We divide 771909 by 86
Our goal is to divide 771909 by 86.

Step 1:
86 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 86

Moving on to step 2:
When dividing 77 by 86, we get 0 with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Include the next digit (1) from the dividend after 77, then repeat: 771 / 86

Moving on to step 3:
If we divide 771 by 86, we get 8 and a remainder of 83.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 688 away from 771, we end up with 83.
Include the next digit (9) from the dividend after 83, then repeat: 839 / 86

Advancing to step 4:
When dividing 839 by 86, we get 9 with a remainder of 65.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
The remainder is 65 after subtracting 774 from 839.
Append the next digit (0) from the dividend to 65 and continue with: 650 / 86

Let's proceed to step 5:
The number 86 fits into 650 7 times, leaving a remainder of 48.
Use 7 as the next digit of our solution. 
Result so far: 897.0
Subtracting 602 from 650 leaves us with 48.
Bring next digit (9) of the dividend behind the 48 and repeat the process: 489 / 86

Step 6:
If we divide 489 by 86, we get 5 and a remainder of 59.
Use 5 as the next digit of our solution. 
Result so far: 8975.0
The remainder is 59 after subtracting 430 from 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 7:
86 goes into 590 6 times with a remainder of 74.
Use 6 as the next digit of our solution. 
Result so far: 8975.6
If we subtract 516 from 590, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 8:
86 goes into 740 8 times with a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 8975.68
Deduct 688 from 740 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 9:
86 can be fit into 520 6 times, resulting in a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 8975.686
Deduct 516 from 520 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
40 divided by 86 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 8975.686
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
The number 86 fits into 400 4 times, leaving a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 8975.68604
Subtracting 344 from 400 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 12:
86 goes into 560 6 times with a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 8975.686046
If we take 516 away from 560, we end up 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 13:
If we divide 440 by 86, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 8975.6860465
Deduct 430 from 440 and we're left 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.

Moving on to step 14:
86 goes into 100 1 times with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 8975.68604651
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.

After the division, we end up with 8975.68604651 and a remainder of 1.4e-08.
