Example:— 90892150÷3567648.
Striking the dividend on the machine and then using 35 (according to the small figures on the keys) as a trial divisor, two strokes show that the first quotient figure is 2; therefore, move the right hand finger one column to the right on the large 2 key. The first of the remaining figures of the divisor (67648) being 6, count thus: "six, seven, eight," striking the key each count; (the next "remaining" figure being 7) move to the next 2 key and count "seven, eight," striking each count; move one key to the right and count "six, seven, eight," striking each count; move one key to the right and count "four, five. six, seven, eight;" move one key to the right and count "eight," but this being the last figure strike one time more. See Fig. A.
