We're dividing 717308 by 86 
Let's see how many times 86 fits into 717308.

On to step 1:
If we divide 7 by 86, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 86

Step 2:
86 can be fit into 71 0 times, resulting in a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Grab the next digit (7) from the dividend, add it to 71, then carry on: 717 / 86

Step 3:
86 goes into 717 8 times with a remainder of 29.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 688 from 717 to get 29.
Bring next digit (3) of the dividend behind the 29 and repeat the process: 293 / 86

Let's proceed to step 4:
When dividing 293 by 86, we get 3 with a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 83.0
The remainder is 35 after subtracting 258 from 293.
Include the next digit (0) from the dividend after 35, then repeat: 350 / 86

Moving on to step 5:
86 goes into 350 4 times with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 834.0
The remainder is 6 after subtracting 344 from 350.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 86

Moving on to step 6:
68 divided by 86 is 0 with a remainder of 68.
The next digit of our result is 0. 
Result so far: 8340.0
The remainder is 68 after subtracting 0 from 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 7:
86 can be fit into 680 7 times, resulting in a remainder of 78.
Use 7 as the next digit of our solution. 
Result so far: 8340.7
If we take 602 away from 680, we end up 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 8:
When dividing 780 by 86, we get 9 with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 8340.79
The remainder is 6 after subtracting 774 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
When dividing 60 by 86, we get 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 8340.79
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 10:
600 divided by 86 is 6 with a remainder of 84.
Put 6 as the next digit of the answer. 
Result so far: 8340.7906
Subtract 516 from 600 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 11:
If we divide 840 by 86, we get 9 and a remainder of 66.
The next digit of our result is 9. 
Result so far: 8340.79069
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.

Moving on to step 12:
86 can be fit into 660 7 times, resulting in a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 8340.790697
Deduct 602 from 660 and we're left 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.

Let's proceed to step 13:
86 goes into 580 6 times with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 8340.7906976
Deduct 516 from 580 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 14:
If we divide 640 by 86, we get 7 and a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 8340.79069767
Deduct 602 from 640 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final outcome is 8340.79069767, with a leftover of 3.8e-08.
