Division

Ruby:

def divide(n1, n2):
	if n1 == 0:
		raise  ZeroDivisionError
	elif n1 == 1: 
		return n2
	elif n1 < 0: 
		print ' should be bigger than 0'
	elif n2 <= 1:
		return 0
	else:
		return divide(n1, n2-n1) + 1

Ruby:


def divide(n1, n2)
	if n1 == 0
		raise ZeroDivisionError
	elsif n1 == 1
		return n2
	elsif n1 < 0: 
		print 'n1 should be bigger than 0'
	elsif n2 <= 1
		return 0
	end
	return divide(n1, n2-n1) + 1

end 

Elixir: 

defmodule Math do
  def divide(n1, n2) do
     cond do
       n1 == 0 ->
         0
       n1 == 1 ->
         n2
       n1 < 0 ->
         "Denominator should be bigger than 0"
       n2 <= 1 ->
         0
       true ->
         divide(n1, n2-n1) + 1
      end

  end
end

Golang: 

func divide(n1 int, n2 int) int {

    if n1 == 0 {
        return 0
    } else if (n1 < 0 ) {
        return 0
    } else if (n1 == 1) {
        return n2
    } else if (n2 <= 1) {
        return 0
    }

    return divide(n1, n2-n1) +1
}
