Put zeros in the blank number places:

Place value	hundreds	tens	ones	.	tenths	hundredths

	2	0	0	,	0	0
-	1	1	5	,	4	7
				,

Because the upper digit (0) in the hundredths column is too small to get a positive difference, borrow 1 from the number to the left (200.0) which becomes (199.9) and get (10).

Place value	hundreds	tens	ones	.	tenths	hundredths
	1	9	9		9	10
	2	0	0	,	0	0
-	1	1	5	,	4	7
				,

Subtract the numbers in the hundredths column from the top number:
10-0-7=3

Place value	hundreds	tens	ones	.	tenths	hundredths
	1	9	9		9	10
	2	0	0	,	0	0
-	1	1	5	,	4	7
				,		3

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

Place value	hundreds	tens	ones	.	tenths	hundredths
	1	9	9		9	10
	2	0	0	,	0	0
-	1	1	5	,	4	7
				,	5	3

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

Place value	hundreds	tens	ones	.	tenths	hundredths
	1	9	9		9	10
	2	0	0	,	0	0
-	1	1	5	,	4	7
			4	,	5	3

Subtract the numbers in the tens column from the top number:
9-1=8

Place value	hundreds	tens	ones	.	tenths	hundredths
	1	9	9		9	10
	2	0	0	,	0	0
-	1	1	5	,	4	7
		8	4	,	5	3

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

Place value	hundreds	tens	ones	.	tenths	hundredths
	1	9	9		9	10
	2	0	0	,	0	0
-	1	1	5	,	4	7
	0	8	4	,	5	3

The solution is: 84,53
