We divide 443918 by 15
We're looking to find how many times 15 goes into 443918.

Going ahead to step 1:
When dividing 4 by 15, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 15

Step 2:
If we divide 44 by 15, we get 2 and a remainder of 14.
The next digit of our result is 2. 
Result so far: 2.0
If we take 30 away from 44, we end up with 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 15

Step 3:
143 divided by 15 is 9 with a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Deduct 135 from 143 and we're left with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 15

Let's proceed to step 4:
The number 15 fits into 89 5 times, leaving a remainder of 14.
The next digit of our result is 5. 
Result so far: 295.0
Subtracting 75 from 89 leaves us with 14.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 15

Moving on to step 5:
15 can be fit into 141 9 times, resulting in a remainder of 6.
The next digit of our result is 9. 
Result so far: 2959.0
If we take 135 away from 141, we end up with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 15

On to step 6:
When dividing 68 by 15, we get 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 29594.0
If we take 60 away from 68, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
When dividing 80 by 15, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 29594.5
Subtracting 75 from 80 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.

On to step 8:
The number 15 fits into 50 3 times, leaving a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 29594.53
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.

Advancing to step 9:
15 can be fit into 50 3 times, resulting in a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 29594.533
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.

The final outcome is 29594.533, with a leftover of 0.0005.
