We look at the division of 81029902 by 209 
We're looking to find how many times 209 goes into 81029902.

Going ahead to step 1:
When dividing 8 by 209, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 209

Moving on to step 2:
209 can be fit into 81 0 times, resulting in a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Bring next digit (0) of the dividend behind the 81 and repeat the process: 810 / 209

Advancing to step 3:
209 can be fit into 810 3 times, resulting in a remainder of 183.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 627 from 810 leaves us with 183.
Append the next digit (2) from the dividend to 183 and continue with: 1832 / 209

Let's proceed to step 4:
209 can be fit into 1832 8 times, resulting in a remainder of 160.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Subtract 1672 from 1832 to get 160.
Append the next digit (9) from the dividend to 160 and continue with: 1609 / 209

Moving on to step 5:
When dividing 1609 by 209, we get 7 with a remainder of 146.
Record the quotient 7 as the next digit in the result. 
Result so far: 387.0
Subtracting 1463 from 1609 leaves us with 146.
Bring next digit (9) of the dividend behind the 146 and repeat the process: 1469 / 209

Moving on to step 6:
1469 divided by 209 is 7 with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 3877.0
If we subtract 1463 from 1469, we get 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 209

Step 7:
60 divided by 209 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 38770.0
The remainder is 60 after subtracting 0 from 60.
Include the next digit (2) from the dividend after 60, then repeat: 602 / 209

Moving on to step 8:
The number 209 fits into 602 2 times, leaving a remainder of 184.
Use 2 as the next digit of our solution. 
Result so far: 387702.0
If we take 418 away from 602, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 9:
209 goes into 1840 8 times with a remainder of 168.
Put 8 as the next digit of the answer. 
Result so far: 387702.8
If we take 1672 away from 1840, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Step 10:
The number 209 fits into 1680 8 times, leaving a remainder of 8.
The next digit of our result is 8. 
Result so far: 387702.88
Subtracting 1672 from 1680 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 387702.88 with a balance of 0.008.
