We divide 521909 by 99
Let's see how many times 99 fits into 521909.

Going ahead to step 1:
The number 99 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 99

Let's proceed to step 2:
99 goes into 52 0 times with a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Take the next digit (1) from the dividend and append it to 52, then repeat: 521 / 99

Let's proceed to step 3:
When dividing 521 by 99, we get 5 with a remainder of 26.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 495 from 521 to get 26.
Grab the next digit (9) from the dividend, add it to 26, then carry on: 269 / 99

Step 4:
99 goes into 269 2 times with a remainder of 71.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
Deduct 198 from 269 and we're left with 71.
Bring next digit (0) of the dividend behind the 71 and repeat the process: 710 / 99

Moving on to step 5:
99 goes into 710 7 times with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 527.0
The remainder is 17 after subtracting 693 from 710.
Take the next digit (9) from the dividend and append it to 17, then repeat: 179 / 99

Going ahead to step 6:
99 goes into 179 1 times with a remainder of 80.
Record the quotient 1 as the next digit in the result. 
Result so far: 5271.0
Deduct 99 from 179 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 7:
When dividing 800 by 99, we get 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 5271.8
Subtracting 792 from 800 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
The number 99 fits into 80 0 times, leaving a remainder of 80.
The next digit of our result is 0. 
Result so far: 5271.8
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 9:
When dividing 800 by 99, we get 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 5271.808
If we take 792 away from 800, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
The number 99 fits into 80 0 times, leaving a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 5271.808
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 11:
If we divide 800 by 99, we get 8 and a remainder of 8.
The next digit of our result is 8. 
Result so far: 5271.80808
The remainder is 8 after subtracting 792 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 12:
When dividing 80 by 99, we get 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 5271.80808
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 13:
When dividing 800 by 99, we get 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 5271.8080808
If we take 792 away from 800, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 14:
99 can be fit into 80 0 times, resulting in a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 5271.8080808
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

After the division, we end up with 5271.8080808 and a remainder of 8e-08.
