Solve 155div10=

$$155 \div 10 =$$

Evaluate

$$\frac{31}{2}=15.5$$

Steps For Long Division Method

Use the 1^{st} digit 1 from dividend 155

$$\begin{array}{l}\phantom{10)}\phantom{1}\\10\overline{)155}\\\end{array}$$

Since 1 is less than 10, use the next digit 5 from dividend 155 and add 0 to the quotient

$$\begin{array}{l}\phantom{10)}0\phantom{2}\\10\overline{)155}\\\end{array}$$

Use the 2^{nd} digit 5 from dividend 155

$$\begin{array}{l}\phantom{10)}0\phantom{3}\\10\overline{)155}\\\end{array}$$

Find closest multiple of 10 to 15. We see that 1 \times 10 = 10 is the nearest. Now subtract 10 from 15 to get reminder 5. Add 1 to quotient.

$$\begin{array}{l}\phantom{10)}01\phantom{4}\\10\overline{)155}\\\phantom{10)}\underline{\phantom{}10\phantom{9}}\\\phantom{10)9}5\\\end{array}$$

Use the 3^{rd} digit 5 from dividend 155

$$\begin{array}{l}\phantom{10)}01\phantom{5}\\10\overline{)155}\\\phantom{10)}\underline{\phantom{}10\phantom{9}}\\\phantom{10)9}55\\\end{array}$$

Find closest multiple of 10 to 55. We see that 5 \times 10 = 50 is the nearest. Now subtract 50 from 55 to get reminder 5. Add 5 to quotient.

$$\begin{array}{l}\phantom{10)}015\phantom{6}\\10\overline{)155}\\\phantom{10)}\underline{\phantom{}10\phantom{9}}\\\phantom{10)9}55\\\phantom{10)}\underline{\phantom{9}50\phantom{}}\\\phantom{10)99}5\\\end{array}$$

Since 5 is less than 10, stop the division. The reminder is 5. The topmost line 015 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 15.

$$\text{Quotient: }15 \text{Reminder: }5$$

Factor

$$\frac{31}{2} = 15\frac{1}{2} = 15.5$$
