Whats the name of the number under the dividend? (Not the remainder)

divisor

1/2

1 is the dividend
2 is the divisor

Yes but the number that gets subtracted from the dividend. Sorry I wasn't clear.

I couldn't find a specific name for it. Perhaps one of these images will help you.

The number directly under the dividend in a division problem is called the quotient. The quotient represents the result of dividing the dividend by the divisor.

To find the quotient in a division problem, you need to perform the division operation. Here's an example to illustrate:

Let's say we have the division problem: 30 ÷ 6.

To find the quotient:
1. Start by dividing the first digit of the dividend (3) by the divisor (6), which gives us 0. Write this digit above the division symbol.
2. Multiply the quotient (0) by the divisor (6), which gives us 0.
3. Subtract this result (0) from the first digit of the dividend (3), which gives us 3.
4. Bring down the next digit of the dividend (0) next to the 3, giving us 30.
5. Divide the new number (30) by the divisor (6), which gives us 5. Write this digit above the division symbol.
6. Multiply the new quotient (5) by the divisor (6), giving us 30.
7. Subtract this result (30) from the new number (30), which leaves us with 0.

Therefore, in this example, the quotient is 5.
