617435 ÷ 50 
The aim is to understand the frequency of 50 in 617435.

Going ahead to step 1:
50 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 50

On to step 2:
If we divide 61 by 50, we get 1 and a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 50 from 61, we get 11.
Include the next digit (7) from the dividend after 11, then repeat: 117 / 50

On to step 3:
The number 50 fits into 117 2 times, leaving a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 100 from 117, we get 17.
Include the next digit (4) from the dividend after 17, then repeat: 174 / 50

Let's proceed to step 4:
The number 50 fits into 174 3 times, leaving a remainder of 24.
The next digit of our result is 3. 
Result so far: 123.0
Subtract 150 from 174 to get 24.
Append the next digit (3) from the dividend to 24 and continue with: 243 / 50

Going ahead to step 5:
The number 50 fits into 243 4 times, leaving a remainder of 43.
Use 4 as the next digit of our solution. 
Result so far: 1234.0
Subtract 200 from 243 to get 43.
Grab the next digit (5) from the dividend, add it to 43, then carry on: 435 / 50

Advancing to step 6:
50 can be fit into 435 8 times, resulting in a remainder of 35.
Use 8 as the next digit of our solution. 
Result so far: 12348.0
If we take 400 away from 435, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 7:
When dividing 350 by 50, we get 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 12348.7
If we subtract 350 from 350, 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.

Going ahead to step 8:
50 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 12348.7
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.

Let's proceed to step 9:
50 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12348.7
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 12348.7 with a remainder of 0.0.
