We're dividing 74129383 by 50 
The aim is to understand the frequency of 50 in 74129383.

Advancing to step 1:
50 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 50

On to step 2:
If we divide 74 by 50, we get 1 and a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 50 from 74 leaves us with 24.
Fetch the next digit (1) from the dividend, attach it to 24 and continue: 241 / 50

On to step 3:
When dividing 241 by 50, we get 4 with a remainder of 41.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we take 200 away from 241, we end up with 41.
Bring next digit (2) of the dividend behind the 41 and repeat the process: 412 / 50

Advancing to step 4:
If we divide 412 by 50, we get 8 and a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 148.0
Subtracting 400 from 412 leaves us with 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 50

Step 5:
129 divided by 50 is 2 with a remainder of 29.
The next digit of our result is 2. 
Result so far: 1482.0
Subtracting 100 from 129 leaves us with 29.
Take the next digit (3) from the dividend and append it to 29, then repeat: 293 / 50

Let's proceed to step 6:
293 divided by 50 is 5 with a remainder of 43.
Use 5 as the next digit of our solution. 
Result so far: 14825.0
Deduct 250 from 293 and we're left with 43.
Fetch the next digit (8) from the dividend, attach it to 43 and continue: 438 / 50

Advancing to step 7:
50 can be fit into 438 8 times, resulting in a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 148258.0
Subtracting 400 from 438 leaves us with 38.
Take the next digit (3) from the dividend and append it to 38, then repeat: 383 / 50

Advancing to step 8:
383 divided by 50 is 7 with a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 1482587.0
If we take 350 away from 383, we end up 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:
If we divide 330 by 50, we get 6 and a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 1482587.6
Deduct 300 from 330 and we're left 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.

Going ahead to step 10:
The number 50 fits into 300 6 times, leaving a remainder of 0.
The next digit of our result is 6. 
Result so far: 1482587.66
Subtract 300 from 300 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.

The quotient of the division is 1482587.66, and the remainder is 0.0.
