(16) $71\div8=$
(17) $73\div8=$
(18) $74\div9=$
(19) $78\div9=$
(20) $80\div8=$

Explanation:

Step1: Calculate exact/quotient-remainder

$63\div7=9$

Step2: Calculate quotient and remainder

$65\div8=8$ remainder $1$ (or $\frac{65}{8}=8.125$)

Step3: Calculate quotient and remainder

$67\div9=7$ remainder $4$ (or $\frac{67}{9}\approx7.44$)

Step4: Calculate quotient and remainder

$68\div7=9$ remainder $5$ (or $\frac{68}{7}\approx9.71$)

Step5: Calculate exact value

$69\div3=23$

Step6: Calculate quotient and remainder

$71\div8=8$ remainder $7$ (or $\frac{71}{8}=8.875$)

Step7: Calculate quotient and remainder

$73\div8=9$ remainder $1$ (or $\frac{73}{8}=9.125$)

Step8: Calculate quotient and remainder

$74\div9=8$ remainder $2$ (or $\frac{74}{9}\approx8.22$)

Step9: Calculate quotient and remainder

$78\div9=8$ remainder $6$ (or $\frac{78}{9}=\frac{26}{3}\approx8.67$)

Step10: Calculate exact value

$80\div8=10$
