509963 divided by 99 
We want to figure out the number of times 509963 can be divided by 99.

Going ahead to step 1:
The number 99 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 99

Moving on to step 2:
The number 99 fits into 50 0 times, leaving a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 50, we get 50.
Grab the next digit (9) from the dividend, add it to 50, then carry on: 509 / 99

Going ahead to step 3:
The number 99 fits into 509 5 times, leaving a remainder of 14.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 495 from 509 and we're left with 14.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 99

Going ahead to step 4:
99 can be fit into 149 1 times, resulting in a remainder of 50.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
If we take 99 away from 149, we end up with 50.
Take the next digit (6) from the dividend and append it to 50, then repeat: 506 / 99

On to step 5:
If we divide 506 by 99, we get 5 and a remainder of 11.
Record the quotient 5 as the next digit in the result. 
Result so far: 515.0
Deduct 495 from 506 and we're left with 11.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 99

Moving on to step 6:
113 divided by 99 is 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 5151.0
Deduct 99 from 113 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
If we divide 140 by 99, we get 1 and a remainder of 41.
Use 1 as the next digit of our solution. 
Result so far: 5151.1
Subtract 99 from 140 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 8:
If we divide 410 by 99, we get 4 and a remainder of 14.
The next digit of our result is 4. 
Result so far: 5151.14
Subtracting 396 from 410 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 9:
140 divided by 99 is 1 with a remainder of 41.
Record the quotient 1 as the next digit in the result. 
Result so far: 5151.141
If we subtract 99 from 140, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 10:
When dividing 410 by 99, we get 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 5151.1414
Deduct 396 from 410 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 11:
140 divided by 99 is 1 with a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 5151.14141
If we take 99 away from 140, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 12:
99 can be fit into 410 4 times, resulting in a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 5151.141414
Subtracting 396 from 410 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 13:
When dividing 140 by 99, we get 1 with a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 5151.1414141
If we take 99 away from 140, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 14:
The number 99 fits into 410 4 times, leaving a remainder of 14.
The next digit of our result is 4. 
Result so far: 5151.14141414
Subtracting 396 from 410 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 5151.14141414 and a remainder of 1.4e-08.
