83308222 ÷ 686 
Let's see how many times 686 fits into 83308222.

On to step 1:
The number 686 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 686

Step 2:
If we divide 83 by 686, we get 0 and a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Bring next digit (3) of the dividend behind the 83 and repeat the process: 833 / 686

Step 3:
If we divide 833 by 686, we get 1 and a remainder of 147.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 686 from 833 leaves us with 147.
Include the next digit (0) from the dividend after 147, then repeat: 1470 / 686

Advancing to step 4:
1470 divided by 686 is 2 with a remainder of 98.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 1372 from 1470 to get 98.
Append the next digit (8) from the dividend to 98 and continue with: 988 / 686

On to step 5:
988 divided by 686 is 1 with a remainder of 302.
Record the quotient 1 as the next digit in the result. 
Result so far: 121.0
Deduct 686 from 988 and we're left with 302.
Take the next digit (2) from the dividend and append it to 302, then repeat: 3022 / 686

On to step 6:
The number 686 fits into 3022 4 times, leaving a remainder of 278.
Use 4 as the next digit of our solution. 
Result so far: 1214.0
The remainder is 278 after subtracting 2744 from 3022.
Fetch the next digit (2) from the dividend, attach it to 278 and continue: 2782 / 686

Moving on to step 7:
The number 686 fits into 2782 4 times, leaving a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 12144.0
If we take 2744 away from 2782, we end up with 38.
Include the next digit (2) from the dividend after 38, then repeat: 382 / 686

Let's proceed to step 8:
The number 686 fits into 382 0 times, leaving a remainder of 382.
Put 0 as the next digit of the answer. 
Result so far: 121440.0
If we take 0 away from 382, we end up with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Going ahead to step 9:
686 goes into 3820 5 times with a remainder of 390.
Use 5 as the next digit of our solution. 
Result so far: 121440.5
Subtracting 3430 from 3820 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 10:
If we divide 3900 by 686, we get 5 and a remainder of 470.
The number 5 becomes the next digit in our result. 
Result so far: 121440.55
Deduct 3430 from 3900 and we're left with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

The final result is 121440.55 with a remainder of 0.47.
