686203 ÷ 84 
We want to figure out the number of times 686203 can be divided by 84.

Let's proceed to step 1:
84 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 84

Advancing to step 2:
When dividing 68 by 84, we get 0 with a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Bring next digit (6) of the dividend behind the 68 and repeat the process: 686 / 84

On to step 3:
84 can be fit into 686 8 times, resulting in a remainder of 14.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 14 after subtracting 672 from 686.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 84

Going ahead to step 4:
The number 84 fits into 142 1 times, leaving a remainder of 58.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
If we subtract 84 from 142, we get 58.
Fetch the next digit (0) from the dividend, attach it to 58 and continue: 580 / 84

Moving on to step 5:
When dividing 580 by 84, we get 6 with a remainder of 76.
Use 6 as the next digit of our solution. 
Result so far: 816.0
The remainder is 76 after subtracting 504 from 580.
Grab the next digit (3) from the dividend, add it to 76, then carry on: 763 / 84

On to step 6:
The number 84 fits into 763 9 times, leaving a remainder of 7.
The next digit of our result is 9. 
Result so far: 8169.0
Subtract 756 from 763 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
70 divided by 84 is 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 8169.0
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 8:
The number 84 fits into 700 8 times, leaving a remainder of 28.
The next digit of our result is 8. 
Result so far: 8169.08
If we take 672 away from 700, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
84 goes into 280 3 times with a remainder of 28.
The number 3 becomes the next digit in our result. 
Result so far: 8169.083
Subtracting 252 from 280 leaves us with 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 10:
When dividing 280 by 84, we get 3 with a remainder of 28.
Use 3 as the next digit of our solution. 
Result so far: 8169.0833
The remainder is 28 after subtracting 252 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 8169.0833 with a remainder of 0.00028.
