Step-by-step explanation

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

Place value	tens	ones	.	tenths	hundredths	thousandths

	8	2	.	8	7
-	2	0	.	4	6	2
			.

Put zeros in the blank number places:

Place value	tens	ones	.	tenths	hundredths	thousandths

	8	2	.	8	7	0
-	2	0	.	4	6	2
			.

2. Subtract the numbers using long subtraction method

Because the upper digit (0) in the thousandths column is too small to get a positive difference, borrow 1 from the digit (7) in the next number place which becomes (6) and get (10).

Place value	tens	ones	.	tenths	hundredths	thousandths
					6	10
	8	2	.	8	7	0
-	2	0	.	4	6	2
			.

Subtract the numbers in the thousandths column from the top number:
10-0-2=8

Place value	tens	ones	.	tenths	hundredths	thousandths
					6	10
	8	2	.	8	7	0
-	2	0	.	4	6	2
			.			8

Subtract the numbers in the hundredths column from the top number:
6-6=0

Place value	tens	ones	.	tenths	hundredths	thousandths
					6	10
	8	2	.	8	7	0
-	2	0	.	4	6	2
			.		0	8

Subtract the numbers in the tenths column from the top number:
8-4=4

Place value	tens	ones	.	tenths	hundredths	thousandths
					6	10
	8	2	.	8	7	0
-	2	0	.	4	6	2
			.	4	0	8

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

Place value	tens	ones	.	tenths	hundredths	thousandths
					6	10
	8	2	.	8	7	0
-	2	0	.	4	6	2
		2	.	4	0	8

Subtract the numbers in the tens column from the top number:
8-2=6

Place value	tens	ones	.	tenths	hundredths	thousandths
					6	10
	8	2	.	8	7	0
-	2	0	.	4	6	2
	6	2	.	4	0	8

The solution is: 62.408
