We're dividing 852799 by 15 
Let's see how many times 15 fits into 852799.

Step 1:
8 divided by 15 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 15

Step 2:
The number 15 fits into 85 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 10 after subtracting 75 from 85.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 15

Let's proceed to step 3:
15 can be fit into 102 6 times, resulting in a remainder of 12.
The next digit of our result is 6. 
Result so far: 56.0
If we subtract 90 from 102, we get 12.
Take the next digit (7) from the dividend and append it to 12, then repeat: 127 / 15

Moving on to step 4:
When dividing 127 by 15, we get 8 with a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 568.0
Deduct 120 from 127 and we're left with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 15

Advancing to step 5:
79 divided by 15 is 5 with a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 5685.0
Deduct 75 from 79 and we're left with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 15

Going ahead to step 6:
15 can be fit into 49 3 times, resulting in a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 56853.0
If we take 45 away from 49, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
40 divided by 15 is 2 with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 56853.2
If we subtract 30 from 40, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead 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: 56853.26
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.

Let's proceed to step 9:
15 can be fit into 100 6 times, resulting in a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 56853.266
Deduct 90 from 100 and we're left 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.

The final result is 56853.266 with a remainder of 0.001.
