### Step-by-Step Solution:

1. **Identify the expression**:
\[ 236.05 - 316.87 + 238.85 \]

2. **Perform the addition first**:
We will add \( 236.05 \) and \( 238.85 \) together.
\[ 236.05 + 238.85 \]

3. **Calculate the addition**:
- Align the numbers by their decimal points:
```
236.05
+ 238.85
---------
```
- Start adding from the right:
- \( 5 + 5 = 10 \) (write down 0 and carry over 1)
- \( 0 + 8 + 1 = 9 \) (no carry)
- \( 6 + 3 = 9 \) (no carry)
- \( 2 + 2 = 4 \) (no carry)
- The result of the addition is:
\[ 474.90 \]

4. **Subtract \( 316.87 \) from \( 474.90 \)**:
\[ 474.90 - 316.87 \]

5. **Calculate the subtraction**:
- Align the numbers by their decimal points:
```
474.90
- 316.87
---------
```
- Start subtracting from the right:
- \( 0 - 7 \) (we need to borrow, making it \( 10 - 7 = 3 \))
- \( 8 - 8 = 0 \) (no borrow)
- \( 4 - 6 \) (we need to borrow, making it \( 14 - 6 = 8 \))
- \( 3 - 3 = 0 \) (no borrow)
- The result of the subtraction is:
\[ 158.03 \]

6. **Final answer**:
\[ 236.05 - 316.87 + 238.85 = 158.03 \]
