Write a Python function `division_elements` that takes in two tuples of numbers and performs element-wise division across the given tuples. The function should return a new tuple containing the results of the division for each corresponding pair of elements.
#### Requirements:
- The function should handle tuples of the same length.
- Perform integer division (`//`) for each pair of elements.
- Assume that the second tuple will not contain zeroes.
#### Example Usage:
```python [main.nopy]
result = division_elements((10, 4, 6, 9), (5, 2, 3, 3))
print(result) # Output: (2, 2, 2, 3)
result = division_elements((12, 6, 8, 16), (6, 3, 4, 4))
print(result) # Output: (2, 2, 2, 4)
result = division_elements((20, 14, 36, 18), (5, 7, 6, 9))
print(result) # Output: (4, 2, 6, 2)
```
#### Constraints:
- Both input tuples will have the same length.
- The second tuple will not contain zeroes.
