\begin{array}{l}\phantom{100)}\phantom{1}\\100\overline{)115}\\\end{array}
Use the 1^{st} digit 1 from dividend 115
\begin{array}{l}\phantom{100)}0\phantom{2}\\100\overline{)115}\\\end{array}
Since 1 is less than 100, use the next digit 1 from dividend 115 and add 0 to the quotient
\begin{array}{l}\phantom{100)}0\phantom{3}\\100\overline{)115}\\\end{array}
Use the 2^{nd} digit 1 from dividend 115
\begin{array}{l}\phantom{100)}00\phantom{4}\\100\overline{)115}\\\end{array}
Since 11 is less than 100, use the next digit 5 from dividend 115 and add 0 to the quotient
\begin{array}{l}\phantom{100)}00\phantom{5}\\100\overline{)115}\\\end{array}
Use the 3^{rd} digit 5 from dividend 115
\begin{array}{l}\phantom{100)}001\phantom{6}\\100\overline{)115}\\\phantom{100)}\underline{\phantom{}100\phantom{}}\\\phantom{100)9}15\\\end{array}
Find closest multiple of 100 to 115. We see that 1 \times 100 = 100 is the nearest. Now subtract 100 from 115 to get reminder 15. Add 1 to quotient.
\text{Quotient: }1 \text{Reminder: }15
Since 15 is less than 100, stop the division. The reminder is 15. The topmost line 001 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 1.
