The following steps for successive magnification to visualise 2.665 are:

(1) We observe that 2.665 is located somewhere between 2 and 3 on the number line. So, let us look at the portion of the number line between 2 and 3.

(2) We divide this portion into 10 equal parts and mark each point of division. The first mark to the right of 2 will represent 2.1, the next 2.2 and soon. Again we observe that 2.665 lies between 2.6 And 2.7.

(3) We mark these points A₁ and A₂ respectively. The first mark on the right side of A₁, will represent 2.61, the number 2.62, and soon. We observe 2.665 lies between 2.66 and 2.67.

(4) Let us mark 2.66 as B₁ and 2.67 as B₂. Again divide the B₁B₂ into ten equal parts. The first mark on the right side of B₁ will represent 2.661, then next 2.662, and so on.

Clearly, fifth point will represent 2.665.
