How does 0.42 divide by 0.35 equal 1.2?

When you're dividing decimals, you have to move the decimal on the number on the outside to make it a whole number. You have to move both decimals the same amount of times. Then you simply divide. You should get 7 left over, so add a decimal and 0 to 42 and bring down the zero all the way to 70. 35 x 2= 70. You should get 1.2. I hope this helped!!
