Let's divide 663239 by 99
We're looking to find how many times 99 goes into 663239.

Step 1:
6 divided by 99 is 0 with 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.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 99

Step 2:
The number 99 fits into 66 0 times, leaving a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Fetch the next digit (3) from the dividend, attach it to 66 and continue: 663 / 99

Let's proceed to step 3:
If we divide 663 by 99, we get 6 and a remainder of 69.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 69 after subtracting 594 from 663.
Bring next digit (2) of the dividend behind the 69 and repeat the process: 692 / 99

Step 4:
692 divided by 99 is 6 with a remainder of 98.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
Deduct 594 from 692 and we're left with 98.
Include the next digit (3) from the dividend after 98, then repeat: 983 / 99

Let's proceed to step 5:
983 divided by 99 is 9 with a remainder of 92.
Put 9 as the next digit of the answer. 
Result so far: 669.0
Subtracting 891 from 983 leaves us with 92.
Take the next digit (9) from the dividend and append it to 92, then repeat: 929 / 99

Moving on to step 6:
99 can be fit into 929 9 times, resulting in a remainder of 38.
The next digit of our result is 9. 
Result so far: 6699.0
Deduct 891 from 929 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 7:
99 goes into 380 3 times with a remainder of 83.
Use 3 as the next digit of our solution. 
Result so far: 6699.3
If we take 297 away from 380, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 8:
99 can be fit into 830 8 times, resulting in a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 6699.38
If we subtract 792 from 830, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 9:
99 can be fit into 380 3 times, resulting in a remainder of 83.
The number 3 becomes the next digit in our result. 
Result so far: 6699.383
Subtracting 297 from 380 leaves us with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 10:
99 can be fit into 830 8 times, resulting in a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 6699.3838
Subtract 792 from 830 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 11:
99 goes into 380 3 times with a remainder of 83.
The next digit of our result is 3. 
Result so far: 6699.38383
If we take 297 away from 380, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Moving on to step 12:
99 can be fit into 830 8 times, resulting in a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 6699.383838
Subtracting 792 from 830 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 13:
The number 99 fits into 380 3 times, leaving a remainder of 83.
The number 3 becomes the next digit in our result. 
Result so far: 6699.3838383
If we subtract 297 from 380, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 14:
99 can be fit into 830 8 times, resulting in a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 6699.38383838
If we subtract 792 from 830, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Our division results in 6699.38383838 with a remaining 3.8e-08.
