666507 ÷ 15 
We want to divide 666507 by 15.

Advancing to step 1:
The number 15 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 15

Going ahead to step 2:
66 divided by 15 is 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 6 after subtracting 60 from 66.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 15

Let's proceed to step 3:
If we divide 66 by 15, we get 4 and a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 44.0
The remainder is 6 after subtracting 60 from 66.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 15

On to step 4:
The number 15 fits into 65 4 times, leaving a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 444.0
If we subtract 60 from 65, we get 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 15

Advancing to step 5:
15 goes into 50 3 times with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 4443.0
If we take 45 away from 50, we end up with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 15

Let's proceed to step 6:
15 goes into 57 3 times with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 44433.0
Deduct 45 from 57 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
If we divide 120 by 15, we get 8 and a remainder of 0.
The next digit of our result is 8. 
Result so far: 44433.8
If we subtract 120 from 120, 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:
15 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 44433.8
Deduct 0 from 0 and we're left 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.

Step 9:
If we divide 0 by 15, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 44433.8
Deduct 0 from 0 and we're left 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 44433.8 and a remainder of 0.0.
