Since Milli has $100 to spend on her birthday party and she will pay $40 so the remaining money left for her party is $60. For the $60 left she will then pay $12 for each guest for catering. Divide $60 by $12, the answer is 5. Therefore Milli will have 5 guests for her birthday.

The bus stop method is just like division.
Ex
137÷5=
1.) 5 goes into one zero times so there is a zero on top.
2.) 5 goes into 13 two times, so after the zero there is a 2.
3.) 5 goes into 37 seven times so there is a 7 after the 2.
4.) There is a 2 left and five can't go into school therefore that is a remainder.
