We look at the division of 669885 by 15 
Let's see how many times 15 fits into 669885.

On to step 1:
15 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 15

Advancing to step 2:
15 goes into 66 4 times with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 60 away from 66, we end up with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 15

Advancing to step 3:
15 can be fit into 69 4 times, resulting in a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
The remainder is 9 after subtracting 60 from 69.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 15

Advancing to step 4:
If we divide 98 by 15, we get 6 and a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 446.0
Subtracting 90 from 98 leaves us with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 15

Let's proceed to step 5:
88 divided by 15 is 5 with a remainder of 13.
The next digit of our result is 5. 
Result so far: 4465.0
If we subtract 75 from 88, we get 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 15

Moving on to step 6:
The number 15 fits into 135 9 times, leaving a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 44659.0
Deduct 135 from 135 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.

On to step 7:
If we divide 0 by 15, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 44659.0
If we take 0 away from 0, 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.

Going ahead to step 8:
15 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: 44659.0
If we take 0 away from 0, 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.

The final result is 44659.0 with a remainder of 0.0.
