We look at the division of 684946 by 86 
Let's see how many times 86 fits into 684946.

Advancing to step 1:
If we divide 6 by 86, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 86

Advancing to step 2:
86 goes into 68 0 times with a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Take the next digit (4) from the dividend and append it to 68, then repeat: 684 / 86

Advancing to step 3:
86 goes into 684 7 times with a remainder of 82.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 602 away from 684, we end up with 82.
Grab the next digit (9) from the dividend, add it to 82, then carry on: 829 / 86

Advancing to step 4:
829 divided by 86 is 9 with a remainder of 55.
The number 9 becomes the next digit in our result. 
Result so far: 79.0
The remainder is 55 after subtracting 774 from 829.
Grab the next digit (4) from the dividend, add it to 55, then carry on: 554 / 86

Let's proceed to step 5:
When dividing 554 by 86, we get 6 with a remainder of 38.
The number 6 becomes the next digit in our result. 
Result so far: 796.0
Deduct 516 from 554 and we're left with 38.
Append the next digit (6) from the dividend to 38 and continue with: 386 / 86

Let's proceed to step 6:
386 divided by 86 is 4 with a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 7964.0
Subtracting 344 from 386 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 7:
If we divide 420 by 86, we get 4 and a remainder of 76.
The next digit of our result is 4. 
Result so far: 7964.4
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.

Going ahead to step 8:
86 goes into 760 8 times with a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 7964.48
The remainder is 72 after subtracting 688 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 9:
When dividing 720 by 86, we get 8 with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 7964.488
The remainder is 32 after subtracting 688 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 7964.488 with a remainder of 0.0032.
