We're dividing 863509 by 68 
We're looking to find how many times 68 goes into 863509.

Step 1:
68 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 68

Step 2:
If we divide 86 by 68, we get 1 and a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 68 from 86, we get 18.
Fetch the next digit (3) from the dividend, attach it to 18 and continue: 183 / 68

On to step 3:
When dividing 183 by 68, we get 2 with a remainder of 47.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 47 after subtracting 136 from 183.
Include the next digit (5) from the dividend after 47, then repeat: 475 / 68

Moving on to step 4:
475 divided by 68 is 6 with a remainder of 67.
Record the quotient 6 as the next digit in the result. 
Result so far: 126.0
Subtract 408 from 475 to get 67.
Include the next digit (0) from the dividend after 67, then repeat: 670 / 68

On to step 5:
When dividing 670 by 68, we get 9 with a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 1269.0
If we take 612 away from 670, we end up with 58.
Take the next digit (9) from the dividend and append it to 58, then repeat: 589 / 68

Step 6:
When dividing 589 by 68, we get 8 with a remainder of 45.
The next digit of our result is 8. 
Result so far: 12698.0
The remainder is 45 after subtracting 544 from 589.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 7:
The number 68 fits into 450 6 times, leaving a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 12698.6
If we subtract 408 from 450, we 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.

Going ahead to step 8:
When dividing 420 by 68, we get 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 12698.66
If we take 408 away from 420, we end up 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.

Our division results in 12698.66 with a remaining 0.012.
