To solve the given mathematical expression:

\[
\frac{4^3 \cdot (7^2)^3}{(-3)^5} \div \left( \frac{(-4)^2 \cdot 7^5}{36} \right)
\]

We'll break down the operations step-by-step:

### Step 1: Evaluate Powers and Squares
1. \(4^3 = 64\)
2. \(7^2 = 49\) and \((7^2)^3 = 49^3 = 117649\)
3. \((-3)^5 = -243\)
4. \((-4)^2 = 16\)

### Step 2: Substitute and Simplify
- Replace the values in the expression:
\[
\frac{64 \cdot 117649}{-243} \div \left( \frac{16 \cdot 16807}{36} \right)
\]

### Step 3: Calculate the Numerators
1. \(64 \cdot 117649 = 7529536\)
2. \(16 \cdot 16807 = 268912\)

### Step 4: Solve Each Fraction
1. \(\frac{7529536}{-243} = -30989\) (rounded to nearest integer)
2. \(\frac{268912}{36} = 7472\)

### Step 5: Divide the Results
\[
\frac{-30989}{7472} \approx -4.148
\]

The result of the expression is approximately \(-4.148\).
