We're dividing 131121 by 50 
The aim is to understand the frequency of 50 in 131121.

Step 1:
50 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 50

Moving on to step 2:
The number 50 fits into 13 0 times, leaving a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 50

Going ahead to step 3:
131 divided by 50 is 2 with a remainder of 31.
The next digit of our result is 2. 
Result so far: 2.0
If we take 100 away from 131, we end up with 31.
Append the next digit (1) from the dividend to 31 and continue with: 311 / 50

Advancing to step 4:
311 divided by 50 is 6 with a remainder of 11.
The next digit of our result is 6. 
Result so far: 26.0
The remainder is 11 after subtracting 300 from 311.
Append the next digit (2) from the dividend to 11 and continue with: 112 / 50

Moving on to step 5:
The number 50 fits into 112 2 times, leaving a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 262.0
Subtract 100 from 112 to get 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 50

Advancing to step 6:
50 can be fit into 121 2 times, resulting in a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 2622.0
Subtracting 100 from 121 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 7:
50 can be fit into 210 4 times, resulting in a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 2622.4
Subtract 200 from 210 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
50 can be fit into 100 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2622.42
The remainder is 0 after subtracting 100 from 100.
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:
If we divide 0 by 50, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2622.42
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.

Let's proceed 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: 2622.42
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.

Our division results in 2622.42 with a remaining 0.0.
