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	ten millionths	hundred millionths

	0	.	0	0	0	0	1	6
-	0	.	0	0	0	0	0	0	2	5
		.

Put zeros in the blank number places:

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

	0	.	0	0	0	0	1	6	0	0
-	0	.	0	0	0	0	0	0	2	5
		.

2. Subtract the numbers using long subtraction method

Because the upper digit (0) in the hundred millionths column is too small to get a positive difference, borrow 1 from the number to the left (60) which becomes (59) and get (10).

Place value	ones	.	tenths	hundredths	thousandths	ten thousandths	hundred thousandths	millionths	ten millionths	hundred millionths
								5	9	10
	0	.	0	0	0	0	1	6	0	0
-	0	.	0	0	0	0	0	0	2	5
		.

Subtract the numbers in the hundred millionths column from the top number:
10-0-5=5

Place value	ones	.	tenths	hundredths	thousandths	ten thousandths	hundred thousandths	millionths	ten millionths	hundred millionths
								5	9	10

-	0	.	0	0	0	0	0	0	2	5
		.								5

Subtract the numbers in the ten millionths column from the top number:
9-2=7

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

	0	.	0	0	0	0	1	6	0	0
-	0	.	0	0	0	0	0	0	2	5
		.				0	1	5	7	5

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	ten millionths	hundred millionths
								5	9	10
	0	.	0	0	0	0	1	6	0	0
