Long division with decimals follows the same rhythm as whole-number division. You still ask how many times the divisor fits into parts of the dividend, multiply, subtract, and bring down the next digit. The decimal point is the only extra detail to track.
If the divisor is a whole number and the dividend has a decimal, place the decimal point in the quotient directly above the decimal in the dividend. Then divide as usual. For 45.6 ÷ 3, the decimal sits between the ones and tenths in the answer, and you work through 3 into 45, then into the remaining digits.
When the divisor itself has a decimal, shift both numbers until the divisor becomes a whole number. Multiplying divisor and dividend by the same power of ten does not change the quotient. So 4.2 ÷ 0.6 becomes 42 ÷ 6 after multiplying both by 10. Once the divisor is whole, place the decimal in the quotient and continue.

Check your work with multiplication. Multiply the quotient by the divisor and see if you land near the original dividend, allowing for rounding. If you are far off, the decimal point usually drifted one place left or right.
Write neatly in columns. Misaligned digits cause more errors than the decimal rule itself. Graph paper or lined paper turned sideways helps keep places straight when you are learning.
For homework checks or multi-digit practice, a longdivisioncalculator.org can show the worked steps beside your own so you can spot where a subtraction or bring-down went wrong.end if you need more places. Dividing 1 by 8 gives 0.125 once you add zeros and keep going. Stop when the remainder is zero, when you reach the required decimal places, or when a repeating pattern appears.
Remainders still matter. A remainder of zero means the division finished cleanly. A looping remainder, such as when 1 ÷ 3 produces 0.333…, means the decimal repeats. Teachers often ask for a bar over the repeating digit or for a rounded answer to a set number of places.
Money problems are everyday decimal division. Splitting a $47.50 bill three ways is 47.50 ÷ 3. Keep two decimal places for currency, and decide how to handle leftover cents in real life even if the math shows a repeating digit.
