number = 1234567890
num_string = number.to_s
num_array = []
work_array = []

num_string.each_char {|c| num_array.push(c)}

for i in 0..4
  work_array.push(num_array.shift.to_i)
end

work_array.each {|i| puts "#{i} is #{work_array[i].class}"}

no reason to convert integer to string, just wrap it in quotes

num_string = "1234567890"

using the .split method will convert a string of characters into an array

num_array = num_string.split("")

use map to convert the array of strings into integers and store in a new variable

work_array = num_array.map { |num| num.to_i}

work_array.each { |i| puts "#{i} is #{i.class}"}
