Article: In 1906, the franchise recorded a Major League record 116 wins (tied by the 2001 Seattle Mariners) and posted a modern-era record winning percentage of .763, which still stands today. They appeared in their first World Series the same year, falling to their crosstown rivals, the Chicago White Sox, four games to two. The Cubs won back-to-back World Series championships in 1907 and 1908, becoming the first Major League team to play in three consecutive Fall Classics, and the first to win it twice. The team has appeared in seven World Series following their 1908 title, most recently in 1945. The Cubs have not won the World Series in 107 years, the longest championship drought of any major North American professional sports team, and are often referred to as the "Lovable Losers" because of this distinction. They are also known as "The North Siders" because Wrigley Field, their home park since 1916, is located in Chicago's North Side Lake View community at 1060 West Addison Street. The Cubs have a major rivalry with the St. Louis Cardinals.

Question: What is the winning percentage the Cubs posted that still stands today?
