1, where every two digits from the left are a paragraph. If there is a decimal point, every two digits from the right of the decimal point are used to separate the parts.
2. Find the complete square number not greater than the first number on the left, which is the "quotient";
3. Subtract the quotient from the first part on the left and write their difference in the second part on the right as the first remainder;
4. Multiply the quotient by 20 and try to divide it by the first remainder to get the largest integer as the trial quotient (if this largest integer is greater than or equal to 10, use 9 or 8 as the trial quotient);
5. Multiply the quotient by 20, add the trial quotient, and then multiply the trial quotient. If the product is less than or equal to the remainder, the trial quotient is written after the quotient as a new quotient; If the obtained product is greater than the remainder, try again by reducing the trial quotient until the product is less than or equal to the remainder;
6. In the same way, continue to ask.

Learning mathematics plays an important role in personal development and comprehensive quality. Let me introduce the benefits of learning mathematics in detail.
1. Cultivate logical thinking: Mathematics is a subject that requires strict logic and reasoning ability. By studying mathematics, we can cultivate our logical thinking ability and improve our ability to analyze and solve problems. Mathematics teaches us how to conduct rigorous reasoning and argumentation, and cultivates the rigor of our thinking.
2. Develop abstract thinking: Mathematics is a highly abstract subject, and learning mathematics can enable us to exercise the ability of abstract thinking. Through mathematical symbols, formulas and models, learn abstract concrete problems and solve them by mathematical methods. This kind of abstract thinking ability is of great significance for solving practical problems and learning other disciplines.
3. Cultivate problem-solving ability: Mathematics is a practical subject, which provides a set of problem-solving methods and ways of thinking. Learning mathematics can cultivate our problem-solving ability, let us learn to analyze problems, put forward assumptions, look for evidence, deduce and verify conclusions, and improve our comprehensive quality and ability to solve practical problems.
To sum up, learning mathematics can cultivate logical thinking and abstract thinking ability, develop problem-solving ability and mathematical thinking, enhance spatial imagination and the supporting role of basic disciplines, cultivate patience and meticulousness, enhance teamwork awareness, enhance computing ability and mathematical literacy, provide more life opportunities and increase employment competitiveness.
