Missing Digits Division
1. **Stating the problem:** We have a division problem with missing digits represented by squares (□). The divisor is $1\,\square\,\square$, the dividend is $8\,\square\,2 . 9\,\square\,\square$, and the quotient ends with $3$. We need to find the missing digits.
2. **Understanding the division setup:** The division is of the form:
$$\frac{8\,\square\,2 . 9\,\square\,\square}{1\,\square\,\square} = \text{quotient ending with } 3$$
3. **Key observations:**
- The divisor is a three-digit number starting with 1.
- The dividend is a number with digits and decimals.
- The quotient ends with digit 3.
4. **Approach:**
- Let the divisor be $D = 1ab$ where $a,b$ are digits.
- Let the dividend be $N = 8c2.9de$ where $c,d,e$ are digits.
- The quotient $Q$ satisfies $Q = \frac{N}{D}$ and ends with digit 3.
5. **Constraints and reasoning:**
- Since the divisor starts with 1, $D$ is between 100 and 199.
- The dividend starts with 8, so $N$ is about 8000+ (considering decimal places).
- The quotient $Q$ is approximately $\frac{N}{D}$.
6. **Trial and error or algebraic approach:**
- Since the problem is incomplete without more data, we cannot determine exact digits.
7. **Conclusion:**
- More information or context is needed to solve for the missing digits.
**Final answer:** Cannot determine missing digits with given information.
