It is calculated according to the principle of how many times the divisor is enlarged at the same time.

Give you a few examples.

12. 1? ÷? 1. 1? = 12 1? ÷? 1 1=? 1 1

62.5? ÷? 25? =? 2.5

1.44? ÷? 12? =0. 12

Approximation of fractional division quotient

Is to continue calculating the division with remainder.

If you want to keep a few decimal places, count one more.

take for example

Keep two decimal places, even three.

See if the third place is greater than or equal to 5,

When the third number is greater than or equal to 5, enter 1 in the second number.

When it is less than 5, it is discarded and only the first two digits are taken.

Give you a separate example:

12.4? ÷? 1. 1

= 124? ÷? 1 1?

≈ 1 1.272

≈ 1 1.27

6.32÷0. 13

≈632? ÷? 13?

≈48.6 15

≈48.62
