Well, the conversion isn't accurate yet, but using your approach, here's 
another way to do it that allows you to easily grow the list of numerals 
to be converted:

def convert(b10number)

  numerals     = ['M','D','C','L','X','V','I']
  values       = [1000,500,100,50,10,5,1]
  implemented   = []
  conversion     = ""
  remainder     = b10number

  values.each do |this_value|
    if this_value > 1
      implemented << remainder/this_value
      remainder = remainder % this_value
    else
      implemented << remainder
    end
  end

  implemented.each_with_index do |this_many, indx|
    conversion += (numerals[indx] * this_many)
  end

  puts conversion
end

puts 'Howdy there, enter a number and I\'ll convert it to the older 
Roman Numeral fashion!'
argument = gets.chomp.to_i
convert argument
