input: Write a python function to search through a list and return all elements which are divisible by 5.
  assert find_division_by_5([4, 9, 5, 20, 21, 33]) == [5, 20]
  assert find_division_by_5([10, 15, 22, 35, 40]) == [10, 15, 35, 40]
  assert find_division_by_5([1, 2, 3, 4, 6, 7, 8]) == []
output: def find_division_by_5(lst):
      return [x for x in lst if x % 5 == 0]
