5. Divide 4723 by 5.
Answer:
Long Division: Steps in Dividing Whole NumbersExample: 4716 5
STEPS
1. The dividend is 4716. The divisor is 5. Write the dividend under the division house.
2. Divide 47 by 5. Write 9 above 7.
3. Multiply 9 by 5 and subtract.
4. Bring down the next digit, 1. Divide 21 by 5. Write 4 above 1.
5. Multiply 4 by 5 and subtract.
6. Bring down the next digit, 6. Divide 16 by 5. Write 3 above 6.
7. Multiply 3 by 5 and subtract.
8. The remainder 1 is less than the divisor 5. Stop. Write the quotient and the remainder.
