To perform long division of \( 19.2 \) by \( 4 \), follow these steps:
1. **Set up the division**: Write it as \( 4 \) going into \( 19.2 \).
2. **Ignore the decimal**: First, consider \( 192 \) instead of \( 19.2 \). We’ll place the decimal point in the quotient later.
3. **Divide \( 19 \) by \( 4 \)**:
- \( 4 \) goes into \( 19 \) a total of \( 4 \) times since \( 4 \times 4 = 16 \).
- Write \( 4 \) above the line.
4. **Subtract**:
- \( 19 - 16 = 3 \).
5. **Bring down the next digit**: Bring down the \( 2 \) from \( 192 \), making it \( 32 \).
6. **Divide \( 32 \) by \( 4 \)**:
- \( 4 \) goes into \( 32 \) exactly \( 8 \) times since \( 4 \times 8 = 32 \).
- Write \( 8 \) above the line next to \( 4 \).
7. **Subtract again**:
- \( 32 - 32 = 0 \).
Now, since we initially multiplied by \( 10 \) (because we moved the decimal once to the left), place the decimal point in the quotient:
- The final result of the division \( 19.2 \div 4 \) is \( 4.8 \).
Thus,
\[
19.2 \div 4 = 4.8
\]
