In scientific notation, when the exponent is negative, it means that the decimal point needs to be moved to the left. The absolute value of the exponent tells us how many places to move the decimal point. Thus, 5.23 × 10^-4 becomes 0.000523 when we move the decimal point 4 places to the left. Therefore, the correct normal decimal notation is option D: 0.000523.
