To find the number of opening parentheses `(` in the given string, we must count every occurrence of `(` within it. Here's how you count them manually:

1. Go through each character in the string.
2. Each time you encounter the character `(`, you count it.

Let's go through the string:

`()((()(()((()()((()))()((()(()(((()((()())))()(())()))())()(())((()()((()(()((()()((()))()((()(()(((()((()())))()(())()))())()(())((()))()(((()((()((()()((()))()((()(()(((()((()())))()(())()))())()(())(((()((()())))()(())()))())()(()))()(((()((()((()()((()))()((()(()(((()((()())))()((()((()(()((()()((()))()((()(()(((()((()())))()(())()))())()(())((()))()(((()((()((()()((()))()((()(()(((()((()())))()(())()))())()(())(((()((()())))()(())()))())()(()))()))())()(())(((()((()())))()(())()))())()(()`

**Counting the `(` characters from the string:**

- The total number of opening parentheses `(` is **164**.

Manual counting might be prone to errors due to the large size and complexity of the string. A programmatic approach (using a scripting or programming language) would provide a more accurate and easier count.
