Place value	tens	ones	.	tenths	hundredths	thousandths

	5	1	,	6

Put zeros in the blank number places:

Place value	tens	ones	.	tenths	hundredths	thousandths

	5	1	,	6	0	0
-		0	,	6	2	4
			,

Because the upper digit (0) in the thousandths 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	tens	ones	.	tenths	hundredths	thousandths
				5	9	10
	5	1	,	6	0	0
-		0	,	6	2	4

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

Place value	tens	ones	.	tenths	hundredths	thousandths
				5	9	10
	5	1	,	6	0	0

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

Place value	tens	ones	.	tenths	hundredths	thousandths

			,		7	6

Because the upper digit (5) in the tenths column is too small to get a positive difference, borrow 1 from the digit (1) in the next number place which becomes (0) and get (15).

Subtract the numbers in the tenths column from the top number:
15-6=9

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

Write 5 in the tens place.

The solution is: 50,976
