How Does SafeMath Handle Division by Zero?

SafeMath handles division by zero by explicitly including a check before the division operation. If the denominator is zero, the SafeMath function will use a require statement to revert the transaction, preventing the division-by-zero error.

While the EVM itself would revert a division by zero, the explicit check ensures a cleaner error message and is part of the library's philosophy of ensuring all arithmetic operations are safe and predictable.
