802129 divided by 86 
Our goal is to divide 802129 by 86.

Step 1:
86 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 86

Moving on to step 2:
86 goes into 80 0 times with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Include the next digit (2) from the dividend after 80, then repeat: 802 / 86

Let's proceed to step 3:
When dividing 802 by 86, we get 9 with a remainder of 28.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 774 from 802 to get 28.
Bring next digit (1) of the dividend behind the 28 and repeat the process: 281 / 86

Let's proceed to step 4:
86 goes into 281 3 times with a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 93.0
If we take 258 away from 281, we end up with 23.
Take the next digit (2) from the dividend and append it to 23, then repeat: 232 / 86

Moving on to step 5:
When dividing 232 by 86, we get 2 with a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 932.0
The remainder is 60 after subtracting 172 from 232.
Append the next digit (9) from the dividend to 60 and continue with: 609 / 86

Moving on to step 6:
86 can be fit into 609 7 times, resulting in a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 9327.0
Subtract 602 from 609 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
70 divided by 86 is 0 with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 9327.0
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 8:
700 divided by 86 is 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 9327.08
Subtract 688 from 700 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.

Step 9:
If we divide 120 by 86, we get 1 and a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 9327.081
If we subtract 86 from 120, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 10:
86 can be fit into 340 3 times, resulting in a remainder of 82.
The next digit of our result is 3. 
Result so far: 9327.0813
Subtracting 258 from 340 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 11:
The number 86 fits into 820 9 times, leaving a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 9327.08139
The remainder is 46 after subtracting 774 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 12:
When dividing 460 by 86, we get 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 9327.081395
Subtract 430 from 460 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 13:
300 divided by 86 is 3 with a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 9327.0813953
Deduct 258 from 300 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 14:
86 goes into 420 4 times with a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 9327.08139534
Subtracting 344 from 420 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

In conclusion, the division gives 9327.08139534 with a balance of 7.6e-08.
