We can use a circle to represent the number 48. In this circle, we can regard each small part as the number 1, thus forming a complete circle with 48 small parts.

We need to divide the circle into four equal parts. This can be achieved by marking four points on the edge of the circle and connecting these points. In this way, we get four equal sectors, each sector represents the number 12 (that is, the result of dividing 48 by 4).

We need to use graphics to represent these four parts. One way is to use four small circles, each representing a number 3 (because 12 is made up of four 3s). We can put these four small circles in four sectors, and each small circle represents a part of the sector.

Another method is to use a straight line to represent each sector. We can divide this straight line into four equal parts, each representing the number 3. Then, we can use graphics to represent these four parts, such as four small triangles or four small rectangles.

No matter which method we choose, the final figure should clearly show the meaning of "48 divided by 4 circles 1 circle". The diagram may look like this:

In a circle, we can see four sectors, and each sector consists of some small circles or straight lines. Each small circle or straight line segment represents the number 3, and the whole graph represents the result of dividing the number 48 by 4, that is, the number 12.

Characteristics of division of labor:

1, divisible: in the division operation, when the dividend can be divisible by the dividend, the quotient obtained is an integer and the remainder is 0. This feature shows that the result of division operation can be integer or rational number. For example, the quotient of 10 divided by 3 is 3, and the remainder is 1, because 10 can be divisible by 3, the quotient is 3, and the remainder is 0.

2. Uniqueness: In the division operation, the quotient and the remainder are unique. This means that when two numbers are divided, their quotient and remainder are fixed and unique. This feature ensures the uniqueness and certainty of the division result. For example, in the operation of dividing 9 by 3, the quotient is 3 and the remainder is 0, and any other numerical value does not conform to the definition and operation rules of division.

3. Order: In the division operation, the order of the results is meaningful. This shows that when one number is divided by another, the quotient and remainder obtained are continuous. This feature makes the result of division logical and interpretable. For example, if we divide 10 by 3, the first thing we get is quotient 3 and the remainder 1, which means that we can divide 10 into three parts, each of which is 3, and the remainder is 1.
