666456 ÷ 10 
Our goal is to divide 666456 by 10.

Advancing to step 1:
If we divide 6 by 10, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 10

Advancing to step 2:
66 divided by 10 is 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 60 from 66, we get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 10

Let's proceed to step 3:
10 goes into 66 6 times with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 66.0
If we take 60 away from 66, we end up with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 10

Moving on to step 4:
If we divide 64 by 10, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 666.0
Subtract 60 from 64 to get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 10

On to step 5:
10 can be fit into 45 4 times, resulting in a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 6664.0
If we subtract 40 from 45, we get 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 10

Going ahead to step 6:
56 divided by 10 is 5 with a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 66645.0
Subtracting 50 from 56 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
10 can be fit into 60 6 times, resulting in a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 66645.6
If we take 60 away from 60, we end up 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.

On to step 8:
10 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 66645.6
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
The number 10 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 66645.6
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 66645.6 with a balance of 0.0.
