A little girl has learned how to write digits. So far, she knows only: one, two,
three and four. She took a piece of paper and wrote five of each digit to make a huge
number. She came to her Daddy and said, “When I will grow up, I'll buy as many
chocolate bars as this number tells and we'll split them among you, Mommy, and
me!" But her Daddy answered, “It will not work; there will be a remainder.” What is
the remainder?
