input: Write a Python function that takes two tuples and returns a tuple containing the element-wise quotients.
  assert elementwise_divide((10, 4, 6, 9),(5, 2, 3, 3)) == (2, 2, 2, 3)
  assert elementwise_divide((12, 6, 8, 16),(6, 3, 4, 4)) == (2, 2, 2, 4)
  assert elementwise_divide((20, 14, 36, 18),(5, 7, 6, 9)) == (4, 2, 6, 2)
output: def elementwise_divide(tuple1, tuple2):
      return tuple(a // b for a, b in zip(tuple1, tuple2))
