A divider is the division of decimals. First, move the decimal point of (divisor) to become (integer). Such as 0.756 ÷ 0.18 = 75.6 ÷18 = 4.2.
The decimal point of the divisor is moved several digits to the right, and the decimal point of the dividend is also moved (several digits) (there are not enough digits, so "0" is used at the end of the dividend); Then it is calculated by fractional division with divisor (integer). 3.3÷0.75=330÷75=4.4。
When dividing by integer, the decimal point of quotient should be aligned with the decimal point of dividend. In the division formula, where is the quotient written except the dividend, that is to say, the dividend is aligned with the same digit of the quotient, and the same digit is aligned only when the decimal point is aligned, so the decimal point of the quotient should be aligned with the decimal point of the dividend.

Mathematics [English: Mathematics, from ancient Greece μ? θξμα(máthēma)； Often abbreviated as math or maths], it is a discipline that studies concepts such as quantity, structure, change, space and information.
Mathematics is a universal means for human beings to strictly describe and deduce the abstract structure and mode of things, and can be applied to any problem in the real world. All mathematical objects are artificially defined in essence. In this sense, mathematics belongs to formal science, not natural science. Different mathematicians and philosophers have a series of views on the exact scope and definition of mathematics.
Mathematics plays an irreplaceable role in the development of human history and social life, and it is also an indispensable basic tool for studying and studying modern science and technology.
Mathematics (hanyu pinyin: shùXué；; ; Greek: μ α θ η μ α κ; English: mathematics or maths), whose English comes from the ancient Greek word μθξμα(máthēma), has the meaning of learning, learning and science. Ancient Greek scholars regarded it as the starting point of philosophy and the "foundation of learning". In addition, there is a narrow and technical meaning-"mathematical research".
