Welcome to our candy division adventure! Today we're going to learn how to divide two-digit numbers using a fun example. We have 48 delicious candies that need to be shared equally among 4 happy children. Our question is: how many candies will each child receive? Let's find out together using step-by-step division!
Before we start dividing, we need to understand what 48 really means. The number 48 has two digits: 4 in the tens place and 8 in the ones place. This means we have 4 groups of ten candies, plus 8 individual candies. Let's organize our candies this way - we'll make 4 bundles with 10 candies each, and keep 8 candies separate. This organization will help us divide more easily!
Now let's start dividing! First, we divide the tens. We have 4 bundles of ten candies, and we need to share them among 4 children. When we divide 4 by 4, we get 1. This means each child will receive exactly 1 bundle of ten candies. Watch as we give one bundle to each child. Perfect! Now each child has 10 candies from their bundle.
Now for the final step! We still have 8 individual candies to divide among our 4 children. When we divide 8 by 4, we get 2. This means each child will receive 2 more individual candies. Watch as we distribute these candies - 2 candies to each child. Perfect! Now let's count what each child has: 1 bundle of 10 candies plus 2 individual candies equals 12 candies total. So 48 divided by 4 equals 12!
欢迎小朋友们！今天我们要学习两位数除法。假设你有48颗糖果，要平均分给4个好朋友，每个朋友能得到多少颗糖果呢？让我们一起来解决这个有趣的问题！
首先，我们要理解48是由什么组成的。48可以分解为40加8，也就是4个十和8个一。看，这里有4个蓝色的十位块，每个代表10，还有8个红色的小点，每个代表1。这样我们就把48分成了更容易处理的部分。
现在我们开始分配！首先分配十位：40除以4等于10。我们有4个十位块，要分给4个朋友，每个朋友正好得到1个十位块，也就是10。看，每个朋友现在都有10了！
现在分配个位：8除以4等于2。我们有8个小圆点，分给4个朋友，每个朋友得到2个。所以每个朋友总共得到10加2等于12颗糖果！我们成功解决了48除以4的问题！
现在让我们学习正式的长除法写法。我们把4写在除号外面，48写在里面。首先除十位：4除以4等于1，写在上面。然后除个位：8除以4等于2，也写在上面。最终答案是12！这就是长除法的标准步骤。
