When and how was Khorasan province divided?

Until September 2004, Khorasan was Iran's largest province, encompassing the western portion of the historical Greater Khorasan region. It was formally divided into three separate administrative entities—North Khorasan, South Khorasan, and Razavi Khorasan—following legislative approval by Iran's parliament and Council of Guardians in May 2004. This division took effect on September 29, 2004.
