Solve 42div10

$$42 \div 10$$

Evaluate

$$\frac{21}{5}=4.2$$

Steps For Long Division Method

Use the 1^{st} digit 4 from dividend 42

$$\begin{array}{l}\phantom{10)}\phantom{1}\\10\overline{)42}\\\end{array}$$

Since 4 is less than 10, use the next digit 2 from dividend 42 and add 0 to the quotient

$$\begin{array}{l}\phantom{10)}0\phantom{2}\\10\overline{)42}\\\end{array}$$

Use the 2^{nd} digit 2 from dividend 42

$$\begin{array}{l}\phantom{10)}0\phantom{3}\\10\overline{)42}\\\end{array}$$

Find closest multiple of 10 to 42. We see that 4 \times 10 = 40 is the nearest. Now subtract 40 from 42 to get reminder 2. Add 4 to quotient.

$$\begin{array}{l}\phantom{10)}04\phantom{4}\\10\overline{)42}\\\phantom{10)}\underline{\phantom{}40\phantom{}}\\\phantom{10)9}2\\\end{array}$$

Since 2 is less than 10, stop the division. The reminder is 2. The topmost line 04 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 4.

$$\text{Quotient: }4 \text{Reminder: }2$$

Factor

$$\frac{3 \cdot 7}{5} = 4\frac{1}{5} = 4.2$$
