==== Placing the quotient figure ====
The interim quotient figure is placed in one of the two columns directly to the left of the dividend. To decide which one we need to compare the divisor with an equal number of the first digits of the dividend, adding zeros to its right if necessary:
; Dividend greater than or equal to the divisor
: the quotient is arranged in the second column to the left of the first digit of the dividend
: Example:
:{| class="wikitable" style="font-family:Courier; line-height: 1.10em;"
