Let's divide 869852 by 15
We want to figure out the number of times 869852 can be divided by 15.

Advancing to step 1:
15 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 15

Advancing to step 2:
If we divide 86 by 15, we get 5 and a remainder of 11.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 75 from 86 leaves us with 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 15

Advancing to step 3:
15 goes into 119 7 times with a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 57.0
Subtract 105 from 119 to get 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 15

Moving on to step 4:
15 goes into 148 9 times with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 579.0
If we take 135 away from 148, we end up with 13.
Take the next digit (5) from the dividend and append it to 13, then repeat: 135 / 15

Moving on to step 5:
15 can be fit into 135 9 times, resulting in a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 5799.0
If we take 135 away from 135, we end up with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 15

Let's proceed to step 6:
15 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 57990.0
Subtracting 0 from 2 leaves us 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.

Let's proceed to step 7:
15 can be fit into 20 1 times, resulting in a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 57990.1
If we take 15 away from 20, we end up 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.

On to step 8:
50 divided by 15 is 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 57990.13
Subtract 45 from 50 to 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.

Going ahead to step 9:
50 divided by 15 is 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 57990.133
Subtract 45 from 50 to 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.

The quotient of the division is 57990.133, and the remainder is 0.0005.
