591488 divided by 15 
We're looking to find how many times 15 goes into 591488.

Moving on to step 1:
15 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 15

Moving on to step 2:
59 divided by 15 is 3 with a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 45 from 59 to get 14.
Append the next digit (1) from the dividend to 14 and continue with: 141 / 15

Advancing to step 3:
15 can be fit into 141 9 times, resulting in a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 39.0
If we subtract 135 from 141, we get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 15

On to step 4:
64 divided by 15 is 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 394.0
If we take 60 away from 64, we end up with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 15

Let's proceed to step 5:
48 divided by 15 is 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 3943.0
Subtract 45 from 48 to get 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 15

Step 6:
If we divide 38 by 15, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 39432.0
Deduct 30 from 38 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
If we divide 80 by 15, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 39432.5
If we subtract 75 from 80, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
When dividing 50 by 15, we get 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 39432.53
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.

Advancing to step 9:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 39432.533
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.

Our division results in 39432.533 with a remaining 0.0005.
