We look at the division of 168102 by 15 
Let's see how many times 15 fits into 168102.

Moving on to step 1:
15 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 15

Let's proceed to step 2:
When dividing 16 by 15, we get 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 15 from 16, we get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 15

Moving on to step 3:
The number 15 fits into 18 1 times, leaving a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 15 from 18, we get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 15

Advancing to step 4:
15 can be fit into 31 2 times, resulting in a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 112.0
The remainder is 1 after subtracting 30 from 31.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 15

Going ahead to step 5:
10 divided by 15 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 1120.0
Subtracting 0 from 10 leaves us with 10.
Bring next digit (2) of the dividend behind the 10 and repeat the process: 102 / 15

Step 6:
102 divided by 15 is 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 11206.0
If we subtract 90 from 102, we 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.

On to step 7:
If we divide 120 by 15, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 11206.8
If we subtract 120 from 120, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
0 divided by 15 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 11206.8
Subtracting 0 from 0 leaves us 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.

Advancing to step 9:
The number 15 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 11206.8
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.

After the division, we end up with 11206.8 and a remainder of 0.0.
