You are in charge of all the sprinkles in a cupcake factory. How do you make sure they all get the same amount? Long Division! Explore how long division ensures the deliciousness of every bite.
Welcome to the world of cupcakes! As the new Director of Sprinkles at the cupcake factory, you have a super fun mission: to sprinkle just the right amount of colorful sprinkles on every delicious cupcake.
But hold on! You’ve got a big challenge ahead.
Get ready to dive into the exciting world of long division! Learn how to master the division of big numbers—like 5-digit dividends and 3-digit divisors—so you can sprinkle joy all over your treats and become the best Sprinkler the factory has ever seen!
Cupcakes are amazing, but the sprinkles on a cupcake take them to a whole new level! As the Sprinkle Director, your job is to ensure each cupcake gets just the right amount of sprinkles.
To do this, you must divide the total number of sprinkles in the factory by the number of cupcakes you make. This way, every cupcake will look and taste fantastic!
You have 24,576 sprinkles ready and must make 512 cupcakes for an order.
Setting Up the Problem
Start with 24,576 divided by 512. Set it up like this.
Now, before diving in, take a look at the dividend of 24,576.
Nope! But if you look at 2,457, you can start estimating.
Estimating and Multiplying
The first thing to do is estimate and multiply.
512 is close to 500.
2,457 is close to 2,500.
Try 512 x 5.
Yep! It is 2,560.
That’s too much! Try 512 x 4 instead.
You're right! It is 2,048.
Now, write 4 on top and 2,048 underneath.
Time to Subtract
Now, subtract 2,457 - 2,048.
That's right! It's 409.
Bring down the 6 to make 4,096.
Repeating the Process
Now, think about how many times 512 can fit into 4,096, and estimate again.
512 is close to 500.
4,096 is close to 4,000.
Try 512 x 8.
You got it! It’s 4,096!
Write 8 on top and subtract.
Nope! Because 4,096 - 4,096 = 0.
How Many Sprinkles on Each Cupcake?
Yes! 48 sprinkles. Delicious!
Try Another Example!
Divide 10,208 by 176.
Set up the problem like this.
Nope!
Start estimating.
176 is close to 200.
1,020 is close to 1,000.
Start with 176 x 5.
Yes! It’s 880
Now, write 5 on the line above and 880 underneath. It’s time to subtract.
That’s 140! Bring down the 8 to make 1,408.
You got it! 8 times. Write up on top and subtract.
That’s right! It’s 0, so no remainder!
