We're dividing 43431083 by 50 
The aim is to understand the frequency of 50 in 43431083.

Let's proceed to step 1:
When dividing 4 by 50, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 50

Step 2:
The number 50 fits into 43 0 times, leaving a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Grab the next digit (4) from the dividend, add it to 43, then carry on: 434 / 50

Advancing to step 3:
434 divided by 50 is 8 with a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 34 after subtracting 400 from 434.
Fetch the next digit (3) from the dividend, attach it to 34 and continue: 343 / 50

Advancing to step 4:
When dividing 343 by 50, we get 6 with a remainder of 43.
Use 6 as the next digit of our solution. 
Result so far: 86.0
If we subtract 300 from 343, we get 43.
Grab the next digit (1) from the dividend, add it to 43, then carry on: 431 / 50

Step 5:
When dividing 431 by 50, we get 8 with a remainder of 31.
Put 8 as the next digit of the answer. 
Result so far: 868.0
If we subtract 400 from 431, we get 31.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 50

Let's proceed to step 6:
The number 50 fits into 310 6 times, leaving a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 8686.0
Deduct 300 from 310 and we're left with 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 50

Advancing to step 7:
The number 50 fits into 108 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 86862.0
If we take 100 away from 108, we end up with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 50

Let's proceed to step 8:
When dividing 83 by 50, we get 1 with a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 868621.0
Deduct 50 from 83 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 9:
50 can be fit into 330 6 times, resulting in a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 868621.6
Subtracting 300 from 330 leaves us 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.

Let's proceed to step 10:
The number 50 fits into 300 6 times, leaving a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 868621.66
Subtracting 300 from 300 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 final result is 868621.66 with a remainder of 0.0.
