\begin{array}{l}\phantom{70)}\phantom{1}\\70\overline{)105}\\\end{array}
Use the 1^{st} digit 1 from dividend 105
\begin{array}{l}\phantom{70)}0\phantom{2}\\70\overline{)105}\\\end{array}
Since 1 is less than 70, use the next digit 0 from dividend 105 and add 0 to the quotient
\begin{array}{l}\phantom{70)}0\phantom{3}\\70\overline{)105}\\\end{array}
Use the 2^{nd} digit 0 from dividend 105
\begin{array}{l}\phantom{70)}00\phantom{4}\\70\overline{)105}\\\end{array}
Since 10 is less than 70, use the next digit 5 from dividend 105 and add 0 to the quotient
\begin{array}{l}\phantom{70)}00\phantom{5}\\70\overline{)105}\\\end{array}
Use the 3^{rd} digit 5 from dividend 105
\begin{array}{l}\phantom{70)}001\phantom{6}\\70\overline{)105}\\\phantom{70)}\underline{\phantom{9}70\phantom{}}\\\phantom{70)9}35\\\end{array}
Find closest multiple of 70 to 105. We see that 1 \times 70 = 70 is the nearest. Now subtract 70 from 105 to get reminder 35. Add 1 to quotient.
\text{Quotient: }1 \text{Reminder: }35
Since 35 is less than 70, stop the division. The reminder is 35. The topmost line 001 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 1.
