When the little sloppy calculated the division calculation problem, he wrote the dividend 66.6 as 6.66 by mistake. The resulting quotient was 19.98 less than the correct quotient. What is the correct quotient?
小马虎在计算除法计算题时，把被除数66.6错写成6.66，结果所得的商比正确的商少19.98，正确的商是多少．
<gadget id="calculator">1 / 10</gadget>
<output>1/10 = around 0.1</output>

<gadget id="calculator">1 - (1/10)</gadget>
<output>9/10 = around 0.9</output>

<gadget id="calculator">19.98 / (9/10)</gadget>
<output>22.2</output>

<result>22.2</result>
