To simplify the expression \((2 + 4 \div 8 + 10) - 7(2 + 4 \div 8 + 10)\), we first simplify the expression inside the parentheses.
1. Calculate \(4 \div 8\):
\[
4 \div 8 = 0.5
\]
2. Substitute this back into the expression:
\[
2 + 0.5 + 10
\]
3. Calculate \(2 + 0.5 + 10\):
\[
2 + 0.5 = 2.5
\]
\[
2.5 + 10 = 12.5
\]
Now we substitute \(12.5\) back into the original expression:
\[
(12.5) - 7(12.5)
\]
Next, calculate \(7(12.5)\):
\[
7 \times 12.5 = 87.5
\]
Now, substitute this into the expression:
\[
12.5 - 87.5
\]
Finally, calculate:
\[
12.5 - 87.5 = -75
\]
Thus, the simplified expression is:
\[
\boxed{-75}
\]
