```

### Step 2: Subtract the first two numbers
Now, we will subtract \( 56.84 \) from \( 213.4 \). To do this, we can convert \( 213.4 \) to \( 213.400 \) for easier subtraction.

```
213.400

```

### Step 3: Subtract the next number
Next, we will subtract \( 11.87 \) from \( 156.56 \). Again, we can write \( 156.56 \) as \( 156.560 \).

```
156.560
- 11.870
-----------
144.690
```

### Step 4: Subtract the last number
Finally, we will subtract \( 16.087 \) from \( 144.69 \). We can write \( 144.69 \) as \( 144.690 \) for easier subtraction.

```
144.690
- 16.087
-----------
128.603
```

### Final Answer
The simplified result of \( 213.4 - 56.84 - 11.87 - 16.087 \) is \( 128.603 \).
