill is sent to the Senate Parliamentarian who assigns it to a specific committee or committees for further deliberation.

When a bill is introduced, the Senate Parliamentarian is responsible for deciding which Committee should review the legislation.

The chair of the committee may decide to hold a hearing in order to examine the legislation.

During a hearing, committee members invite policy experts, agency representatives, and other stakeholders to testify on how the bill will affect the country. 

After holding a hearing or hearings, the chair of the committee can decide to hold a "markup" during which committee members debate, modify, and ultimately vote for or against the bill.  If the majority of the committee members vote favorably for the bill, it is advanced to the Senate floor, where every Senator has an opportunity to review and debate the legislation.

Sometimes, less controversial pieces of legislation will be included in related larger bills as amendments in order to help speed up the legislative process.
