Then read the remainders from bottom to top to get  100011

So     35₁₀   =   100011₂

Convert 35 from base 10 to base 2

$\begin{array}{|rclcl|} \hline 35 &=& 2\cdot {\color{blue}17} &+& \color{red} 1 \\ {\color{blue}17} &=& 2\cdot {\color{blue}8} &+& \color{red} 1 \\ {\color{blue}8} &=& 2\cdot {\color{blue}4} &+& \color{red} 0 \\ {\color{blue}4} &=& 2\cdot {\color{blue}2} &+& \color{red} 0 \\ {\color{blue}2} &=& 2\cdot {\color{blue}1} &+& \color{red} 0 \\ {\color{blue}1} &=& 2\cdot {\color{blue}0} &+& \color{red} 1 \\ \hline \end{array}$

$\mathbf{35_{10} = {\color{red}100011}_2}$
