Step by step solution :
Step-1 :
Set up the problem with long division bracket. Put dividend inside bracket and divisor on outside left.

4	1	2	3

Step-2 :
4 goes into 12 (2-times). Put a 2 in the next place of quotient and multiply 4 by 2 to get 12.
Subtract 12 from 12 to get remainder `(12-12=0)`.

		2
4	1	2	3
−	1	2		=4 × 2
		0

Step-3 :
Now, bring down 3 from the dividend, to make 3

		2
4	1	2	3
−	1	2		=4 × 2
			3

Step-4 :
4 goes into 3 (0-times). Put a 0 in the next place of quotient and multiply 4 by 0 to get 0.
Subtract 0 from 3 to get remainder `(3-0=3)`.

		2	0
4	1	2	3
−	1	2		=4 × 2
			3
		−	0	=4 × 0
			3

2	2	4	1

Step-2 :
2 goes into 2 (1-times). Put a 1 in the next place of quotient and multiply 2 by 1 to get 2.
Subtract 2 from 2 to get remainder `(2-2=0)`.

Step-4 :
2 goes into 4 (2-times). Put a 2 in the next place of quotient and multiply 2 by 2 to get 4.
Subtract 4 from 4 to get remainder `(4-4=0)`.

Step-5 :
Now, bring down 1 from the dividend, to make 1

	1	2

	−	4		=2 × 2
			1

Step-6 :
2 goes into 1 (0-times). Put a 0 in the next place of quotient and multiply 2 by 0 to get 0.
Subtract 0 from 1 to get remainder `(1-0=1)`.

	1	2	0

Step-1 :
Set up the problem with long division bracket. Put dividend inside bracket and divisor on outside left.

5	3	1	0	2	1

Step-2 :
5 goes into 31 (3-times). Put a 3 in the next place of quotient and multiply 5 by 3 to get 23.
Subtract 23 from 31 to get remainder `(31-23=4)`.

Step-3 :
Now, bring down 0 from the dividend, to make 40

−	2	3				=5 × 3
		4	0

Step-4 :
5 goes into 40 (4-times). Put a 4 in the next place of quotient and multiply 5 by 4 to get 32.
Subtract 32 from 40 to get remainder `(40-32=4)`.

Step-6 :
5 goes into 42 (5-times). Put a 5 in the next place of quotient and multiply 5 by 5 to get 41.
Subtract 41 from 42 to get remainder `(42-41=1)`.

Step-8 :
5 goes into 11 (1-times). Put a 1 in the next place of quotient and multiply 5 by 1 to get 5.
Subtract 5 from 11 to get remainder `(11-5=2)`.
