503389 divided by 15 
We want to divide 503389 by 15.

Let's proceed to step 1:
15 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 15

Step 2:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 5 after subtracting 45 from 50.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 15

Moving on to step 3:
15 goes into 53 3 times with a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 33.0
Subtracting 45 from 53 leaves us with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 15

Let's proceed to step 4:
If we divide 83 by 15, we get 5 and a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 335.0
If we subtract 75 from 83, we get 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 15

Going ahead to step 5:
If we divide 88 by 15, we get 5 and a remainder of 13.
Write down 5 as next digit of the result. 
Result so far: 3355.0
Subtracting 75 from 88 leaves us with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 15

Going ahead to step 6:
The number 15 fits into 139 9 times, leaving a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 33559.0
Subtract 135 from 139 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
When dividing 40 by 15, we get 2 with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 33559.2
The remainder is 10 after subtracting 30 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
The number 15 fits into 100 6 times, leaving a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 33559.26
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
15 goes into 100 6 times with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 33559.266
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 33559.266, with a leftover of 0.001.
