Let's go through each of the expressions and solve them step by step using the division rule for scientific notation:

\[
\frac{A \times 10^m}{B \times 10^n} = \frac{A}{B} \times 10^{m-n}
\]

### Solutions:

1. **\( 8 \times 10^8 \div 2 \times 10^4 \)**  
   \[
   \frac{8}{2} \times 10^{8-4} = 4 \times 10^4
   \]

2. **\( 8 \times 10^{12} \div 8 \times 10^9 \)**  
   \[
   \frac{8}{8} \times 10^{12-9} = 1 \times 10^3
   \]

3. **\( 9 \times 10^6 \div 3 \times 10^3 \)**  
   \[
   \frac{9}{3} \times 10^{6-3} = 3 \times 10^3
   \]

4. **\( 5 \times 10^{-8} \div 1 \times 10^{-4} \)**  
   \[
   \frac{5}{1} \times 10^{-8 - (-4)} = 5 \times 10^{-4}
   \]

5. **\( 6 \times 10^{-7} \div 2 \times 10^{-2} \)**  
   \[
   \frac{6}{2} \times 10^{-7 - (-2)} = 3 \times 10^{-5}
   \]

6. **\( 1 \times 10^6 \div 2 \times 10^3 \)**  
   \[
   \frac{1}{2} \times 10^{6-3} = 0.5 \times 10^3
   \]
   Alternatively, writing in proper scientific notation:  
   \[
   5 \times 10^2
   \]
