Solve the Division Problem: 200:1 Basic Arithmetic Challenge

To solve this problem, we'll follow this logical reasoning:

• Step 1: Identify the operation - We are asked to find the result of dividing $200$ by $1$.

• Step 2: Apply the division rule - According to arithmetic rules, any number divided by $1$ will result in the number itself. Thus, $200 \div 1 = 200$.

Therefore, the solution to the problem is $\mathbf{200}$, which corresponds to choice 3.
