**Objective**: Given a number n and k, Calculate n / k^{2} without using pow() or / operator.

**Example**:

N = 48, k = 4 N/k^{2}= 3

**Approach**: Bit Manipulation

- Right shift the number N by k.
- N = 48
- Bit representation: 0 1 1 0 0 0 0
- Right shift by k = 4
- 0 1 1 which is the representation of 3.

**Java Code**:

**Output**:

Number 48 Divided by 2^4 is: 3
