In the present paper we consider a possibility of using stochastic simulation (Monte-Carlo) technique approach to the study of Galactic Cosmic Ray propagation in the Heliosphere. We developed a technique for calculation of the cosmic ray propagation in a spherically symmetric steady state approximation of the Heliosphere. A comparison of the calculation results with those obtained by other methods as well as with an analytical approximation shows a good agreement. Besides, in the frameworks of the approximation used, we calculated the solar modulation of monoenergetic fluxes of Galactic Cosmic Rays entering the Heliosphere, in the particle's energy range 0.1 - 15 GeV. We studied the details of the modulation in their dependence of the initial particle's energy. In particular, a linear scaling of particle's energy losses vs. diffusion time is shown.
