To divide 72 by 4.5 manually, follow these steps:

1. **Remove the decimal**: To simplify the division, multiply both the dividend (72) and the divisor (4.5) by 10 to eliminate the decimal in the divisor. This gives:
   \[
   \frac{72 \times 10}{4.5 \times 10} = \frac{720}{45}
   \]

2. **Perform the division**: Now divide 720 by 45:
   \[
   720 \div 45 = 16
   \]

So, \( 72 \div 4.5 = 16 \).
