We're dividing 595078 by 15 
Let's see how many times 15 fits into 595078.

Advancing to step 1:
15 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 15

On to step 2:
The number 15 fits into 59 3 times, leaving a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 45 from 59 and we're left with 14.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 15

Step 3:
15 goes into 145 9 times with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Subtract 135 from 145 to get 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 15

Advancing to step 4:
15 goes into 100 6 times with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 396.0
Subtracting 90 from 100 leaves us with 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 15

Advancing to step 5:
15 goes into 107 7 times with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 3967.0
If we take 105 away from 107, we end up with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 15

Advancing to step 6:
15 can be fit into 28 1 times, resulting in a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 39671.0
If we take 15 away from 28, we end up 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.

Let's proceed to step 7:
15 can be fit into 130 8 times, resulting in a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 39671.8
Subtracting 120 from 130 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.

Advancing to step 8:
15 can be fit into 100 6 times, resulting in a remainder of 10.
The next digit of our result is 6. 
Result so far: 39671.86
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.

Advancing to step 9:
15 goes into 100 6 times with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 39671.866
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.

After the division, we end up with 39671.866 and a remainder of 0.001.
