Division with remainder is a simple integer division method, which can be used to judge whether an integer can be divisible by another integer and calculate the remainder. The following are the advantages and disadvantages of division with remainder:

Advantages:

1. Easy to understand: Division with remainder is a very simple method, suitable for primary school students to learn. It doesn't need to use complex algorithms, but only needs to do some simple mathematical operations to get the answer.

2. Save time: Compared with other complicated algorithms, division with remainder requires less calculation and can save calculation time. Especially in the study of primary school students, it can help them understand and master mathematics knowledge faster.

3. Help to understand mathematical concepts: Division with remainder can help students better understand mathematical concepts. Through practical operation, students have a deeper understanding of the relationship among integer, division, quotient and remainder.

Disadvantages:

1. Limited scope of application: division with remainder is only applicable to integer division operation, and cannot be used for other types of mathematical operations. For example, the division of fractions requires other algorithms.

2. Not accurate enough: the quotient and remainder obtained by remainder division are not necessarily the most accurate results, because it is only a simple estimation method. When more accurate calculation is needed, other algorithms need to be used.

3. Error-prone: If students do not master the calculation method of division with remainder, it is easy to make calculation errors, especially when calculating large numbers. Therefore, it is necessary to guide students to master the correct calculation method and avoid mistakes in teaching.
