Fill specific cell depending on the number provided in a cell

[ifticalgary]

Kindly help with the following problem example if somebody has knowledge to solve it.

Problem: Fill specific cell automatically depending on the number provided in one cell.

Example:
Any value ranging from 0.1 to 2.0 is entered in Cell “B1”.
Depending on the value provided in Cell “B1”, a cell needs to be automatically filled with this number.

For e.g:
Any number from 0.1 to 0.5 is entered in Cell “B1”, the number will also be filled in Cell “D1”.
Any number from 0.1 to 0.5 is entered in Cell “B1”, the number will also be filled in Cell “D2”.
Any number from 0.1 to 0.5 is entered in Cell “B1”, the number will also be filled in Cell “D3”.
Any number from 0.1 to 0.5 is entered in Cell “B1”, the number will also be filled in Cell “D4”.

I do appreciate in advance for helping me for solving my problem and bit ashamed for having little knowledge of Excel.

Regards
