II. Division:
**9 से भाग
(i) 1 2 ÷ 9
1 | 2 ÷ 9
âäâ
1 | 3 Q = 1 R = 3
(ii) 1 2 3 ÷ 9
1 2 | 3 ÷ 9
âäâ ä â
1 3 | 6 Q = 13 R = 6
(iii) 1 2 3 4 ÷ 9
1 2 3 | 4 ÷ 9
1 3 6 | 10 [Now 10 ÷ 9 in (a)]
+ 1 | 1 Q = 137 R = 3
1 3 7 | 1
(a) 1 0 ÷ 9
1 | 0 ÷ 9
âäâ
1 | 1 Q = 1 R = 1
** Divide by 99
(iv) 1 2 3 4 ÷ 9 9
12 | 34 ÷ 99
12 | 46 Q = 12 R = 46
** Divide by 999
(iv) 1 2 3 4 ÷ 999
1 | 234 ÷ 999
1 | 235 Q = 1 R = 235

Forwards (Division) Method (by the Ekadhika-Purva Sutra)
By Vedic mental (one-line method)
The “ Sanskrit Sutra” (Formula) is Ekadhika Porven ;
(by the Ekadhika-Purva Sutra)
Backwards (Multiplication) Method.
We merely write down the 18-digit answer:
1/19 = 0.052631578-947368421
0.052631578
947368421
1/19 = 0.052631578-947368421
