We look at the division of 771894 by 86 
We're looking to find how many times 86 goes into 771894.

Let's proceed to step 1:
7 divided by 86 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 86

Advancing to step 2:
77 divided by 86 is 0 with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Bring next digit (1) of the dividend behind the 77 and repeat the process: 771 / 86

Let's proceed to step 3:
86 can be fit into 771 8 times, resulting in a remainder of 83.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 688 from 771, we get 83.
Append the next digit (8) from the dividend to 83 and continue with: 838 / 86

On to step 4:
When dividing 838 by 86, we get 9 with a remainder of 64.
Put 9 as the next digit of the answer. 
Result so far: 89.0
Subtracting 774 from 838 leaves us with 64.
Include the next digit (9) from the dividend after 64, then repeat: 649 / 86

Moving on to step 5:
When dividing 649 by 86, we get 7 with a remainder of 47.
Use 7 as the next digit of our solution. 
Result so far: 897.0
If we subtract 602 from 649, we get 47.
Take the next digit (4) from the dividend and append it to 47, then repeat: 474 / 86

Advancing to step 6:
86 goes into 474 5 times with a remainder of 44.
The number 5 becomes the next digit in our result. 
Result so far: 8975.0
Deduct 430 from 474 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 7:
If we divide 440 by 86, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 8975.5
Subtracting 430 from 440 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
100 divided by 86 is 1 with a remainder of 14.
The next digit of our result is 1. 
Result so far: 8975.51
Subtracting 86 from 100 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 9:
If we divide 140 by 86, we get 1 and a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 8975.511
Deduct 86 from 140 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

In conclusion, the division gives 8975.511 with a balance of 0.0054.
