Before implementing the process of division, you must be able to use multiplication table up to 9 x 9 and perform subtraction using abacus.
Introduction

Division Using Abacus
• (A) PLACES OF DIVIDEND
1. 1D ÷ 1D (e.g 9 ÷ 9)
Place the dividend on the 2nd rod from the place value of “ONES”
2. 2D ÷ 1D (e.g 46 ÷ 2)
Place the dividend on the 1st rod from the place value of “ONES”

Division Using Abacus
• (A) PLACES OF DIVIDEND
3. 3D ÷ 1D (e.g 833 ÷ 7)
Place the dividend on the rod of “ONES”
4. 4D ÷ 1D (e.g 9613 ÷ 8)
Place the dividend on the rod of “TENS”

(B) Placing of the quotient
If the first digit of the dividend is
greater or equal to the divisor, skip
one rod to the left of the dividend.

(B) Placing of the quotient
If the first digit of the dividend is
less than the divisor, place the
quotient next (to the left) to the
dividend.

(C) Minus the Dividend with the Product
Quotient x Divisore.g 72 ÷ 8 =9
Quotient x Divisor
e.g 9 x 8
So, down 72 at the dividend
