Let's divide 102110 by 15
We want to figure out the number of times 102110 can be divided by 15.

Step 1:
When dividing 1 by 15, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 15

Advancing 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 (2) from the dividend after 10, then repeat: 102 / 15

Going ahead to step 3:
102 divided by 15 is 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 90 from 102 and we're left with 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 15

On to step 4:
When dividing 121 by 15, we get 8 with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 68.0
Subtracting 120 from 121 leaves us with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 15

Moving on to step 5:
The number 15 fits into 11 0 times, leaving a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 680.0
If we subtract 0 from 11, we get 11.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 15

Let's proceed to step 6:
110 divided by 15 is 7 with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 6807.0
Subtract 105 from 110 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.

On to step 7:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 6807.3
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 8:
If we divide 50 by 15, we get 3 and a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 6807.33
Deduct 45 from 50 and we're left 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.

In conclusion, the division gives 6807.33 with a balance of 0.005.
