We look at the division of 50420 by 99 
We want to figure out the number of times 50420 can be divided by 99.

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
Deduct 0 from 5 and we're left with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 99

Going ahead to step 2:
When dividing 50 by 99, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 50 leaves us with 50.
Fetch the next digit (4) from the dividend, attach it to 50 and continue: 504 / 99

Moving on to step 3:
If we divide 504 by 99, we get 5 and a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 495 from 504 and we're left with 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 99

Going ahead to step 4:
99 goes into 92 0 times with a remainder of 92.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
Deduct 0 from 92 and we're left with 92.
Grab the next digit (0) from the dividend, add it to 92, then carry on: 920 / 99

Moving on to step 5:
99 can be fit into 920 9 times, resulting in a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 509.0
Subtracting 891 from 920 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 6:
99 can be fit into 290 2 times, resulting in a remainder of 92.
Use 2 as the next digit of our solution. 
Result so far: 509.2
The remainder is 92 after subtracting 198 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 7:
If we divide 920 by 99, we get 9 and a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 509.29
The remainder is 29 after subtracting 891 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 8:
If we divide 290 by 99, we get 2 and a remainder of 92.
Write down 2 as next digit of the result. 
Result so far: 509.292
If we subtract 198 from 290, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 9:
99 can be fit into 920 9 times, resulting in a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 509.2929
Deduct 891 from 920 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 10:
99 goes into 290 2 times with a remainder of 92.
Use 2 as the next digit of our solution. 
Result so far: 509.29292
The remainder is 92 after subtracting 198 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 11:
If we divide 920 by 99, we get 9 and a remainder of 29.
The next digit of our result is 9. 
Result so far: 509.292929
If we take 891 away from 920, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 12:
290 divided by 99 is 2 with a remainder of 92.
Put 2 as the next digit of the answer. 
Result so far: 509.2929292
If we subtract 198 from 290, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 13:
The number 99 fits into 920 9 times, leaving a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 509.29292929
Deduct 891 from 920 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Our division results in 509.29292929 with a remaining 2.9e-08.
