We're dividing 686222 by 86 
Our goal is to divide 686222 by 86.

Advancing 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
If we subtract 0 from 6, we get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 86

Advancing to step 2:
The number 86 fits into 68 0 times, leaving a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Include the next digit (6) from the dividend after 68, then repeat: 686 / 86

Moving on to step 3:
When dividing 686 by 86, we get 7 with a remainder of 84.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 602 from 686 and we're left with 84.
Grab the next digit (2) from the dividend, add it to 84, then carry on: 842 / 86

Step 4:
86 goes into 842 9 times with a remainder of 68.
Write down 9 as next digit of the result. 
Result so far: 79.0
Subtracting 774 from 842 leaves us with 68.
Bring next digit (2) of the dividend behind the 68 and repeat the process: 682 / 86

Advancing to step 5:
86 can be fit into 682 7 times, resulting in a remainder of 80.
Put 7 as the next digit of the answer. 
Result so far: 797.0
Subtract 602 from 682 to get 80.
Grab the next digit (2) from the dividend, add it to 80, then carry on: 802 / 86

On to step 6:
802 divided by 86 is 9 with a remainder of 28.
Put 9 as the next digit of the answer. 
Result so far: 7979.0
If we subtract 774 from 802, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 7:
If we divide 280 by 86, we get 3 and a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 7979.3
If we take 258 away from 280, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 8:
86 can be fit into 220 2 times, resulting in a remainder of 48.
The next digit of our result is 2. 
Result so far: 7979.32
The remainder is 48 after subtracting 172 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 9:
When dividing 480 by 86, we get 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 7979.325
Deduct 430 from 480 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
The number 86 fits into 500 5 times, leaving a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 7979.3255
If we take 430 away from 500, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 7979.3255, with a leftover of 0.0007.
