We're dividing 100302 by 15 
We want to figure out the number of times 100302 can be divided by 15.

Let's proceed to step 1:
If we divide 1 by 15, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 15

Going ahead to step 2:
15 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 15

Step 3:
When dividing 100 by 15, we get 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 90 from 100 and we're left with 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 15

On to step 4:
When dividing 103 by 15, we get 6 with a remainder of 13.
Write down 6 as next digit of the result. 
Result so far: 66.0
If we subtract 90 from 103, we get 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 15

Moving on to step 5:
If we divide 130 by 15, we get 8 and a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 668.0
If we take 120 away from 130, we end up with 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 15

Going ahead to step 6:
If we divide 102 by 15, we get 6 and a remainder of 12.
The next digit of our result is 6. 
Result so far: 6686.0
Subtract 90 from 102 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 7:
15 can be fit into 120 8 times, resulting in a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 6686.8
The remainder is 0 after subtracting 120 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
The number 15 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6686.8
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
0 divided by 15 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6686.8
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 6686.8, with a leftover of 0.0.
