507590 ÷ 50 
The aim is to understand the frequency of 50 in 507590.

Let's proceed to step 1:
The number 50 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 50

Moving on to step 2:
The number 50 fits into 50 1 times, leaving a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 50 away from 50, we end up with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 50

On to step 3:
The number 50 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 50

Going ahead to step 4:
75 divided by 50 is 1 with a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 101.0
Deduct 50 from 75 and we're left with 25.
Include the next digit (9) from the dividend after 25, then repeat: 259 / 50

On to step 5:
When dividing 259 by 50, we get 5 with a remainder of 9.
The next digit of our result is 5. 
Result so far: 1015.0
The remainder is 9 after subtracting 250 from 259.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 50

Moving on to step 6:
If we divide 90 by 50, we get 1 and a remainder of 40.
Record the quotient 1 as the next digit in the result. 
Result so far: 10151.0
The remainder is 40 after subtracting 50 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 7:
When dividing 400 by 50, we get 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 10151.8
Subtracting 400 from 400 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.

Step 8:
50 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10151.8
Deduct 0 from 0 and we're left 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.

Step 9:
When dividing 0 by 50, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10151.8
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.

The final result is 10151.8 with a remainder of 0.0.
