how do you use long division to do 0.18 divided by 0.3

The easiest way is to get rid of the decimals before you start: multiply both numbers by 100 before you divide one into the other. If you do that, you'll end up with 18 divided by 30, which is a FAR easier long division sum to tackle.

To use long division to divide 0.18 by 0.3, follow these steps:

Step 1: Write the dividend and divisor in the correct positions. In this case, we have 0.18 as the dividend (the number to be divided) and 0.3 as the divisor (the number we are dividing by). Write them down like this:

___________
0.3 | 0.18

Step 2: Determine the first digit of the quotient. Look at the leftmost digit of the dividend (0.18) and divide it by the divisor (0.3). In this case, 0.18 divided by 0.3 is less than 1, so the quotient will be less than 1. Write down 0 as the first digit of the quotient above the line:

___________
0.3 | 0.18
0

Step 3: Multiply the divisor (0.3) by the first digit of the quotient (0). Write the result below the line, aligned with the dividend:

___________
0.3 | 0.18
0.00

Step 4: Subtract the result obtained in the previous step from the dividend. Write the difference below the line:

___________
0.3 | 0.18
- 0.00
________
0.18

Step 5: Bring down the next digit of the dividend. In this case, there are no digits left after the decimal point, so you can bring down a 0:

___________
0.3 | 0.18
- 0.00
________
0.18
0

Step 6: Since there are no more digits to bring down, we have reached the end of the division. The final quotient is 0.6. The remainder is 0, indicating that the division is exact:

___________
0.3 | 0.18
- 0.00
________
0.18
0

Therefore, 0.18 divided by 0.3 equals 0.6, with no remainder.
