Step 1: Write both numbers in scientific notation. For more information, use the SN Converter.
$$ 0.356\cdot 10^{-1} = 0.356\cdot 10^{-1} $$$$ 0.156\cdot 10^{4} = 0.156\cdot 10^{4} $$Step 2: Divide the numeric parts. Note that in intermediate calculations, we need 6 significant digits.
$$ \frac{ 0.356 }{ 0.156 } \approx 2.28205 $$Step 3: Divide $10^{ -1 }$ by $10^{ 4 }$:
$$ \frac{ 10^{ -1 } }{ 10^{ 4 } } = 10^{ -1 - 4 } = 10^{ -5 } $$Step 4: Write the solution as the product of the numbers obtained in steps two and three.
$$ 2.28205 \cdot 10^{ -5 } $$
