Answer :

Sure, let's solve these division problems step-by-step:

1. First Division: [tex]\( 126 \div 4 \)[/tex]

To divide 126 by 4, you can follow these steps:

- First, see how many times 4 goes into 12 (the first two digits of 126). It goes 3 times because [tex]\( 4 \times 3 = 12 \)[/tex].
- Subtract 12 from 12, which gives 0, then bring down the next digit, 6.
- Now, see how many times 4 goes into 6. It goes 1 time because [tex]\( 4 \times 1 = 4 \)[/tex].
- Subtract 4 from 6, which leaves a remainder of 2.
- Since there are no more digits to bring down, you include the remainder as a decimal.
- Thus, 126 divided by 4 results in 31.5.

2. Second Division: [tex]\( 80 \div 1 \)[/tex]

Any number divided by 1 is the number itself. So, 80 divided by 1 is 80.

3. Third Division: [tex]\( 80 \div 5 \)[/tex]

To divide 80 by 5, perform the division as follows:

- Determine how many times 5 goes into 8 (the first digit of 80). It goes 1 time because [tex]\( 5 \times 1 = 5 \)[/tex].
- Subtract 5 from 8, which leaves 3. Bring down the next digit, 0, making it 30.
- Now, determine how many times 5 goes into 30. It goes 6 times because [tex]\( 5 \times 6 = 30 \)[/tex].
- Subtract 30 from 30, with no remainder left.
- Thus, 80 divided by 5 equals 16.

So, the results are:

- [tex]\( 126 \div 4 = 31.5 \)[/tex]
- [tex]\( 80 \div 1 = 80 \)[/tex]
- [tex]\( 80 \div 5 = 16 \)[/tex]
