1. **State the problem:** We need to divide 0.072 by 0.00050.
2. **Recall the division rule:** Dividing two decimals can be simplified by converting the divisor to a whole number.
3. **Convert divisor to whole number:** Multiply numerator and denominator by 100000 (to move decimal 5 places right in denominator):
$$\frac{0.072}{0.00050} = \frac{0.072 \times 100000}{0.00050 \times 100000} = \frac{7200}{50}$$
4. **Simplify the fraction:**
$$\frac{7200}{50} = 144$$
5. **Interpretation:** Dividing 0.072 by 0.00050 equals 144.
**Final answer:**
$$0.072 \div 0.00050 = 144$$
