input: Write a function to find all the numbers divisible by a certain number within a certain range.
  
  Input:
  int m=36, int n=74, int divisor=6
  
  Output:
  def find_numbers_divisible_by(m, n, divisor):
      divisible_numbers = []
      for i in range(m, n+1):
          if i % divisor == 0:
              divisible_numbers.append(i)
      return divisible_numbers
  assert find_numbers_divisible_by(36, 74, 6)==[36, 42, 48, 54, 60, 66, 72]
  assert find_numbers_divisible_by(20, 30, 4)==[20, 24, 28]
  assert find_numbers_divisible_by(1, 10, 2)==[2, 4, 6, 8, 10]
  assert find_numbers_divisible_by(0, 5, 1)==[0, 1, 2, 3, 4, 5]
  assert find_numbers_divisible_by(15, 25, 7)==[21]
output: def find_numbers_divisible_by(m, n, divisor):
      divisible_numbers = []
      for i in range(m, n+1):
          if i % divisor == 0:
              divisible_numbers.append(i)
      return divisible_numbers
