We're dividing 574789 by 15 
We're looking to find how many times 15 goes into 574789.

Moving on to step 1:
The number 15 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 15

On to step 2:
15 goes into 57 3 times with a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 45 from 57 leaves us with 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 15

Step 3:
When dividing 124 by 15, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 38.0
If we subtract 120 from 124, we get 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 15

Let's proceed to step 4:
The number 15 fits into 47 3 times, leaving a remainder of 2.
The next digit of our result is 3. 
Result so far: 383.0
If we take 45 away from 47, we end up with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 15

Let's proceed to step 5:
15 can be fit into 28 1 times, resulting in a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 3831.0
Deduct 15 from 28 and we're left with 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 15

Going ahead to step 6:
15 can be fit into 139 9 times, resulting in a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 38319.0
If we take 135 away from 139, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
40 divided by 15 is 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 38319.2
Subtracting 30 from 40 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.

Step 8:
15 can be fit into 100 6 times, resulting in a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 38319.26
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.

Going ahead to step 9:
When dividing 100 by 15, we get 6 with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 38319.266
Subtract 90 from 100 to 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 outcome is 38319.266, with a leftover of 0.001.
