940490 ÷ 50 
The aim is to understand the frequency of 50 in 940490.

Step 1:
The number 50 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 50

Moving on to step 2:
50 goes into 94 1 times with a remainder of 44.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 44 after subtracting 50 from 94.
Bring next digit (0) of the dividend behind the 44 and repeat the process: 440 / 50

Going ahead to step 3:
50 can be fit into 440 8 times, resulting in a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Deduct 400 from 440 and we're left with 40.
Append the next digit (4) from the dividend to 40 and continue with: 404 / 50

Step 4:
404 divided by 50 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 188.0
The remainder is 4 after subtracting 400 from 404.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 50

On to step 5:
50 goes into 49 0 times with a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 1880.0
Subtracting 0 from 49 leaves us with 49.
Append the next digit (0) from the dividend to 49 and continue with: 490 / 50

Let's proceed to step 6:
If we divide 490 by 50, we get 9 and a remainder of 40.
The number 9 becomes the next digit in our result. 
Result so far: 18809.0
Subtract 450 from 490 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 7:
50 goes into 400 8 times with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 18809.8
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.

Going ahead to step 8:
The number 50 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 18809.8
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.

Let's proceed to step 9:
50 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 18809.8
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.

The final result is 18809.8 with a remainder of 0.0.
