490190 ÷ 50 
The aim is to understand the frequency of 50 in 490190.

Advancing to step 1:
When dividing 4 by 50, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 50

Going ahead to step 2:
When dividing 49 by 50, we get 0 with a remainder of 49.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 49 and we're left with 49.
Bring next digit (0) of the dividend behind the 49 and repeat the process: 490 / 50

Let's proceed to step 3:
50 goes into 490 9 times with a remainder of 40.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 450 from 490, we get 40.
Include the next digit (1) from the dividend after 40, then repeat: 401 / 50

Advancing to step 4:
The number 50 fits into 401 8 times, leaving a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 98.0
If we subtract 400 from 401, we get 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 50

Advancing to step 5:
50 goes into 19 0 times with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 980.0
Subtracting 0 from 19 leaves us with 19.
Take the next digit (0) from the dividend and append it to 19, then repeat: 190 / 50

Advancing to step 6:
50 goes into 190 3 times with a remainder of 40.
Write down 3 as next digit of the result. 
Result so far: 9803.0
Subtract 150 from 190 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.

On to step 7:
If we divide 400 by 50, we get 8 and a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 9803.8
The remainder is 0 after subtracting 400 from 400.
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:
If we divide 0 by 50, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 9803.8
If we take 0 away from 0, we end up 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:
The number 50 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9803.8
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 quotient of the division is 9803.8, and the remainder is 0.0.
