We're dividing 770266 by 86 
We want to figure out the number of times 770266 can be divided by 86.

Step 1:
7 divided by 86 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 86

Let's proceed to step 2:
When dividing 77 by 86, we get 0 with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Grab the next digit (0) from the dividend, add it to 77, then carry on: 770 / 86

Advancing to step 3:
86 goes into 770 8 times with a remainder of 82.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 688 from 770 leaves us with 82.
Fetch the next digit (2) from the dividend, attach it to 82 and continue: 822 / 86

Moving on to step 4:
The number 86 fits into 822 9 times, leaving a remainder of 48.
Record the quotient 9 as the next digit in the result. 
Result so far: 89.0
The remainder is 48 after subtracting 774 from 822.
Bring next digit (6) of the dividend behind the 48 and repeat the process: 486 / 86

Let's proceed to step 5:
When dividing 486 by 86, we get 5 with a remainder of 56.
The next digit of our result is 5. 
Result so far: 895.0
If we subtract 430 from 486, we get 56.
Bring next digit (6) of the dividend behind the 56 and repeat the process: 566 / 86

Advancing to step 6:
566 divided by 86 is 6 with a remainder of 50.
Use 6 as the next digit of our solution. 
Result so far: 8956.0
Subtract 516 from 566 to 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.

Going ahead to step 7:
The number 86 fits into 500 5 times, leaving a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 8956.5
If we subtract 430 from 500, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 8:
700 divided by 86 is 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 8956.58
Deduct 688 from 700 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
When dividing 120 by 86, we get 1 with a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 8956.581
Subtract 86 from 120 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 10:
340 divided by 86 is 3 with a remainder of 82.
The next digit of our result is 3. 
Result so far: 8956.5813
Subtract 258 from 340 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 11:
86 can be fit into 820 9 times, resulting in a remainder of 46.
The next digit of our result is 9. 
Result so far: 8956.58139
If we subtract 774 from 820, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 12:
460 divided by 86 is 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 8956.581395
If we subtract 430 from 460, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 13:
When dividing 300 by 86, we get 3 with a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 8956.5813953
Subtract 258 from 300 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 14:
86 goes into 420 4 times with a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 8956.58139534
Subtract 344 from 420 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

After the division, we end up with 8956.58139534 and a remainder of 7.6e-08.
