We're dividing 165102 by 15 
We want to figure out the number of times 165102 can be divided by 15.

Let's proceed to step 1:
15 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 15

Going ahead to step 2:
When dividing 16 by 15, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 15 away from 16, we end up with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 15

Let's proceed to step 3:
The number 15 fits into 15 1 times, leaving a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 15 from 15 and we're left with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 15

Advancing to step 4:
15 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 110.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 15

Step 5:
15 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 1100.0
Deduct 0 from 10 and we're left with 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 15

Moving on to step 6:
If we divide 102 by 15, we get 6 and a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 11006.0
Subtracting 90 from 102 leaves us with 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:
When dividing 120 by 15, we get 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 11006.8
Subtracting 120 from 120 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.

Moving on to step 8:
If we divide 0 by 15, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 11006.8
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.

On to step 9:
15 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 11006.8
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.

Our division results in 11006.8 with a remaining 0.0.
