(11) $68\div8=$
(12) $68\div9=$
(13) $69\div3=$
(14) $69\div7=$
(15) $69\div8=$
(16) $69\div9=$
(17) $70\div7=$
(18) $70\div8=$
(19) $70\div9=$
(20) $70\div10=$

Explanation:

Step1: Calculate quotient and remainder

$68\div8 = 8$ remainder $4$, or $\frac{68}{8}=8.5$

Step2: Calculate quotient and remainder

$68\div9 = 7$ remainder $5$, or $\frac{68}{9}\approx7.56$

Step3: Divide evenly

$69\div3 = 23$

Step4: Calculate quotient and remainder

$69\div7 = 9$ remainder $6$, or $\frac{69}{7}\approx9.86$

Step5: Calculate quotient and remainder

$69\div8 = 8$ remainder $5$, or $\frac{69}{8}=8.625$

Step6: Calculate quotient and remainder

$69\div9 = 7$ remainder $6$, or $\frac{69}{9}\approx7.67$

Step7: Divide evenly

$70\div7 = 10$

Step8: Calculate quotient and remainder

$70\div8 = 8$ remainder $6$, or $\frac{70}{8}=8.75$

Step9: Calculate quotient and remainder

$70\div9 = 7$ remainder $7$, or $\frac{70}{9}\approx7.78$

Step10: Divide evenly

$70\div10 = 7$
