Sure, let's estimate each of the given calculations by rounding the numbers to make the computations simpler.

---

**a) $$ 1899 \div 21 $$**

**Estimation Steps:**
1. **Round the numbers:**  
   - **1899** is close to **1890** (since 1890 is a multiple of 21).  
   - **21** remains unchanged.

2. **Divide the rounded numbers:**  
   $$
   1890 \div 21 = 90
   $$

**Estimated Answer:**  
$$
1899 \div 21 \approx 90
$$

**c) $$ 2895 \times 110 $$**

**Estimation Steps:**
1. **Round the numbers:**  
   - **2895** is rounded to **2900** for easier multiplication.  
   - **110** can be broken down into **100 + 10**.

2. **Multiply using the distributive property:**  
   $$
   2900 \times 100 = 290{,}000
   $$
   $$
   2900 \times 10 = 29{,}000
   $$
   
3. **Add the two results together:**  
   $$
   290{,}000 + 29{,}000 = 319{,}000
   $$

**Estimated Answer:**  
$$
2895 \times 110 \approx 319{,}000
$$

**e) $$ 200{,}000 \div 25 $$**

**Estimation Steps:**
1. **Recognize that 200,000 is divisible by 25:**  
   $$
   200{,}000 \div 25 = 8{,}000
   $$

*(Since $$25 \times 8{,}000 = 200{,}000$$)*

**Estimated Answer:**  
$$
200{,}000 \div 25 \approx 8{,}000
$$

---

These estimations provide a quick and efficient way to approximate the results without performing exact calculations.
- $$ 1899 \div 21 \approx 90 $$ - $$ 2895 \times 110 \approx 319,000 $$ - $$ 200,000 \div 25 \approx 8,000 $$
