To divide \( 86\sqrt{2} \), we first need to clarify what you want to divide it by. However, if you simply want to simplify or further break down \( 86\sqrt{2} \), it is already in a simplified form as a product of a constant and a square root.
If you meant to divide \( 86\sqrt{2} \) by a number (for example, dividing by 2 or any other number), please specify that number, and I can assist you with the division.
If none of that applies and you're asking whether \( 86\sqrt{2} \) can be simplified further in itself or not, the answer is:
"This expression is already simplified and cannot be divided further."
