Explain how you can use estimation to place the decimal point in the quotient 42.56 divided by 22

Well you already know how many times 22 can go into 42, it's 1. 42 - 22 is 20, drag down the 5 now it's 205. then ask yourself how many times can 22 go into 205, i would be 9. 9 x 22 = 198, drag down the 6 = 1986. then 22 can go into 1986, 9 times so the answer would be 1.93 rounded to 1.9 

I KNOW THIS IS NOT ESTIMATION BUT HOPE IT HELPS

< i think this is the answer unless i did my math wrong
