8. \( 3007 \div 521 \)

To approach the division \( 3007 \div 521 \) more effectively, remember that estimating can simplify calculations. First, round \( 521 \) to \( 500 \). Dividing \( 3000 \) (near \( 3007 \)) by \( 500 \) gives an estimate of around \( 6 \). This tells you the actual quotient will likely be between \( 6 \) and \( 7 \). When computing \( 3007 \div 521 \) exactly, perform long division. \( 521 \) goes into \( 3007 \) five times, which totals \( 2605 \). Subtract and bring down the next digit to get a remainder of \( 402 \). Dividing \( 402 \) by \( 521 \) isn't possible, so the quotient is \( 5 \) with a remainder, or expressed as a decimal, about \( 5.77 \).
