We look at the division of 553222 by 50 
The aim is to understand the frequency of 50 in 553222.

Advancing to step 1:
5 divided by 50 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 50

Step 2:
The number 50 fits into 55 1 times, leaving a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 5 after subtracting 50 from 55.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 50

On to step 3:
53 divided by 50 is 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtracting 50 from 53 leaves us with 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 50

Moving on to step 4:
32 divided by 50 is 0 with a remainder of 32.
Write down 0 as next digit of the result. 
Result so far: 110.0
If we subtract 0 from 32, we get 32.
Fetch the next digit (2) from the dividend, attach it to 32 and continue: 322 / 50

Advancing to step 5:
50 goes into 322 6 times with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 1106.0
Subtract 300 from 322 to get 22.
Grab the next digit (2) from the dividend, add it to 22, then carry on: 222 / 50

Let's proceed to step 6:
50 goes into 222 4 times with a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 11064.0
Subtracting 200 from 222 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
50 goes into 220 4 times with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 11064.4
If we subtract 200 from 220, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
If we divide 200 by 50, we get 4 and a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 11064.44
Subtracting 200 from 200 leaves us 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.

The final result is 11064.44 with a remainder of 0.0.
