Let's divide 137449 by 15
Let's see how many times 15 fits into 137449.

Going ahead to step 1:
15 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 15

Moving on to step 2:
13 divided by 15 is 0 with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 15

Advancing to step 3:
If we divide 137 by 15, we get 9 and a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 135 from 137, we get 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 15

Let's proceed to step 4:
When dividing 24 by 15, we get 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 91.0
Subtracting 15 from 24 leaves us with 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 15

Going ahead to step 5:
15 goes into 94 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 916.0
Deduct 90 from 94 and we're left with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 15

Step 6:
15 can be fit into 49 3 times, resulting in a remainder of 4.
The next digit of our result is 3. 
Result so far: 9163.0
The remainder is 4 after subtracting 45 from 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
The number 15 fits into 40 2 times, leaving a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 9163.2
If we subtract 30 from 40, 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:
If we divide 100 by 15, we get 6 and a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 9163.26
If we take 90 away from 100, we end up 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.

Going ahead to step 9:
15 goes into 100 6 times with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 9163.266
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.

The final result is 9163.266 with a remainder of 0.001.
