\begin{array}{l}\phantom{38)}\phantom{1}\\38\overline{)46}\\\end{array}
Use the 1^{st} digit 4 from dividend 46
\begin{array}{l}\phantom{38)}0\phantom{2}\\38\overline{)46}\\\end{array}
Since 4 is less than 38, use the next digit 6 from dividend 46 and add 0 to the quotient
\begin{array}{l}\phantom{38)}0\phantom{3}\\38\overline{)46}\\\end{array}
Use the 2^{nd} digit 6 from dividend 46
\begin{array}{l}\phantom{38)}01\phantom{4}\\38\overline{)46}\\\phantom{38)}\underline{\phantom{}38\phantom{}}\\\phantom{38)9}8\\\end{array}
Find closest multiple of 38 to 46. We see that 1 \times 38 = 38 is the nearest. Now subtract 38 from 46 to get reminder 8. Add 1 to quotient.
\text{Quotient: }1 \text{Reminder: }8
Since 8 is less than 38, stop the division. The reminder is 8. The topmost line 01 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 1.
