369866 ÷ 15 
Let's see how many times 15 fits into 369866.

Step 1:
If we divide 3 by 15, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 15

Step 2:
When dividing 36 by 15, we get 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 30 from 36 to get 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 15

Let's proceed to step 3:
If we divide 69 by 15, we get 4 and a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 24.0
Subtracting 60 from 69 leaves us with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 15

Moving on to step 4:
15 goes into 98 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 246.0
If we take 90 away from 98, we end up with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 15

Going ahead to step 5:
If we divide 86 by 15, we get 5 and a remainder of 11.
Record the quotient 5 as the next digit in the result. 
Result so far: 2465.0
Deduct 75 from 86 and we're left with 11.
Bring next digit (6) of the dividend behind the 11 and repeat the process: 116 / 15

Step 6:
15 goes into 116 7 times with a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 24657.0
The remainder is 11 after subtracting 105 from 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
15 can be fit into 110 7 times, resulting in a remainder of 5.
The next digit of our result is 7. 
Result so far: 24657.7
If we subtract 105 from 110, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 24657.73
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
15 goes into 50 3 times with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 24657.733
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

In conclusion, the division gives 24657.733 with a balance of 0.0005.
