802859 ÷ 86 
Let's see how many times 86 fits into 802859.

Going ahead to step 1:
When dividing 8 by 86, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 86

Step 2:
If we divide 80 by 86, we get 0 and 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.
Bring next digit (2) of the dividend behind the 80 and repeat the process: 802 / 86

Advancing to step 3:
If we divide 802 by 86, we get 9 and a remainder of 28.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 774 from 802 leaves us with 28.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 86

Step 4:
The number 86 fits into 288 3 times, leaving a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 93.0
The remainder is 30 after subtracting 258 from 288.
Grab the next digit (5) from the dividend, add it to 30, then carry on: 305 / 86

On to step 5:
86 goes into 305 3 times with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 933.0
Deduct 258 from 305 and we're left with 47.
Fetch the next digit (9) from the dividend, attach it to 47 and continue: 479 / 86

Step 6:
When dividing 479 by 86, we get 5 with a remainder of 49.
The next digit of our result is 5. 
Result so far: 9335.0
Subtract 430 from 479 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 7:
86 can be fit into 490 5 times, resulting in a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 9335.5
Subtract 430 from 490 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
The number 86 fits into 600 6 times, leaving a remainder of 84.
Record the quotient 6 as the next digit in the result. 
Result so far: 9335.56
Subtracting 516 from 600 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 9:
The number 86 fits into 840 9 times, leaving a remainder of 66.
Put 9 as the next digit of the answer. 
Result so far: 9335.569
The remainder is 66 after subtracting 774 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 10:
86 can be fit into 660 7 times, resulting in a remainder of 58.
Put 7 as the next digit of the answer. 
Result so far: 9335.5697
The remainder is 58 after subtracting 602 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 11:
If we divide 580 by 86, we get 6 and a remainder of 64.
The next digit of our result is 6. 
Result so far: 9335.56976
Subtracting 516 from 580 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 12:
86 can be fit into 640 7 times, resulting in a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 9335.569767
If we subtract 602 from 640, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 13:
86 can be fit into 380 4 times, resulting in a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 9335.5697674
If we subtract 344 from 380, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 14:
360 divided by 86 is 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 9335.56976744
If we take 344 away from 360, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 9335.56976744 with a balance of 1.6e-08.
