770485 ÷ 86 
Our goal is to divide 770485 by 86.

Step 1:
7 divided by 86 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 86

Moving on to step 2:
If we divide 77 by 86, we get 0 and a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Include the next digit (0) from the dividend after 77, then repeat: 770 / 86

Advancing to step 3:
When dividing 770 by 86, we get 8 with a remainder of 82.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 688 from 770, we get 82.
Include the next digit (4) from the dividend after 82, then repeat: 824 / 86

Step 4:
If we divide 824 by 86, we get 9 and a remainder of 50.
The next digit of our result is 9. 
Result so far: 89.0
If we take 774 away from 824, we end up with 50.
Bring next digit (8) of the dividend behind the 50 and repeat the process: 508 / 86

Advancing to step 5:
86 can be fit into 508 5 times, resulting in a remainder of 78.
The number 5 becomes the next digit in our result. 
Result so far: 895.0
If we subtract 430 from 508, we get 78.
Append the next digit (5) from the dividend to 78 and continue with: 785 / 86

Going ahead to step 6:
The number 86 fits into 785 9 times, leaving a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 8959.0
Subtract 774 from 785 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
The number 86 fits into 110 1 times, leaving a remainder of 24.
The next digit of our result is 1. 
Result so far: 8959.1
Subtracting 86 from 110 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 8:
When dividing 240 by 86, we get 2 with a remainder of 68.
The next digit of our result is 2. 
Result so far: 8959.12
The remainder is 68 after subtracting 172 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 9:
If we divide 680 by 86, we get 7 and a remainder of 78.
Use 7 as the next digit of our solution. 
Result so far: 8959.127
Subtracting 602 from 680 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 10:
If we divide 780 by 86, we get 9 and a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 8959.1279
If we take 774 away from 780, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
86 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 8959.1279
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 12:
86 goes into 600 6 times with a remainder of 84.
Put 6 as the next digit of the answer. 
Result so far: 8959.127906
Deduct 516 from 600 and we're left 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.

Moving on to step 13:
The number 86 fits into 840 9 times, leaving a remainder of 66.
The number 9 becomes the next digit in our result. 
Result so far: 8959.1279069
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.

Going ahead to step 14:
If we divide 660 by 86, we get 7 and a remainder of 58.
The next digit of our result is 7. 
Result so far: 8959.12790697
If we take 602 away from 660, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Our division results in 8959.12790697 with a remaining 5.8e-08.
