 * A Rail Problem
 * There is a garden railing similar to our design.

 * In each division between two uprights there is an equal number of ornamental rails,
 * and a rail is divided in halves and a portion stuck on each side of every upright,
 * except that the uprights at the end have not been given half rails.
 * Idly counting the raise from one end to another, we found that there were $1223$ rails, counting two halves as one rail.
 * We also noticed that the number of those divisions was five more than twice the number of whole rails in a division.
 * How many rails were there in each division?
