Four digits divided by two digits is calculated as follows:

1, solve step by step from dividend left to right.

2. If the two digits on the left are divisible, divide by two digits. If it is not divisible, divide the divisor by the left 3 digits of the dividend.

3. If the dividend of 4 digits is divisible, it is completed. If not, you can write in the form of remainder or add zero to continue the right operation according to the requirements of the topic, and keep the decimal places.

Notes on vertical writing of division;

1, write the divisor. Note that the apostrophe on the left is not too long, just wrap the dividend, and the horizontal line on it is not too long or too short, just a little longer than the dividend.

The dividend should be written in the divisor.

The divisor should be written in the divisor.

4. When writing quotient, pay attention to writing quotient on divisible digits.

5. Write the product of the divisor and quotient under the dividend, and the digits should be aligned.

6. Write the remainder, draw a horizontal line first and then write the remainder. The horizontal line drawn is as long as the horizontal line divided by the symbol.
