Step 1: Write 5 10÷65 into the vertical score. As shown in the figure:

Step 2: Look at the highest digit of dividend first. Since the dividend is 2 digits, let's look at the 2 digits with the highest dividend, that is, 5 1. But because 5 1 < 65, we need to look at the next digit of the dividend, which is 5 10. As shown in the figure:

Step 3: Calculate the maximum quotient of 5 10÷65. The result is 7. Where the divisor is divided, the quotient is written on it. As shown in the figure:

Step 4: Calculate 7×65, and the result is 455. Write vertically. As shown in the figure:

Step 5: Calculate the remainder, 5 10-455=55. Write it in vertical form and complete this calculation. The result is 5 10 ÷ 65 = 7.55. As shown in the figure:

Vertical calculation

There are two main points in the calculation of column vertical pen: the same digit alignment, starting from the unit. You can add ten digits first without carrying, but it is not recommended for carrying addition later. The format of exercise books is strictly in accordance with the following requirements:

1, the horizontal formula is written from the left end of the horizontal grid line in the math book.

2. The first addend in vertical form is written under the second addend in horizontal form, and the plus sign is aligned with the plus sign in horizontal form. The same numbers of addend, addend and sum must be aligned.

3. After calculating the vertical columns, don't miss the horizontal numbers.
