786872 divided by 15 
We're looking to find how many times 15 goes into 786872.

Going ahead to step 1:
15 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 15

Let's proceed to step 2:
78 divided by 15 is 5 with a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 75 from 78 to get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 15

Advancing to step 3:
15 goes into 36 2 times with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 52.0
If we subtract 30 from 36, we get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 15

Let's proceed to step 4:
If we divide 68 by 15, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 524.0
Deduct 60 from 68 and we're left with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 15

On to step 5:
87 divided by 15 is 5 with a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 5245.0
If we subtract 75 from 87, we get 12.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 15

Step 6:
If we divide 122 by 15, we get 8 and a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 52458.0
If we take 120 away from 122, 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.

Moving on to step 7:
The number 15 fits into 20 1 times, leaving a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 52458.1
If we subtract 15 from 20, 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 8:
15 goes into 50 3 times with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 52458.13
The remainder is 5 after subtracting 45 from 50.
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:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 52458.133
The remainder is 5 after subtracting 45 from 50.
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 52458.133 with a remaining 0.0005.
