You can identify that:
1. The Dividend is:
2. The Divisor is:
Then, you can set up the following:
The steps are:
1. Choose the first two digits of the dividend (30). Find a number that when you multiply it by the dividend (12) gives you 30 or a number whose value is closer to 30. This would be 2.
2. Write the number 2 in the Quotient section.
3. Multply the divisor by 2 and write the product below the number 30.
4. Subtract them.
Then:
5. Bring down the next digit of the divided (4).
6. Find a number that when you multiply it by the dividend gives you 64 or a number whose value is closer to it. This would be 5.
7. Write 5 in the Quotient section.
8. Multiply the divisor by 5 and write the product below 64.
9. Subtract them.
Use this procedure will all the digits. Remember that when you bring down the digit 8, since it is the first number after the decimal point, you must write the decimal point after the numer 5 in the quotient section.
Then the answer is:
