Let's solve each of these decimal division problems step by step. The goal is to find the
quotient (the result of dividing one number by another), and in this case, all answers should be
whole numbers.

🔍 Strategy:
When dividing decimals, we can make the divisor (the number we're dividing by) a whole number by
multiplying both the dividend and divisor by the same power of 10. This does not change the value of the quotient.
Alternatively, you can use long division with decimals.
Let’s go through each problem:
