To divide numbers in scientific notation, separate the powers of 10 and digits. Divide the digits normally and subtract the exponents of the powers of 10. By convention, the quotient is written such that there is only one non-zero digit to the left of the decimal. Consider (1.432×10 2) ÷ (800×10 -1) ÷ (0.001×10 5):
As another example, in radix 5, a string of digits such as 132 denotes the number 1 × 5² + 3 × 5¹ + 2 × 5⁰ = 42. This representation is unique. Let b be a positive integer greater than 1.
