No, no need for an intermediate table. The multi-table insert (inserting multiple times into the same table, that is) probably does the job.
Alternatively
      insert into tableB
      select div,
                cust,
                case n
                    when 1 then jan
                    when 2 then feb
                    when 3 then mar
                 end
     from external table
              cross join (select 1 n from dual
                               union all
                               select 2 from dual
                               union all
                               select 3 from dual)
