We look at the division of 684168 by 86 
Our goal is to divide 684168 by 86.

Advancing to step 1:
When dividing 6 by 86, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 86

Step 2:
If we divide 68 by 86, we get 0 and a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Bring next digit (4) of the dividend behind the 68 and repeat the process: 684 / 86

On to step 3:
86 goes into 684 7 times with a remainder of 82.
The next digit of our result is 7. 
Result so far: 7.0
If we take 602 away from 684, we end up with 82.
Fetch the next digit (1) from the dividend, attach it to 82 and continue: 821 / 86

Going ahead to step 4:
821 divided by 86 is 9 with a remainder of 47.
The next digit of our result is 9. 
Result so far: 79.0
Subtracting 774 from 821 leaves us with 47.
Append the next digit (6) from the dividend to 47 and continue with: 476 / 86

On to step 5:
476 divided by 86 is 5 with a remainder of 46.
The number 5 becomes the next digit in our result. 
Result so far: 795.0
If we subtract 430 from 476, we get 46.
Fetch the next digit (8) from the dividend, attach it to 46 and continue: 468 / 86

Moving on to step 6:
The number 86 fits into 468 5 times, leaving a remainder of 38.
The next digit of our result is 5. 
Result so far: 7955.0
The remainder is 38 after subtracting 430 from 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 7:
380 divided by 86 is 4 with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 7955.4
The remainder is 36 after subtracting 344 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 8:
The number 86 fits into 360 4 times, leaving a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 7955.44
Subtract 344 from 360 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 7955.44 with a remaining 0.016.
