679888 ÷ 86 
We want to figure out the number of times 679888 can be divided by 86.

Going ahead to step 1:
86 goes into 6 0 times with 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.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 86

Let's proceed to step 2:
86 can be fit into 67 0 times, resulting in a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 67, we end up with 67.
Grab the next digit (9) from the dividend, add it to 67, then carry on: 679 / 86

Step 3:
86 can be fit into 679 7 times, resulting in a remainder of 77.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 602 from 679 leaves us with 77.
Include the next digit (8) from the dividend after 77, then repeat: 778 / 86

Moving on to step 4:
86 goes into 778 9 times with a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 79.0
Subtract 774 from 778 to get 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 86

Advancing to step 5:
48 divided by 86 is 0 with a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 790.0
If we take 0 away from 48, we end up with 48.
Take the next digit (8) from the dividend and append it to 48, then repeat: 488 / 86

Step 6:
488 divided by 86 is 5 with a remainder of 58.
The next digit of our result is 5. 
Result so far: 7905.0
If we subtract 430 from 488, we get 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 7:
If we divide 580 by 86, we get 6 and a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 7905.6
If we take 516 away from 580, we end up 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.

Advancing to step 8:
86 goes into 640 7 times with a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 7905.67
If we subtract 602 from 640, we get 38.
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 9:
When dividing 380 by 86, we get 4 with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 7905.674
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.

On to step 10:
If we divide 360 by 86, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 7905.6744
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.

The final outcome is 7905.6744, with a leftover of 0.00016.
