When you divide 15 by 4, the result is 3.75. Here’s how it works:
1. **Division Process**: 4 goes into 15 three times (since 4 x 3 = 12).
2. **Subtract**: Subtract 12 from 15, which leaves a remainder of 3.
3. **Decimal Point**: To continue the division, add a decimal point and a zero to the remainder, making it 30.
4. **Continue Dividing**: 4 goes into 30 seven times (since 4 x 7 = 28).
5. **Subtract Again**: Subtract 28 from 30, leaving a remainder of 2.
6. **Final Step**: Add another zero to the remainder, making it 20. 4 goes into 20 exactly five times (since 4 x 5 = 20).
So, 15 divided by 4 equals 3.75. This means that 4 fits into 15 three and three-quarters times.
