Let's divide 99853 by 15
Let's see how many times 15 fits into 99853.

Going ahead to step 1:
The number 15 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 15

Let's proceed to step 2:
When dividing 99 by 15, we get 6 with a remainder of 9.
The next digit of our result is 6. 
Result so far: 6.0
If we take 90 away from 99, we end up with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 15

Step 3:
If we divide 98 by 15, we get 6 and a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
Subtracting 90 from 98 leaves us with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 15

Going ahead to step 4:
When dividing 85 by 15, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 665.0
Subtract 75 from 85 to get 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 15

On to step 5:
When dividing 103 by 15, we get 6 with a remainder of 13.
Use 6 as the next digit of our solution. 
Result so far: 6656.0
Subtract 90 from 103 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 6:
The number 15 fits into 130 8 times, leaving a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 6656.8
If we take 120 away from 130, 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.

Step 7:
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: 6656.86
The remainder is 10 after subtracting 90 from 100.
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 8:
When dividing 100 by 15, we get 6 with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 6656.866
Subtracting 90 from 100 leaves us 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 outcome is 6656.866, with a leftover of 0.001.
