To solve the expression $\frac{1.19 \times 10^{12}}{3.2 \times 10^7}$, follow these steps:

1. Divide the numerical coefficients: $\frac{1.19}{3.2} \approx 0.371875$

2. Subtract the exponents: $10^{12} \div 10^7 = 10^{(12 - 7)} = 10^5$

3. Combine the results: $0.371875 \times 10^5$

4. Express in scientific notation: $0.371875 \times 10^5 = 3.71875 \times 10^4$

So, $\frac{1.19 \times 10^{12}}{3.2 \times 10^7} = 3.71875 \times 10^4$.
