Place value	tens	ones	.	tenths	hundredths	thousandths

			.

Put zeros in the blank number places:

Place value	tens	ones	.	tenths	hundredths	thousandths

	4	7	.	3	0	0
-		0	.	8	8	3
			.

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 (30) which becomes (29) and get (10).

Place value	tens	ones	.	tenths	hundredths	thousandths
				2	9	10
	4	7	.	3	0	0
-		0	.	8	8	3
			.

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

Place value	tens	ones	.	tenths	hundredths	thousandths
				2	9	10
	4	7	.	3	0	0
-		0	.	8	8	3
			.			7

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

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

Because the upper digit (2) in the tenths 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 (12).

Subtract the numbers in the tenths column from the top number:
12-8=4

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

Write 4 in the tens place.

The solution is: 46.417
