We can make an estimate for the given division by rounding the dividend to the nearest hundred and the divisor to the nearest ten.
We obtain:
[tex]812\div17\cong800\div20=40[/tex]
Now, using partial-quotients division, we obtain:
17 ) 812
-170 +10 because 10*17=170
642
-170 +10
472
-170 +10
302
-170 +10
132
