$$\begin{aligned} \mathtt{1}\overset{\mathtt{{\scriptscriptstyle 6}}}{\cancel{\mathtt{7}}}\overset{\mathtt{{\scriptscriptstyle 14}}}{\cancel{\mathtt{4}}}\\ \mathtt{-\phantom{0}}\phantom{0}\mathtt{6}\mathtt{7}\\ \hline \mathtt{1}\mathtt{0}\mathtt{7} \end{aligned}$$

Borrow $10^{1}$, resulting in $6$ in the $10^{1}$ place, and $14$ in the $10^{0}$ place.

$7$ is the digit in the $10^{0}$ place. $14 \times 10^{0} - 7 \times 10^{0} = 7 \times 10^{0}$.

$0$ is the digit in the $10^{1}$ place. $6 \times 10^{1} - 6 \times 10^{1} = 0 \times 10^{1}$.

$1$ is the digit in the $10^{2}$ place. $1 \times 10^{2} - 0 \times 10^{2} = 1 \times 10^{2}$.
