input: Write a Python function to determine the frequency of a specific character in a string that is repeated.  
  assert count_Char("abcac", 'a') == 4  
  assert count_Char("abca", 'c') == 2  
  assert count_Char("aba", 'a') == 7
output: def count_Char(s, char):
      n = len(s)
      char_count = s.count(char)
      full_repeats = 10**6 // n
      remainder = 10**6 % n
      total_count = full_repeats * char_count + s[:remainder].count(char)
      return total_count
