Solve Decimal Division: 30.3 ÷ 300 Step by Step

To solve this problem, we will follow these steps:

• Understand the context and arithmetic implication of dividing by $300$.
• Apply the division rule for decimal fractions to manage decimal point movements effectively.
• Verify calculated results with given choices.

Step 1: We know that we need to divide $30.3$ by $300$. To do this, observe that:

Step 2: The number $300$ can be written as $3 \times 100$. When we divide by $300$, it's equivalent to:

• First dividing $30.3$ by $3$.
• Then dividing the result by $100$ (which is moving the decimal point two places to the left).

Step 3: Perform the calculation:
- $30.3 \div 3 = 10.1$.
- Now divide $10.1$ by $100$, which effectively moves the decimal two places left, giving $0.101$.

Therefore, the solution to the problem is $0.101$.
