D. 221

Explanation

To solve the expression \( 99999 \div 99 \div 9 \), we will follow the order of operations and perform the divisions step by step.

### Step 1: Simplify the Expression
We start with the expression:
\[ 99999 \div 99 \div 9 \]
This can be rewritten as:
\[ (99999 \div 99) \div 9 \]

### Step 2: Divide 99999 by 99
Now, we will first calculate \( 99999 \div 99 \).

To do this, we can use approximation. We know that:
\[ 99 \approx 100 \]
So,
\[ 99999 \div 99 \approx 99999 \div 100 = 999.99 \]
However, we will calculate it exactly:
\[ 99999 \div 99 = 1010.09 \text{ (approximately)} \]

### Step 3: Divide the Result by 9
Next, we take the result from the previous step and divide it by 9:
\[ 1010.09 \div 9 \]
Using approximation again:
\[ 1010.09 \div 9 \approx 112.23 \]

### Step 4: Round the Result
Since we need an approximate answer, we can round \( 112.23 \) to the nearest whole number:
\[ 112.23 \approx 112 \]

### Final Answer
Thus, the final answer to the expression \( 99999 \div 99 \div 9 \) is:
\[ \boxed{112} \]
