491897 ÷ 15 
Let's see how many times 15 fits into 491897.

Going ahead to step 1:
When dividing 4 by 15, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 15

Step 2:
49 divided by 15 is 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 45 from 49, we get 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 15

Advancing to step 3:
If we divide 41 by 15, we get 2 and a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 32.0
The remainder is 11 after subtracting 30 from 41.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 15

Step 4:
15 can be fit into 118 7 times, resulting in a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 327.0
The remainder is 13 after subtracting 105 from 118.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 15

Going ahead to step 5:
139 divided by 15 is 9 with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 3279.0
Subtract 135 from 139 to get 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 15

Advancing to step 6:
If we divide 47 by 15, we get 3 and a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 32793.0
If we subtract 45 from 47, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
When dividing 20 by 15, we get 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 32793.1
Subtracting 15 from 20 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.

Moving on to step 8:
50 divided by 15 is 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 32793.13
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.

Moving on to step 9:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 32793.133
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 result is 32793.133 with a remainder of 0.0005.
