Step-by-step explanation

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

Place value	ten millions	millions	hundred thousands	ten thousands	thousands	hundreds	tens	ones

	1	1	4	9	2	0	0	0
-		3	2	2	9	2	0	0

2. Subtract the numbers using long subtraction method

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

Place value	ten millions	millions	hundred thousands	ten thousands	thousands	hundreds	tens	ones

	1	1	4	9	2	0	0	0
-		3	2	2	9	2	0	0
								0

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

Place value	ten millions	millions	hundred thousands	ten thousands	thousands	hundreds	tens	ones

	1	1	4	9	2	0	0	0
-		3	2	2	9	2	0	0
							0	0

Because the upper digit (0) in the hundreds column is too small to get a positive difference, borrow 1 from the digit (2) in the next number place which becomes (1) and get (10).

Place value	ten millions	millions	hundred thousands	ten thousands	thousands	hundreds	tens	ones
					1	10
	1	1	4	9	2	0	0	0
-		3	2	2	9	2	0	0
							0	0

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

Place value	ten millions	millions	hundred thousands	ten thousands	thousands	hundreds	tens	ones
					1	10
	1	1	4	9	2	0	0	0
-		3	2	2	9	2	0	0
						8	0	0

Because the upper digit (1) in the thousands column is too small to get a positive difference, borrow 1 from the digit (9) in the next number place which becomes (8) and get (11).

Place value	ten millions	millions	hundred thousands	ten thousands	thousands	hundreds	tens	ones
				8	11
					1	10
	1	1	4	9	2	0	0	0
-		3	2	2	9	2	0	0
						8	0	0

Subtract the numbers in the thousands column from the top number:
11-9=2

Place value	ten millions	millions	hundred thousands	ten thousands	thousands	hundreds	tens	ones
				8	11
					1	10
	1	1	4	9	2	0	0	0
-		3	2	2	9	2	0	0
					2	8	0	0

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

Place value	ten millions	millions	hundred thousands	ten thousands	thousands	hundreds	tens	ones
				8	11
					1	10
	1	1	4	9	2	0	0	0
-		3	2	2	9	2	0	0
				6	2	8	0	0

Subtract the numbers in the hundred thousands column from the top number:
4-2=2

Place value	ten millions	millions	hundred thousands	ten thousands	thousands	hundreds	tens	ones
				8	11
					1	10
	1	1	4	9	2	0	0	0
-		3	2	2	9	2	0	0
			2	6	2	8	0	0

Because the upper digit (1) in the millions 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 (11).

Place value	ten millions	millions	hundred thousands	ten thousands	thousands	hundreds	tens	ones
	0	11
				8	11
					1	10
	1	1	4	9	2	0	0	0
-		3	2	2	9	2	0	0
			2	6	2	8	0	0

Subtract the numbers in the millions column from the top number:
11-3=8

Place value	ten millions	millions	hundred thousands	ten thousands	thousands	hundreds	tens	ones
	0	11
				8	11
					1	10
	1	1	4	9	2	0	0	0
-		3	2	2	9	2	0	0
		8	2	6	2	8	0	0

Write 0 in the ten millions place.

Place value	ten millions	millions	hundred thousands	ten thousands	thousands	hundreds	tens	ones
	0	11
				8	11
					1	10
	1	1	4	9	2	0	0	0
-		3	2	2	9	2	0	0
	0	8	2	6	2	8	0	0

The solution is: 8,262,800
