907877 divided by 15 
We're looking to find how many times 15 goes into 907877.

Step 1:
9 divided by 15 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 15

Moving on to step 2:
15 can be fit into 90 6 times, resulting in a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 90 from 90 leaves us with 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 15

On to step 3:
7 divided by 15 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 60.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 15

Going ahead to step 4:
The number 15 fits into 78 5 times, leaving a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 605.0
Deduct 75 from 78 and we're left with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 15

Going ahead to step 5:
15 goes into 37 2 times with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 6052.0
Subtract 30 from 37 to get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 15

Going ahead to step 6:
77 divided by 15 is 5 with a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 60525.0
If we take 75 away from 77, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
The number 15 fits into 20 1 times, leaving a remainder of 5.
The next digit of our result is 1. 
Result so far: 60525.1
Deduct 15 from 20 and we're left 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.

Let's proceed to step 8:
If we divide 50 by 15, we get 3 and a remainder of 5.
The next digit of our result is 3. 
Result so far: 60525.13
If we subtract 45 from 50, 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 9:
50 divided by 15 is 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 60525.133
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 60525.133 with a remaining 0.0005.
