201980 ÷ 50 
The aim is to understand the frequency of 50 in 201980.

Let's proceed to step 1:
50 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 50

Let's proceed to step 2:
If we divide 20 by 50, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 50

Advancing to step 3:
When dividing 201 by 50, we get 4 with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 200 from 201, we get 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 50

Advancing to step 4:
50 goes into 19 0 times with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Subtracting 0 from 19 leaves us with 19.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 50

Step 5:
When dividing 198 by 50, we get 3 with a remainder of 48.
The next digit of our result is 3. 
Result so far: 403.0
Subtract 150 from 198 to get 48.
Bring next digit (0) of the dividend behind the 48 and repeat the process: 480 / 50

Let's proceed to step 6:
If we divide 480 by 50, we get 9 and a remainder of 30.
Write down 9 as next digit of the result. 
Result so far: 4039.0
If we take 450 away from 480, 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.

Advancing to step 7:
If we divide 300 by 50, we get 6 and a remainder of 0.
The next digit of our result is 6. 
Result so far: 4039.6
Deduct 300 from 300 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.

Step 8:
50 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4039.6
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.

Moving on 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: 4039.6
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.

The final result is 4039.6 with a remainder of 0.0.
