Step-by-step solution

First, we break down 122 into smaller numbers and write the division exercise in the form of a fraction:

(100+20+2)×124= (100+20+2)\times\frac{12}{4}=

We solve the fraction exercise:

(100+20+2)×3= (100+20+2)\times3=

We then multiply the terms inside the parentheses by 3 and obtain the following result:

(100×3)+(20×3)+(2×3)= (100\times3)+(20\times3)+(2\times3)=

Lastly we solve each of the exercises inside of the parentheses:

300+60+6=366 300+60+6=366
