What value can you multiply the divisor and dividend by to begin dividing this problem? 93÷0.007

You want to avoid with dividing decimals so you will need to move the decimal place by multiplying by 10s. Every time you move a decimal point to the right, you are multiplying by 10. 

So...

93 / 0.007
(93 x 1000)/(0.007 x 1000)    ← multiply the dividend and divisor by 1000 
                                                   since you are moving the decimal point 3                                                        times to the right (10 x 3)
93000/7

Now you don't any decimal points to worry about. Hope i helped.. ^^
