### Problem Analysis in Python

In this section, we will delve into solving a given algorithmic problem using Python. Below is the description and steps of the problem provided. Your task will be to implement and experiment with this algorithm by testing it with various numerical values for `a` and `d` to discern its functionality and purpose.

#### Algorithm Description

```
Use Python as appropriate to help solve the following problem.

Try various numerical values of a and d to determine what this algorithm does. Explain its purpose.

START
    Get the values of a and d
    Set the value of r to a
    Set the value of q to 0
    While r is greater than or equal to d
        Set the value of r to r - d
        Increase the value of q by 1
    Output q
    Output r
END
```

#### Steps of the Algorithm

1. **Input Acquisition:**
   - Obtain two numerical values, `a` and `d`.

2. **Initialization:**
   - Assign the value of `a` to a variable `r`.
   - Set the value of another variable `q` to 0.

3. **Iteration and Calculation:**
   - Continue executing the loop as long as `r` is greater than or equal to `d`.
     - Within the loop:
       - Subtract `d` from `r` and update `r` with the result.
       - Increment the value of `q` by 1.

4. **Output:**
   - Print the values of `q` and `r`.

The described algorithm essentially performs a repetitive subtraction of `d` from `a`, counting the number of times this subtraction can occur while `r` remains non-negative. At the end of this process:

- `q` represents how many times `d` was subtracted from `a`.
- `r` represents the remainder left when `a` is divided by `d`.

In mathematical terms, this algorithm computes the quotient and the remainder of the division of `a` by `d` through iterative subtraction.

#### Practical Implementation with Python

Here's how you might implement this algorithm in Python code:

```python
# Get user input for a and d
a = int(input("Enter value of a: "))
d = int(input("Enter value of d: "))

# Initialize r and q
r = a
q = 0

# Perform iterative
