We divide 539450 by 50
The aim is to understand the frequency of 50 in 539450.

Step 1:
5 divided by 50 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 50

Step 2:
50 can be fit into 53 1 times, resulting in a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 50 away from 53, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 50

Advancing to step 3:
50 goes into 39 0 times with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 39 to get 39.
Append the next digit (4) from the dividend to 39 and continue with: 394 / 50

On to step 4:
394 divided by 50 is 7 with a remainder of 44.
Use 7 as the next digit of our solution. 
Result so far: 107.0
If we take 350 away from 394, we end up with 44.
Take the next digit (5) from the dividend and append it to 44, then repeat: 445 / 50

Advancing to step 5:
If we divide 445 by 50, we get 8 and a remainder of 45.
The number 8 becomes the next digit in our result. 
Result so far: 1078.0
The remainder is 45 after subtracting 400 from 445.
Grab the next digit (0) from the dividend, add it to 45, then carry on: 450 / 50

Advancing to step 6:
50 can be fit into 450 9 times, resulting in a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 10789.0
The remainder is 0 after subtracting 450 from 450.
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 7:
When dividing 0 by 50, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10789.0
If we take 0 away from 0, 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 8:
When dividing 0 by 50, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10789.0
Subtracting 0 from 0 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 10789.0 with a remainder of 0.0.
