$6.626 \times {10}^{ - 34} \times 3 \times {10}^{8} \div 700 \times {10}^{ - 9} \\ = \frac{6.26 \times 3 \times {10}^{ - 34 + 8} }{700 \times {10}^{ - 9} } \\ = \frac{626 \times {10}^{ - 2} \times 3 \times {10}^{ - 26} }{7 \times {10}^{2} \times {10}^{ - 9} } \\ = \frac{626 \times 3 \times {10}^{ - 2 - 26 - 2 + 9} }{7} \\ = \frac{1878 \times {10}^{ - 21} }{7} \\ = 268.29 \times {10}^{ - 21} \\ = 2.6829 \times {10}^{2} \times {10}^{ - 21} \\ = 2.6829 \times {10}^{ - 19}$
