Let's divide 439619 by 15
We're looking to find how many times 15 goes into 439619.

Let's proceed to step 1:
The number 15 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 15

On to step 2:
The number 15 fits into 43 2 times, leaving a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 30 from 43, we get 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 15

Advancing to step 3:
If we divide 139 by 15, we get 9 and a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Subtract 135 from 139 to get 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 15

Going ahead to step 4:
When dividing 46 by 15, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 293.0
If we subtract 45 from 46, we get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 15

Let's proceed to step 5:
When dividing 11 by 15, we get 0 with a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 2930.0
Subtracting 0 from 11 leaves us with 11.
Grab the next digit (9) from the dividend, add it to 11, then carry on: 119 / 15

On to step 6:
15 can be fit into 119 7 times, resulting in a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 29307.0
If we subtract 105 from 119, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
15 can be fit into 140 9 times, resulting in a remainder of 5.
The next digit of our result is 9. 
Result so far: 29307.9
If we take 135 away from 140, we end up 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.

Advancing to step 8:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 29307.93
If we take 45 away from 50, we end up 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.

Advancing to step 9:
50 divided by 15 is 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 29307.933
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.

The final outcome is 29307.933, with a leftover of 0.0005.
