We divide 13090 by 50
The aim is to understand the frequency of 50 in 13090.

Step 1:
1 divided by 50 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 50

Step 2:
When dividing 13 by 50, we get 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 50

Step 3:
130 divided by 50 is 2 with a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 100 from 130 to get 30.
Take the next digit (9) from the dividend and append it to 30, then repeat: 309 / 50

Moving on to step 4:
50 goes into 309 6 times with a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
Subtract 300 from 309 to get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 50

Let's proceed to step 5:
When dividing 90 by 50, we get 1 with a remainder of 40.
Write down 1 as next digit of the result. 
Result so far: 261.0
Subtracting 50 from 90 leaves us with 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 6:
If we divide 400 by 50, we get 8 and a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 261.8
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.

Let's proceed to step 7:
If we divide 0 by 50, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 261.8
The remainder is 0 after subtracting 0 from 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 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 261.8
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 261.8 with a remainder of 0.0.
