• ans is 337.
  77777,77777.....(upto 101 digits can be written as below)
  ==>700000...(zeros up to 101)+7000...(0 s upto 100)+700....(0 s upto 99)..+700+77+7
  for every number such that start with 7 and have three or more zeros remainder will be 400 when divide by 440, for example
  7000000%440=400,7000%440=400,70000%440=400,ans so on
  so reaminder will be (99*400+777)%440=40377
  ===>40377%440=337
