Solution: Divide every bit of the dividend from the high position, keep the quotient obtained by each calculation, and add the next bit to the remainder for operation. After all the digits of the dividend are operated in this order, the obtained quotients are combined in order, and the remainder is the result of the last operation.

Problem solving process:

Step 1: 3÷2= 1, and the remainder is: 1.

Step 2: 12÷2=6 The remainder is 0.

According to the above calculation steps, the combined result is 16.

Checking calculation: 2× 16=32

Expand data → Check results: first align the last digits of the two multipliers, and then use the second multipliers respectively. Starting from the last digit, each digit is multiplied by one multiplier in turn, and finally the calculation results are accumulated into a product. If the multiplier is decimal, the corresponding multiple can be expanded first, and then the product can be reduced by the corresponding multiple;

Problem solving process:

Step 1: 6×2= 12

Step 2: 1×2=20

According to the above calculation, it adds up to 32.
