7887 divided by 15 
Let's see how many times 15 fits into 7887.

Step 1:
7 divided by 15 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 15

Advancing to step 2:
15 goes into 78 5 times with a remainder of 3.
The next digit of our result is 5. 
Result so far: 5.0
If we take 75 away from 78, we end up with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 15

Let's proceed to step 3:
15 can be fit into 38 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 52.0
If we take 30 away from 38, we end up with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 15

Moving on to step 4:
The number 15 fits into 87 5 times, leaving a remainder of 12.
The next digit of our result is 5. 
Result so far: 525.0
Subtract 75 from 87 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 5:
If we divide 120 by 15, we get 8 and a remainder of 0.
The next digit of our result is 8. 
Result so far: 525.8
If we take 120 away from 120, we end up 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.

Moving on to step 6:
The number 15 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 525.8
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
0 divided by 15 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 525.8
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 525.8, with a leftover of 0.0.
