Answer

To solve the expression \( \frac{999999}{1000} \times 7 \), we will follow these steps:

### Step 1: Understand the expression
We need to evaluate the expression \( \frac{999999}{1000} \times 7 \).

### Step 2: Rewrite the numerator
The numerator \( 999999 \) can be expressed as \( 999 \times 1000 + 999 \). This is because \( 999999 = 999000 + 999 \).

### Step 3: Substitute the rewritten numerator
Now we can rewrite the expression as:
\[ \frac{999000 + 999}{1000} \times 7 \]

### Step 4: Split the fraction
We can separate the fraction:
\[ \left( \frac{999000}{1000} + \frac{999}{1000} \right) \times 7 \]

### Step 5: Simplify each term
Calculating each term:
- \( \frac{999000}{1000} = 999 \)
- \( \frac{999}{1000} = 0.999 \)

So, we have:
\[ (999 + 0.999) \times 7 \]

### Step 6: Add the terms
Now, add \( 999 + 0.999 = 999.999 \).

### Step 7: Multiply by 7
Now, multiply by 7:
\[ 999.999 \times 7 \]

### Step 8: Calculate the final result
Calculating \( 999.999 \times 7 \):
\[ 999.999 \times 7 = 6999.993 \]

### Final Answer
Thus, the value of the expression \( \frac{999999}{1000} \times 7 \) is:
\[ \boxed{6999.993} \]
