When you divide 21 by 6, the result is 3.5. This means that 6 goes into 21 three times with a remainder of 3. To break it down further:
- 6 multiplied by 3 equals 18.
- Subtracting 18 from 21 leaves a remainder of 3.
- To express this remainder as a decimal, you divide 3 by 6, which equals 0.5.
- Adding this to the 3 gives you the final result of 3.5.
