Let's divide 668287 by 15
We want to figure out the number of times 668287 can be divided by 15.

Step 1:
If we divide 6 by 15, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 15

Advancing to step 2:
The number 15 fits into 66 4 times, leaving a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 60 from 66, we get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 15

Advancing to step 3:
15 goes into 68 4 times with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
The remainder is 8 after subtracting 60 from 68.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 15

Advancing to step 4:
82 divided by 15 is 5 with a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 445.0
The remainder is 7 after subtracting 75 from 82.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 15

Moving on to step 5:
15 can be fit into 78 5 times, resulting in a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 4455.0
If we take 75 away from 78, we end up with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 15

Moving on to step 6:
15 goes into 37 2 times with a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 44552.0
Subtracting 30 from 37 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
15 can be fit into 70 4 times, resulting in a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 44552.4
Subtract 60 from 70 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
If we divide 100 by 15, we get 6 and a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 44552.46
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
If we divide 100 by 15, we get 6 and a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 44552.466
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 44552.466 and a remainder of 0.001.
