To find the best estimate for \(365 \div 4\), let's analyze each option and see which one gives a close and convenient answer:

1. **Option A:** Round 365 to 400, then estimate \(400 \div 5\).
   - \(400 \div 5 = 80\).

2. **Option B:** Round 365 to 360, then estimate \(360 \div 4\).
   - \(360 \div 4 = 90\).

3. **Option C:** Round 365 to 350, then estimate \(350 \div 5\).
   - \(350 \div 5 = 70\).

4. **Option D:** Round 365 to 400, then estimate \(400 \div 4\).
   - \(400 \div 4 = 100\).

### Conclusion:
The correct choice is **Option B**, which rounds 365 to 360 and divides by 4, resulting in 90. This is a close and reasonable estimate for \(365 \div 4\), which is exactly 91.25.
