Unfortunately, the browser used for posting questions is hopelessly inadequate for mathematics: it strips away most symbols. All that we can see is "40.065.23". From that it is not at all clear whether you mean 40.0 and 65.23 or 40.06 and 5.23 or even 40.065 and .23 It makes little sense for me to try and guess - I may as well make up my own questions and answer them!
To estimate a quotient, one common method is rounding the dividend and divisor to the nearest convenient numbers, which simplifies mental calculations. Another approach is using compatible numbers, where the divisor is adjusted to a number that divides the dividend more easily. Additionally, long division can be used for a more precise estimate, while recognizing patterns in division can also aid in quick estimates. Each of these methods allows for quicker approximations without requiring exact calculations.
To estimate the quotient, we first round off the divisor and the dividend to the nearest tens, hundreds, or thousands and then divide the rounded numbers. In a division sum, when the divisor is made up of 2 digits or more than 2 digits, it helps if we first estimate the quotient and then try to find the actual number.

If 19.73 is the quotient, it could be estimated at 20 to the nearest ten. If you mean to divide 19 into 73, 20/80 = 0.25

Well, honey, it's simple. Round that decimal to the nearest whole number, then divide it by the whole number. For example, if you have 7.2 ÷ 3, round 7.2 to 7, then divide 7 by 3 to get your estimate. Easy peasy lemon squeezy!
