When writing vertical marks, write vertical marks first; Then write the dividend and divisor on the inside and left of the divisor respectively; Quotient is written on the divisor and aligned with the unit of the dividend; Finally, write the product of quotient and divisor under the dividend (aligned with the same number of digits).

Calculation steps of vertical segmentation

Step 1/4

When calculating the division vertically, start from the most significant bit of the dividend. If it can't be divided, divide it by combining the highest bit with the next bit until the dividend can be divided.

Step 2/4

Vertical division calculation process, such as: 42 divided by 7 [from high to low], 42 divided by the first ten digits 4; If 4 is not divisible by 7, then use the highest bit and the next bit to synthesize a number to be divisible until the dividend can be divisible; If 4 can't be divided by 7 in the division of 7, combine 4 and 2 into a number. If 42 is divided by 7, the quotient is 6.

Step 3/4

When calculating division vertically, the number of digits should be aligned in the process of column verticality, starting with the highest digit.

Step 4/4

Take 75 divided by 5 columns as an example. First, the highest dividend, that is, the tenth 7, is divided by 5, and the quotient is 1. The remainder is 2, and then the quotient is 5, so the final result of the vertical form is 15.
