Certainly! Let's solve each of the division problems step by step.

### a) $$ 8700 \div 60 $$

**Solution:**
$$
8700 \div 60 = \frac{8700}{60}
$$
Simplify by dividing both numerator and denominator by 60:
$$
\frac{8700 \div 60}{60 \div 60} = \frac{145}{1} = 145
$$

**Answer:** $$ 145 $$

### b) $$ 34719 \div 71 $$

**Solution:**
$$
34719 \div 71 = \frac{34719}{71}
$$
Perform the division:

1. $$71 \times 400 = 28400$$
2. $$34719 - 28400 = 6319$$
3. $$71 \times 80 = 5680$$
4. $$6319 - 5680 = 639$$
5. $$71 \times 9 = 639$$

Add up the multiples:
$$
400 + 80 + 9 = 489
$$

**Answer:** $$ 489 $$

### c) $$ 208640 \div 160 $$

**Solution:**
$$
208640 \div 160 = \frac{208640}{160}
$$
Simplify by dividing numerator and denominator by 10:
$$
\frac{20864}{16}
$$
Now, divide 20864 by 16:
$$
20864 \div 16 = 1304
$$

**Answer:** $$ 1304 $$

---

### d) $$ 102024 \div 156 $$

**Solution:**
$$
102024 \div 156 = \frac{102024}{156}
$$
Simplify by dividing numerator and denominator by 12:
$$
\frac{8502}{13}
$$
Now, divide 8502 by 13:
$$
8502 \div 13 = 654
$$

**Answer:** $$ 654 $$

---

### Summary of Answers:
- **a)** $$ 145 $$
- **b)** $$ 489 $$
- **c)** $$ 1304 $$
- **d)** $$ 654 $$
The answers are: - a) 145 - b) 489 - c) 1304 - d) 654

a) \( 8700 \div 60 \) (b) \( 34719 \div 71 \) c) \( 208640 \div 160 \) (d) \( 102024 \div 156 \)
