603828 divided by 15 
We want to divide 603828 by 15.

Step 1:
The number 15 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 15

Moving on to step 2:
If we divide 60 by 15, we get 4 and a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 60 from 60 and we're left with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 15

Advancing to step 3:
When dividing 3 by 15, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 40.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 15

Advancing to step 4:
The number 15 fits into 38 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 402.0
Deduct 30 from 38 and we're left with 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 15

Going ahead to step 5:
When dividing 82 by 15, we get 5 with a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 4025.0
If we take 75 away from 82, we end up with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 15

Advancing to step 6:
The number 15 fits into 78 5 times, leaving a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 40255.0
Deduct 75 from 78 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
30 divided by 15 is 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 40255.2
If we subtract 30 from 30, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
The number 15 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 40255.2
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
15 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 40255.2
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 40255.2 with a balance of 0.0.
