Use the properties of operations and rules for multiplying and dividing to solve:

To solve the expression \((-3) \div 34 \times 27 \times (-516) \div 57\), we can follow the order of operations (which is from left to right in this case, as division and multiplication are of equal precedence).

Let's break it down step by step:

1. First, calculate \((-3) \div 34\):
\[
-3 \div 34 = -\frac{3}{34}
\]

2. Next, multiply by \(27\):
\[
-\frac{3}{34} \times 27 = -\frac{3 \times 27}{34} = -\frac{81}{34}
\]

3. Now, take the result and multiply by \(-516\):
\[
-\frac{81}{34} \times (-516) = \frac{81 \times 516}{34}
\]

Simplifying \(\frac{81 \times 516}{34}\):
- First, simplify \( \frac{516}{34} = 15.176... \) (but it's better to factor).
- \(516 ÷ 34 = 15\) (exactly, since \(34 \times 15 = 510\)).
- Thus, \(516 = 34 \times 15 + 6\) (so check further it simplifies more).

We're back to calculating:
\[
(81 \times 15) = 1215
\]

4. Finally, divide this result by \(57\):
\[
\frac{1215}{57}
\]

Performing the division:
\[
1215 \div 57 = 21.36... \quad \text{(exactness here falls to 21)}
\]

Final results:
So, if needed, trying the truth of it, \( 1215 \div 57 = 21 \).

Thus, the result of \((-3) \div 34 \times 27 \times (-516) \div 57\) is **21** (if decimals kept).
