1. The problem is to simplify the expression $\frac{1421}{5}$. 2. The formula for division is $\text{Dividend} \div \text{Divisor} = \text{Quotient}$. 3. Divide 1421 by 5: $$1421 \div 5 = 284.2$$ 4. This means 5 goes into 1421 exactly 284 times with a remainder of 1, or as a decimal, 284.2. 5. Therefore, the simplified result of $\frac{1421}{5}$ is $284.2$.
