660173 ÷ 10 
Our goal is to divide 660173 by 10.

Step 1:
10 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 10

Advancing to step 2:
When dividing 66 by 10, we get 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 60 from 66 leaves us with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 10

On to step 3:
If we divide 60 by 10, we get 6 and a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
Subtracting 60 from 60 leaves us with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 10

Going ahead to step 4:
10 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 660.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 10

Let's proceed to step 5:
17 divided by 10 is 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 6601.0
The remainder is 7 after subtracting 10 from 17.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 10

Step 6:
10 can be fit into 73 7 times, resulting in a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 66017.0
Subtract 70 from 73 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
When dividing 30 by 10, we get 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 66017.3
If we subtract 30 from 30, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
0 divided by 10 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 66017.3
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
0 divided by 10 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 66017.3
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 66017.3 and a remainder of 0.0.
