Solve the Division Problem: Computing 99:99

To solve this problem, we'll follow these steps:

• Step 1: Identify the given operation, which is $99 \div 99$.
• Step 2: Utilize the properties of division, specifically that a number divided by itself equals 1, provided the number is not zero.
• Step 3: Apply this property to the given numbers.

Now, let's work through the solution:
Step 1: We have the division operation $99 \div 99$.
Step 2: According to division properties, if a non-zero number is divided by itself, it results in 1. This is because the operation effectively counts how many times the divisor fits into the dividend, which in this case, is exactly once.
Step 3: Applying this understanding, $99 \div 99 = 1$.

Therefore, the solution to the problem is $1$.
