849780 ÷ 50 
The aim is to understand the frequency of 50 in 849780.

Advancing 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.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 50

Moving on to step 2:
50 goes into 84 1 times with a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 50 from 84 and we're left with 34.
Include the next digit (9) from the dividend after 34, then repeat: 349 / 50

Going ahead to step 3:
The number 50 fits into 349 6 times, leaving a remainder of 49.
The next digit of our result is 6. 
Result so far: 16.0
Subtracting 300 from 349 leaves us with 49.
Take the next digit (7) from the dividend and append it to 49, then repeat: 497 / 50

Going ahead to step 4:
50 goes into 497 9 times with a remainder of 47.
Write down 9 as next digit of the result. 
Result so far: 169.0
Deduct 450 from 497 and we're left with 47.
Take the next digit (8) from the dividend and append it to 47, then repeat: 478 / 50

Let's proceed to step 5:
50 goes into 478 9 times with a remainder of 28.
Write down 9 as next digit of the result. 
Result so far: 1699.0
If we subtract 450 from 478, we get 28.
Take the next digit (0) from the dividend and append it to 28, then repeat: 280 / 50

Moving on to step 6:
280 divided by 50 is 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 16995.0
If we take 250 away from 280, 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.

On to step 7:
300 divided by 50 is 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 16995.6
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 8:
50 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 16995.6
Subtract 0 from 0 to 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.

Step 9:
0 divided by 50 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 16995.6
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 16995.6 with a remainder of 0.0.
