839366 ÷ 99 
Let's see how many times 99 fits into 839366.

Step 1:
8 divided by 99 is 0 with 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.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 99

Let's proceed to step 2:
99 can be fit into 83 0 times, resulting in a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Take the next digit (9) from the dividend and append it to 83, then repeat: 839 / 99

On to step 3:
The number 99 fits into 839 8 times, leaving a remainder of 47.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 47 after subtracting 792 from 839.
Include the next digit (3) from the dividend after 47, then repeat: 473 / 99

Advancing to step 4:
The number 99 fits into 473 4 times, leaving a remainder of 77.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
Subtract 396 from 473 to get 77.
Grab the next digit (6) from the dividend, add it to 77, then carry on: 776 / 99

Going ahead to step 5:
The number 99 fits into 776 7 times, leaving a remainder of 83.
The next digit of our result is 7. 
Result so far: 847.0
The remainder is 83 after subtracting 693 from 776.
Fetch the next digit (6) from the dividend, attach it to 83 and continue: 836 / 99

Going ahead to step 6:
The number 99 fits into 836 8 times, leaving a remainder of 44.
The next digit of our result is 8. 
Result so far: 8478.0
The remainder is 44 after subtracting 792 from 836.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 7:
The number 99 fits into 440 4 times, leaving a remainder of 44.
Put 4 as the next digit of the answer. 
Result so far: 8478.4
Subtracting 396 from 440 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 8:
99 can be fit into 440 4 times, resulting in a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 8478.44
If we take 396 away from 440, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

In conclusion, the division gives 8478.44 with a balance of 0.044.
