We look at the division of 490808 by 50 
The aim is to understand the frequency of 50 in 490808.

Let's proceed to step 1:
The number 50 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 50

On to step 2:
49 divided by 50 is 0 with a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 49, we end up with 49.
Bring next digit (0) of the dividend behind the 49 and repeat the process: 490 / 50

On to step 3:
490 divided by 50 is 9 with a remainder of 40.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 450 from 490 leaves us with 40.
Grab the next digit (8) from the dividend, add it to 40, then carry on: 408 / 50

Let's proceed to step 4:
If we divide 408 by 50, we get 8 and a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
Subtract 400 from 408 to get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 50

On to step 5:
50 can be fit into 80 1 times, resulting in a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 981.0
If we take 50 away from 80, we end up with 30.
Take the next digit (8) from the dividend and append it to 30, then repeat: 308 / 50

Advancing to step 6:
If we divide 308 by 50, we get 6 and a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 9816.0
If we subtract 300 from 308, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
50 goes into 80 1 times with a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 9816.1
Subtracting 50 from 80 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
The number 50 fits into 300 6 times, leaving a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 9816.16
If we take 300 away from 300, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
When dividing 0 by 50, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9816.16
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
The number 50 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 9816.16
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 9816.16 with a remainder of 0.0.
