We divide 679808 by 86
We're looking to find how many times 86 goes into 679808.

Advancing to step 1:
If we divide 6 by 86, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 86

On to step 2:
If we divide 67 by 86, we get 0 and a remainder of 67.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 67 and we're left with 67.
Grab the next digit (9) from the dividend, add it to 67, then carry on: 679 / 86

Let's proceed to step 3:
679 divided by 86 is 7 with a remainder of 77.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 602 from 679 to get 77.
Take the next digit (8) from the dividend and append it to 77, then repeat: 778 / 86

On to step 4:
If we divide 778 by 86, we get 9 and a remainder of 4.
The next digit of our result is 9. 
Result so far: 79.0
Deduct 774 from 778 and we're left with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 86

Step 5:
The number 86 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 790.0
Subtracting 0 from 40 leaves us with 40.
Bring next digit (8) of the dividend behind the 40 and repeat the process: 408 / 86

Going ahead to step 6:
If we divide 408 by 86, we get 4 and a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 7904.0
Subtracting 344 from 408 leaves us 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 7:
If we divide 640 by 86, we get 7 and a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 7904.7
Subtracting 602 from 640 leaves us 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.

Going ahead to step 8:
86 goes into 380 4 times with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 7904.74
If we subtract 344 from 380, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
If we divide 360 by 86, we get 4 and a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 7904.744
If we take 344 away from 360, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 7904.744, with a leftover of 0.0016.
