Put zeros in the blank number places:

Place value	tens	ones	.	tenths	hundredths	thousandths

	7	0	,	0	0	0
-		7	,	9	4	8
			,

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 (70.00) which becomes (69.99) and get (10).

Place value	tens	ones	.	tenths	hundredths	thousandths
	6	9		9	9	10
	7	0	,	0	0	0
-		7	,	9	4	8
			,

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

Place value	tens	ones	.	tenths	hundredths	thousandths
	6	9		9	9	10
	7	0	,	0	0	0
-		7	,	9	4	8
			,			2

Subtract the numbers in the hundredths column from the top number:
9-4=5

Place value	tens	ones	.	tenths	hundredths	thousandths
	6	9		9	9	10
	7	0	,	0	0	0
-		7	,	9	4	8
			,		5	2

Subtract the numbers in the tenths column from the top number:
9-9=0

Place value	tens	ones	.	tenths	hundredths	thousandths
	6	9		9	9	10
	7	0	,	0	0	0
-		7	,	9	4	8
			,	0	5	2

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

Place value	tens	ones	.	tenths	hundredths	thousandths
	6	9		9	9	10
	7	0	,	0	0	0
-		7	,	9	4	8
		2	,	0	5	2

Write 6 in the tens place.

Place value	tens	ones	.	tenths	hundredths	thousandths
	6	9		9	9	10
	7	0	,	0	0	0
-		7	,	9	4	8
	6	2	,	0	5	2

The solution is: 62,052
