We divide 187903 by 15
Let's see how many times 15 fits into 187903.

Advancing to step 1:
1 divided by 15 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 15

On to step 2:
15 can be fit into 18 1 times, resulting in a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 15 away from 18, we end up with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 15

Advancing to step 3:
15 goes into 37 2 times with a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 30 away from 37, we end up with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 15

Step 4:
The number 15 fits into 79 5 times, leaving a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 125.0
Subtracting 75 from 79 leaves us with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 15

Let's proceed to step 5:
The number 15 fits into 40 2 times, leaving a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 1252.0
The remainder is 10 after subtracting 30 from 40.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 15

Moving on to step 6:
15 can be fit into 103 6 times, resulting in a remainder of 13.
Record the quotient 6 as the next digit in the result. 
Result so far: 12526.0
Deduct 90 from 103 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
The number 15 fits into 130 8 times, leaving a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 12526.8
If we subtract 120 from 130, 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.

Let's proceed to step 8:
The number 15 fits into 100 6 times, leaving a remainder of 10.
The next digit of our result is 6. 
Result so far: 12526.86
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.

Let's proceed to step 9:
100 divided by 15 is 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 12526.866
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 quotient of the division is 12526.866, and the remainder is 0.001.
