686433 ÷ 99 
We're looking to find how many times 99 goes into 686433.

Moving on to step 1:
The number 99 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
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 / 99

Advancing to step 2:
The number 99 fits into 68 0 times, leaving a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Take the next digit (6) from the dividend and append it to 68, then repeat: 686 / 99

On to step 3:
If we divide 686 by 99, we get 6 and a remainder of 92.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 594 from 686 and we're left with 92.
Include the next digit (4) from the dividend after 92, then repeat: 924 / 99

Going ahead to step 4:
99 can be fit into 924 9 times, resulting in a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 69.0
Deduct 891 from 924 and we're left with 33.
Append the next digit (3) from the dividend to 33 and continue with: 333 / 99

On to step 5:
When dividing 333 by 99, we get 3 with a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 693.0
Subtract 297 from 333 to get 36.
Grab the next digit (3) from the dividend, add it to 36, then carry on: 363 / 99

Moving on to step 6:
363 divided by 99 is 3 with a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 6933.0
Deduct 297 from 363 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 7:
660 divided by 99 is 6 with a remainder of 66.
Write down 6 as next digit of the result. 
Result so far: 6933.6
The remainder is 66 after subtracting 594 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 8:
660 divided by 99 is 6 with a remainder of 66.
Record the quotient 6 as the next digit in the result. 
Result so far: 6933.66
If we subtract 594 from 660, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

After the division, we end up with 6933.66 and a remainder of 0.066.
