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

	3	0	1	0	7	0	6	1
-		3	0	6	6	0	0	1

2. Subtract the numbers using long subtraction method

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

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

	3	0	1	0	7	0	6	1
-		3	0	6	6	0	0	1
								0

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

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

	3	0	1	0	7	0	6	1
-		3	0	6	6	0	0	1
							6	0

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

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

	3	0	1	0	7	0	6	1
-		3	0	6	6	0	0	1
						0	6	0

Subtract the numbers in the thousands column from the top number:
7-6=1

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

	3	0	1	0	7	0	6	1
-		3	0	6	6	0	0	1
					1	0	6	0

Because the upper digit (0) in the ten thousands 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 (10).

Place value	ten millions	millions	hundred thousands	ten thousands	thousands	hundreds	tens	ones
			0	10
	3	0	1	0	7	0	6	1
-		3	0	6	6	0	0	1
					1	0	6	0

Subtract the numbers in the ten thousands column from the top number:
10-6=4

Place value	ten millions	millions	hundred thousands	ten thousands	thousands	hundreds	tens	ones
			0	10
	3	0	1	0	7	0	6	1
-		3	0	6	6	0	0	1
				4	1	0	6	0

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

Place value	ten millions	millions	hundred thousands	ten thousands	thousands	hundreds	tens	ones
			0	10
	3	0	1	0	7	0	6	1
-		3	0	6	6	0	0	1
			0	4	1	0	6	0

Because the upper digit (0) in the millions column is too small to get a positive difference, borrow 1 from the digit (3) in the next number place which becomes (2) and get (10).

Place value	ten millions	millions	hundred thousands	ten thousands	thousands	hundreds	tens	ones
	2	10
			0	10
	3	0	1	0	7	0	6	1
-		3	0	6	6	0	0	1
			0	4	1	0	6	0

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

Place value	ten millions	millions	hundred thousands	ten thousands	thousands	hundreds	tens	ones
	2	10
			0	10
	3	0	1	0	7	0	6	1
-		3	0	6	6	0	0	1
		7	0	4	1	0	6	0

Write 2 in the ten millions place.

Place value	ten millions	millions	hundred thousands	ten thousands	thousands	hundreds	tens	ones
	2	10
			0	10
	3	0	1	0	7	0	6	1
-		3	0	6	6	0	0	1
	2	7	0	4	1	0	6	0

The solution is: 27,041,060
