We look at the division of 49636983 by 505 
The aim is to understand the frequency of 505 in 49636983.

Let's proceed to step 1:
When dividing 4 by 505, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 505

Moving on to step 2:
49 divided by 505 is 0 with a remainder of 49.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Grab the next digit (6) from the dividend, add it to 49, then carry on: 496 / 505

Step 3:
If we divide 496 by 505, we get 0 and a remainder of 496.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 496, we end up with 496.
Append the next digit (3) from the dividend to 496 and continue with: 4963 / 505

Moving on to step 4:
The number 505 fits into 4963 9 times, leaving a remainder of 418.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 4545 from 4963 to get 418.
Append the next digit (6) from the dividend to 418 and continue with: 4186 / 505

Moving on to step 5:
4186 divided by 505 is 8 with a remainder of 146.
Use 8 as the next digit of our solution. 
Result so far: 98.0
The remainder is 146 after subtracting 4040 from 4186.
Fetch the next digit (9) from the dividend, attach it to 146 and continue: 1469 / 505

On to step 6:
505 can be fit into 1469 2 times, resulting in a remainder of 459.
Write down 2 as next digit of the result. 
Result so far: 982.0
Deduct 1010 from 1469 and we're left with 459.
Bring next digit (8) of the dividend behind the 459 and repeat the process: 4598 / 505

Let's proceed to step 7:
505 goes into 4598 9 times with a remainder of 53.
Put 9 as the next digit of the answer. 
Result so far: 9829.0
If we take 4545 away from 4598, we end up with 53.
Bring next digit (3) of the dividend behind the 53 and repeat the process: 533 / 505

Let's proceed to step 8:
505 goes into 533 1 times with a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 98291.0
If we take 505 away from 533, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
If we divide 280 by 505, we get 0 and a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 98291.0
If we take 0 away from 280, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 10:
If we divide 2800 by 505, we get 5 and a remainder of 275.
Use 5 as the next digit of our solution. 
Result so far: 98291.05
Subtract 2525 from 2800 to get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Advancing to step 11:
505 can be fit into 2750 5 times, resulting in a remainder of 225.
Write down 5 as next digit of the result. 
Result so far: 98291.055
Subtract 2525 from 2750 to get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

The quotient of the division is 98291.055, and the remainder is 0.0225.
