The problem asks to find the quotient of $0.2430 \div 0.6$, and to write the answer as a decimal.

Step-by-step solution:

1. Rewrite the division: $0.2430 \div 0.6$

2. Remove the decimals by multiplying both numbers by 10 to eliminate the decimal point in the divisor: $\frac{0.2430 \times 10}{0.6 \times 10} = \frac{2.430}{6}$

3. Perform the division: $2.430 \div 6 = 0.405$

Thus, the quotient is: $\boxed{0.405}$
