809703 ÷ 50 
The aim is to understand the frequency of 50 in 809703.

Moving on to step 1:
If we divide 8 by 50, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 50

Step 2:
When dividing 80 by 50, we get 1 with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 50 from 80 to get 30.
Take the next digit (9) from the dividend and append it to 30, then repeat: 309 / 50

Going ahead to step 3:
When dividing 309 by 50, we get 6 with a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtract 300 from 309 to get 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 50

Let's proceed to step 4:
If we divide 97 by 50, we get 1 and a remainder of 47.
The number 1 becomes the next digit in our result. 
Result so far: 161.0
If we subtract 50 from 97, we get 47.
Append the next digit (0) from the dividend to 47 and continue with: 470 / 50

On to step 5:
50 can be fit into 470 9 times, resulting in a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 1619.0
The remainder is 20 after subtracting 450 from 470.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 50

Going ahead to step 6:
If we divide 203 by 50, we get 4 and a remainder of 3.
The next digit of our result is 4. 
Result so far: 16194.0
The remainder is 3 after subtracting 200 from 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
50 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 16194.0
If we take 0 away from 30, we end up 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.

Going ahead to step 8:
When dividing 300 by 50, we get 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 16194.06
Subtracting 300 from 300 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.

Advancing to step 9:
The number 50 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 16194.06
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.

Going ahead to step 10:
50 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 16194.06
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.

After the division, we end up with 16194.06 and a remainder of 0.0.
