446159 divided by 15 
We want to figure out the number of times 446159 can be divided by 15.

Going ahead to step 1:
4 divided by 15 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 15

Advancing to step 2:
The number 15 fits into 44 2 times, leaving a remainder of 14.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 30 from 44 leaves us with 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 15

Let's proceed to step 3:
15 goes into 146 9 times with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Subtracting 135 from 146 leaves us with 11.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 15

Going ahead to step 4:
111 divided by 15 is 7 with a remainder of 6.
The next digit of our result is 7. 
Result so far: 297.0
The remainder is 6 after subtracting 105 from 111.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 15

Going ahead to step 5:
The number 15 fits into 65 4 times, leaving a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 2974.0
Subtracting 60 from 65 leaves us with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 15

Step 6:
59 divided by 15 is 3 with a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 29743.0
The remainder is 14 after subtracting 45 from 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 7:
When dividing 140 by 15, we get 9 with a remainder of 5.
The next digit of our result is 9. 
Result so far: 29743.9
Deduct 135 from 140 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.

On to step 8:
When dividing 50 by 15, we get 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 29743.93
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
15 goes into 50 3 times with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 29743.933
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.

The final outcome is 29743.933, with a leftover of 0.0005.
