787599 ÷ 15 
Our goal is to divide 787599 by 15.

Advancing to step 1:
If we divide 7 by 15, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 15

Let's proceed to step 2:
78 divided by 15 is 5 with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 75 from 78, we get 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 15

Let's proceed to step 3:
When dividing 37 by 15, we get 2 with a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
Deduct 30 from 37 and we're left with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 15

Going ahead to step 4:
15 goes into 75 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 525.0
Deduct 75 from 75 and we're left with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 15

Going ahead to step 5:
9 divided by 15 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 5250.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 15

Step 6:
15 can be fit into 99 6 times, resulting in a remainder of 9.
The next digit of our result is 6. 
Result so far: 52506.0
If we take 90 away from 99, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
15 goes into 90 6 times with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 52506.6
Deduct 90 from 90 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
The number 15 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 52506.6
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
15 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 52506.6
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 52506.6 and a remainder of 0.0.
