Solve 158div20

$$158 \div 20$$

Evaluate

$$\frac{79}{10}=7.9$$

Steps For Long Division Method

Use the 1^{st} digit 1 from dividend 158

$$\begin{array}{l}\phantom{20)}\phantom{1}\\20\overline{)158}\\\end{array}$$

Since 1 is less than 20, use the next digit 5 from dividend 158 and add 0 to the quotient

$$\begin{array}{l}\phantom{20)}0\phantom{2}\\20\overline{)158}\\\end{array}$$

Use the 2^{nd} digit 5 from dividend 158

$$\begin{array}{l}\phantom{20)}0\phantom{3}\\20\overline{)158}\\\end{array}$$

Since 15 is less than 20, use the next digit 8 from dividend 158 and add 0 to the quotient

$$\begin{array}{l}\phantom{20)}00\phantom{4}\\20\overline{)158}\\\end{array}$$

Use the 3^{rd} digit 8 from dividend 158

$$\begin{array}{l}\phantom{20)}00\phantom{5}\\20\overline{)158}\\\end{array}$$

Find closest multiple of 20 to 158. We see that 7 \times 20 = 140 is the nearest. Now subtract 140 from 158 to get reminder 18. Add 7 to quotient.

$$\begin{array}{l}\phantom{20)}007\phantom{6}\\20\overline{)158}\\\phantom{20)}\underline{\phantom{}140\phantom{}}\\\phantom{20)9}18\\\end{array}$$

Since 18 is less than 20, stop the division. The reminder is 18. The topmost line 007 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 7.

$$\text{Quotient: }7 \text{Reminder: }18$$

Factor

$$\frac{79}{2 \cdot 5} = 7\frac{9}{10} = 7.9$$
