Step-by-step explanation

1. Rewrite the numbers from top to bottom, aligned by their place values

Place value	ones	.	tenths	hundredths	thousandths	ten thousandths	hundred thousandths	millionths

	0	.	0	0	0	1	3
-	0	.	0	0	0	0	0	4
		.

Put zeros in the blank number places:

Place value	ones	.	tenths	hundredths	thousandths	ten thousandths	hundred thousandths	millionths

	0	.	0	0	0	1	3	0
-	0	.	0	0	0	0	0	4
		.

2. Subtract the numbers using long subtraction method

Because the upper digit (0) in the millionths column is too small to get a positive difference, borrow 1 from the digit (3) in the next number place which becomes (2) and get (10).

Place value	ones	.	tenths	hundredths	thousandths	ten thousandths	hundred thousandths	millionths
							2	10
	0	.	0	0	0	1	3	0
-	0	.	0	0	0	0	0	4
		.

Subtract the numbers in the millionths column from the top number:
10-0-4=6

Place value	ones	.	tenths	hundredths	thousandths	ten thousandths	hundred thousandths	millionths
							2	10
	0	.	0	0	0	1	3	0
-	0	.	0	0	0	0	0	4
		.						6

Subtract the numbers in the hundred thousandths column from the top number:
2-0=2

Place value	ones	.	tenths	hundredths	thousandths	ten thousandths	hundred thousandths	millionths
							2	10
	0	.	0	0	0	1	3	0
-	0	.	0	0	0	0	0	4
		.					2	6

Subtract the numbers in the ten thousandths column from the top number:
1-0=1

Place value	ones	.	tenths	hundredths	thousandths	ten thousandths	hundred thousandths	millionths
							2	10
	0	.	0	0	0	1	3	0
-	0	.	0	0	0	0	0	4
		.				1	2	6

Subtract the numbers in the thousandths column from the top number:
0-0=0

Place value	ones	.	tenths	hundredths	thousandths	ten thousandths	hundred thousandths	millionths
							2	10
	0	.	0	0	0	1	3	0
-	0	.	0	0	0	0	0	4
		.			0	1	2	6

Subtract the numbers in the hundredths column from the top number:
0-0=0

Place value	ones	.	tenths	hundredths	thousandths	ten thousandths	hundred thousandths	millionths
							2	10
	0	.	0	0	0	1	3	0
-	0	.	0	0	0	0	0	4
		.		0	0	1	2	6

Subtract the numbers in the tenths column from the top number:
0-0=0

Place value	ones	.	tenths	hundredths	thousandths	ten thousandths	hundred thousandths	millionths
							2	10
	0	.	0	0	0	1	3	0
-	0	.	0	0	0	0	0	4
		.	0	0	0	1	2	6

Subtract the numbers in the ones column from the top number:
0-0=0

Place value	ones	.	tenths	hundredths	thousandths	ten thousandths	hundred thousandths	millionths
							2	10
	0	.	0	0	0	1	3	0
-	0	.	0	0	0	0	0	4
	0	.	0	0	0	1	2	6

The solution is: 0.000126
