Let's divide 830644 by 99
Let's see how many times 99 fits into 830644.

Moving on to step 1:
The number 99 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 99

On to step 2:
When dividing 83 by 99, we get 0 with a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 83, we end up with 83.
Grab the next digit (0) from the dividend, add it to 83, then carry on: 830 / 99

Let's proceed to step 3:
If we divide 830 by 99, we get 8 and a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 792 from 830 to get 38.
Append the next digit (6) from the dividend to 38 and continue with: 386 / 99

On to step 4:
386 divided by 99 is 3 with a remainder of 89.
The number 3 becomes the next digit in our result. 
Result so far: 83.0
If we take 297 away from 386, we end up with 89.
Grab the next digit (4) from the dividend, add it to 89, then carry on: 894 / 99

Step 5:
The number 99 fits into 894 9 times, leaving a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 839.0
Subtracting 891 from 894 leaves us with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 99

Moving on to step 6:
99 goes into 34 0 times with a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 8390.0
Subtracting 0 from 34 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 7:
If we divide 340 by 99, we get 3 and a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 8390.3
Subtract 297 from 340 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 8:
99 can be fit into 430 4 times, resulting in a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 8390.34
If we subtract 396 from 430, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 9:
The number 99 fits into 340 3 times, leaving a remainder of 43.
Record the quotient 3 as the next digit in the result. 
Result so far: 8390.343
If we take 297 away from 340, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 10:
430 divided by 99 is 4 with a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 8390.3434
Subtracting 396 from 430 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 11:
99 can be fit into 340 3 times, resulting in a remainder of 43.
Write down 3 as next digit of the result. 
Result so far: 8390.34343
The remainder is 43 after subtracting 297 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 12:
430 divided by 99 is 4 with a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 8390.343434
If we take 396 away from 430, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 13:
If we divide 340 by 99, we get 3 and a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 8390.3434343
The remainder is 43 after subtracting 297 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 14:
430 divided by 99 is 4 with a remainder of 34.
The next digit of our result is 4. 
Result so far: 8390.34343434
Subtract 396 from 430 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Our division results in 8390.34343434 with a remaining 3.4e-08.
