Dividing Decimals by Powers of Ten worksheet with 16 practice problems for finding quotients.

To solve the problems involving dividing decimals by powers of ten, we need to understand how moving the decimal point affects the result. Dividing by a power of ten (e.g., 0.1, 0.01, 10, 100) involves shifting the decimal point in the dividend either to the left or to the right.

General Rules:

1. Dividing by a number less than 1 (e.g., 0.1, 0.01):
- Move the decimal point in the dividend to the right by the number of places equal to the number of zeros after the decimal plus one.
- For example, dividing by 0.1 moves the decimal point one place to the right, and dividing by 0.01 moves it two places to the right.

2. Dividing by a number greater than 1 (e.g., 10, 100):
- Move the decimal point in the dividend to the left by the number of zeros in the divisor.
- For example, dividing by 10 moves the decimal point one place to the left, and dividing by 100 moves it two places to the left.

Now, let's solve each problem step by step:

---

Problem 1: \( 883.9 \div 0.1 \)
