517389 ÷ 99 
We're looking to find how many times 99 goes into 517389.

Going ahead to step 1:
When dividing 5 by 99, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 99

Moving on to step 2:
If we divide 51 by 99, we get 0 and a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Include the next digit (7) from the dividend after 51, then repeat: 517 / 99

Let's proceed to step 3:
517 divided by 99 is 5 with a remainder of 22.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 495 from 517 and we're left with 22.
Bring next digit (3) of the dividend behind the 22 and repeat the process: 223 / 99

On to step 4:
99 goes into 223 2 times with a remainder of 25.
Write down 2 as next digit of the result. 
Result so far: 52.0
The remainder is 25 after subtracting 198 from 223.
Take the next digit (8) from the dividend and append it to 25, then repeat: 258 / 99

Moving on to step 5:
The number 99 fits into 258 2 times, leaving a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 522.0
If we take 198 away from 258, we end up with 60.
Include the next digit (9) from the dividend after 60, then repeat: 609 / 99

Let's proceed to step 6:
99 goes into 609 6 times with a remainder of 15.
Put 6 as the next digit of the answer. 
Result so far: 5226.0
The remainder is 15 after subtracting 594 from 609.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
If we divide 150 by 99, we get 1 and a remainder of 51.
The number 1 becomes the next digit in our result. 
Result so far: 5226.1
If we subtract 99 from 150, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 8:
510 divided by 99 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 5226.15
Subtract 495 from 510 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 9:
99 can be fit into 150 1 times, resulting in a remainder of 51.
Record the quotient 1 as the next digit in the result. 
Result so far: 5226.151
The remainder is 51 after subtracting 99 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 10:
99 goes into 510 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 5226.1515
The remainder is 15 after subtracting 495 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 11:
99 goes into 150 1 times with a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 5226.15151
Deduct 99 from 150 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 12:
99 can be fit into 510 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 5226.151515
Deduct 495 from 510 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 13:
99 goes into 150 1 times with a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 5226.1515151
The remainder is 51 after subtracting 99 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 14:
When dividing 510 by 99, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 5226.15151515
If we take 495 away from 510, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 5226.15151515 and a remainder of 1.5e-08.
