To solve this problem, we need to simplify the given mathematical expressions and then compare the results to arrange them from least to greatest. Let's break down each of the provided expressions.

1. **First Expression**: 
   \[
   (4.27 \times 10^8) \cdot (9.2 \times 10^{-5})
   \]
   To multiply, we combine the constants and powers of 10:
   \[
   4.27 \times 9.2 = 39.284
   \]
   For the powers of 10:
   \[
   10^8 \times 10^{-5} = 10^{8 + (-5)} = 10^3
   \]
   So the result is:
   \[
   39.284 \times 10^3 = 3.9284 \times 10^4
   \]

2. **Second Expression**:
   \[
   (6.96 \times 10^5) \cdot (8.43 \times 10^{-2})
   \]
   Multiplying the constants:
   \[
   6.96 \times 8.43 = 58.6728
   \]
   For the powers of 10:
   \[
   10^5 \times 10^{-2} = 10^{5 - 2} = 10^3
   \]
   So the result is:
   \[
   58.6728 \times 10^3 = 5.86728 \times 10^4
   \]

3. **Third Expression**:
   \[
   \frac{(7.25 \times 10^6)}{(9.36 \times 10^{-7})}
   \]
   Dividing the constants:
   \[
   7.25 \div 9.36 = 0.77479
   \]
   For the powers of 10:
   \[
   10^6 \div 10^{-7} = 10^{6 - (-7)} = 10^{13}
   \]
   So the result is:
   \[
   0.77479 \times 10^{13} = 7.7479 \times 10^{12}
   \]

4. **Fourth Expression**:
   \[
   \frac{(8.32 \times 10^4)}{(9.67 \times 10^1)}
   \]
   Dividing the constants:
   \[
   8.32 \div 9.67 = 0.8607
   \]
   For the powers of 10:
   \[
   10^4 \div 10^1 = 10^{4 - 1} = 10^3
   \]
   So the result is:
   \[
   0.8607 \times 10^3 = 8.607 \times 10^2
   \]

5. **Fifth Expression**:
   \[
   \frac{(1.89 \times 10^4)}{(5.92 \times 10^3)}
   \]
   Dividing the constants:
   \[
   1.89 \div 5.92 = 0.31926
   \]
   For the powers of 10:
   \[
   10^4 \div 10^3 = 10^{4 - 3} = 10^1
   \]
   So the result is:
   \[
   0.31926 \times 10^1 = 3.1926
   \]

Now, let’s arrange the results from least to greatest:

1. \( 3.1926 \)
2. \( 8.607 \times 10^2 \)
3. \( 3.9284 \times 10^4 \)
4. \( 5.86728 \times 10^4 \)
5. \( 7.7479 \times 10^{12} \)
