The Hubble was launched in April 1990. Since launch it's had 5 servicing missions, the last being in May 2009, which means the average time between servicings was slightly under four years. The longest time was between the fourth and fifth missions ... about seven years.
The Hubble is projected to remain operational until 2014. It's unlikely that there will be another servicing mission, unless the final deorbiting is counted. This will probably happen sometime between the end of its useful life and 2025, by which time it will be in severe danger of experiencing an uncontrolled reentry. This would be bad, since the Hubble is quite large for a satellite and there's a good possibility that substantial chunks of it will survive reentry and impact the Earth's surface. A controlled deorbit will allow it to be brought down safely in the middle of the ocean as opposed to, say, over Los Angeles or Tokyo or London.
The last servicing mission installed a docking ring to allow a future unmanned robotic spacecraft to dock with the Hubble and deorbit it.
