Narrative: During climbout we deviated multiple times to avoid convective buildups; which is normal and air traffic control helped us greatly. We experienced intermittent light turbulence in the climb as we deviated around heavy precipitation and convective cloud build ups that we were observing on weather radar.Our filed altitude was 41;000 feet; we were cleared to climb to 40;000 feet and were informed we would be cleared to climb once we were clear of some conflicting traffic.We leveled off at 40;000 feet and were clear of the convective thunderstorm buildups but were still in Instrument Meteorological Conditions (IMC). FO and I were discussing potentially climbing to 45;000 to get on top of the IMC. Approximately 30 minutes into the flight as we were level at 40;000 feet I heard a pop; looked up and saw the right forward windscreen was completely shattered. FO noticed it at the same time and I said get our oxygen masks on immediately. We donned our masks; advised ATC and asked for a descent and requested a diversion to the nearest airport with emergency services. Air traffic informed us it was ZZZ and we elected to divert there. We informed our passengers of the situation; to please be seated with the seat belts securely fastened and requested that if the oxygen masks deploy to please don them. I continued flying the aircraft as FO ran the QRH Emergency Checklist for a shattered windshield. FO then set up our flight management system for approach and landing into ZZZ as I guided us in.The rest of the descent; approach and landing went without incident.

Synopsis: Gulfstream G280 flight crew reported that the First Officer's windshield shattered at top of climb; causing a diversion and precautionary landing.
