Imagine, you are the manager at a movie theater! Sell movie tickets, manage food sales, and help your customers as you practice long division along the way!
Lights, cameras, action!
Popcorn, candy, soda...yum! Kicking back to relax and watch a movie with these treats is the best!
Watch the video below to as you think about eating yummy popcorn at the movie theater!
Cool!
Popcorn at the movies is the best!
Imagine you own a busy movie theater. As the theater manager, you’ve got a lot of responsibilities—keeping your customers happy, making sure there’s plenty of popcorn, and, of course, setting up the theater rooms just right!
Get Started!
Start by setting up the theater rooms.
Your movie theater seats 1,056 people in total. With 8 theater rooms, you need to find out how many seats each room should have to accommodate everyone comfortably.
You can use long division! Long division is a helpful way to split large numbers into smaller, equal groups.
First, set up your long-division problem. Note where the divisor and dividend are placed.
Once your division problem is set up, you can start solving it.
No, move to the following two digits: 10.
1 time.
Multiply: 1 x 8 = 8
Subtract: 10 - 8 = 2
3 times.
Multiply: 3 x 8 = 24
Subtract: 25 - 24 = 1
2 times.
Multiply: 2 x 8 = 16
Subtract: 16 - 16 = 0
Result: 1,056 ÷ 8 = 132
That means there are 132 seats in each theater room. Perfect!
Next Up: Popcorn!
You bought four new popcorn machines, spending a total of $5,280. Now, use long division to determine each machine's cost.
First, set up the problem.
| 4 | $ | 5 | 2 | 8 | 0 |
1 time.
Multiply: 1 x 4 = 4
Subtract: 5 - 4 = 1
| $ | 1 | |||||
| 4 | $ | 5 | 2 | 8 | 0 | |

| 1 |
3 times.
Multiply: 3 x 4 = 12
Subtract: 12 - 12 = 0
| $ | 1 | 3 | ||||
| 4 | $ | 5 | 2 | 8 | 0 | |
| - | 4 | |||||
| 1 | 2 | |||||
| - | 1 | 2 | ||||
| 0 |
2 times.
Multiply: 2 x 4 = 8
Subtract: 8 - 8 = 0
| $ | 1 | 3 | 2 | |||
| 4 | $ | 5 | 2 | 8 | 0 | |
| - | 4 | |||||
| 1 | 2 | |||||
| - | 1 | 2 | ||||
| 0 | 8 | |||||
| - | 8 | |||||
| 0 |
0 times.
Multiply: 0 x 4 = 0
Subtract: 0 - 0 = 0
| $ | 1 | 3 | 2 | 0 | ||
| 4 | $ | 5 | 2 | 8 | 0 | |
| - | 4 | |||||
| 1 | 2 | |||||
| - | 1 | 2 | ||||
| 0 | 8 | |||||
| - | 8 | |||||
| 0 | 0 | |||||
| - | 0 | |||||
| 0 |
Result: $5,280 ÷ 4 = $1,320
Each popcorn machine costs $1,320. Not a bad deal for all that delicious popcorn you’ll be serving!
Keep It Up!
Continue practicing long division while you watch the following video. Try to follow along with paper and pencil.
Great work!
Back to The Theater
Now, check on the soda machines.
Your theater has two soda machines, and together they cost $6,426.
Set up and solve this long-division problem: 6,426 ÷ 2.
When you’re ready, check your answer against the one below.
Fantastic job!
Now you’re ready for more long-division practice!
Head to the Got It? section to keep up the great work and master these skills. You’re well on your way to being a division pro!
