We look at the division of 578791 by 85 
We want to divide 578791 by 85.

Moving on to step 1:
When dividing 5 by 85, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 85

Step 2:
When dividing 57 by 85, we get 0 with a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 57 after subtracting 0 from 57.
Bring next digit (8) of the dividend behind the 57 and repeat the process: 578 / 85

On to step 3:
85 can be fit into 578 6 times, resulting in a remainder of 68.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 510 from 578 and we're left with 68.
Bring next digit (7) of the dividend behind the 68 and repeat the process: 687 / 85

Going ahead to step 4:
687 divided by 85 is 8 with a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 68.0
Subtracting 680 from 687 leaves us with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 85

Let's proceed to step 5:
The number 85 fits into 79 0 times, leaving a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 680.0
If we subtract 0 from 79, we get 79.
Fetch the next digit (1) from the dividend, attach it to 79 and continue: 791 / 85

Step 6:
When dividing 791 by 85, we get 9 with a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 6809.0
Subtract 765 from 791 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 7:
If we divide 260 by 85, we get 3 and a remainder of 5.
The next digit of our result is 3. 
Result so far: 6809.3
Deduct 255 from 260 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.

Let's proceed to step 8:
85 can be fit into 50 0 times, resulting in a remainder of 50.
The next digit of our result is 0. 
Result so far: 6809.3
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 9:
85 can be fit into 500 5 times, resulting in a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 6809.305
Subtract 425 from 500 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 10:
If we divide 750 by 85, we get 8 and a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 6809.3058
Deduct 680 from 750 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.

Step 11:
If we divide 700 by 85, we get 8 and a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 6809.30588
If we take 680 away from 700, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 6809.30588 with a balance of 2e-05.
