decimal Decimal to binary algorithm

Is there a better way to code this specific algorithm using successively division through 2 which converts decimal numbers into binary numbers without calling a build inbuilt-in function?

print "Please enter a decimal number."
prompt = '>> '
dec_number = input(prompt)
dec_new = dec_number 
binstr = ''

'''dec2bin'''
while dec_new != 0:
  binstr += str(dec_new % 2)
  dec_new = dec_new // 2

print binstr[::-1]
