검증된 단계별 안내
1
Identify the operation: The problem requires division of two numbers, specifically dividing 44.4788 by 5.27.
Set up the division expression as a fraction: \(\frac{44.4788}{5.27}\).
To simplify the division, eliminate the decimal in the divisor by multiplying both numerator and denominator by 100 (since 5.27 has two decimal places). This gives \(\frac{44.4788 \times 100}{5.27 \times 100} = \frac{4447.88}{527}\).
Now, perform the division of 4447.88 by 527 using long division or a calculator to find the quotient.
Express the quotient as the final answer, which represents the result of the original division problem.
