Dividing and Scientific Notation

The video tutorial explains how to divide numbers using scientific notation. It covers three examples: dividing 0.0016 by 400,000, 3.6 * 10^8 by 6 * 10^-2, and 1.5 by 3. Each example demonstrates converting numbers to scientific notation, performing the division, and ensuring the result is in proper scientific notation. The tutorial emphasizes handling whole numbers and exponents separately and adjusting the decimal point to maintain scientific notation format.
