Step 1
|                    | .In the first step, place the dividend | |
|             | (1,536) on the frame near the left side, leaving one column vacant for the quotient figure (fig 1). The process is the following: Divide the first figure of the dividend by the first figure of the divisor; Multiply the quotient thus obtained by the second figure of the divisor and subtract the product thus obtained from the dividend on the 2nd column from the quotient figure.Repeat | |
| fig 1 | until the entire dividend is finished. |
