<bot>: Here is a Python program to extract bits of large numbers

import math

def extract_bits(number, bit_count):
  """Extract the bit string of a number."""
  return number.bit_length() - bit_count

# Enter the number
number = 123456789

# Calling the function
print((extract_bits(number, 10)))

#Example Output
# 17
