We look at the division of 71669225 by 50 
The aim is to understand the frequency of 50 in 71669225.

Moving on to step 1:
50 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 50

On to step 2:
The number 50 fits into 71 1 times, leaving a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 50 away from 71, we end up with 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 50

Going ahead to step 3:
If we divide 216 by 50, we get 4 and a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 200 from 216 and we're left with 16.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 50

Going ahead to step 4:
When dividing 166 by 50, we get 3 with a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 143.0
Deduct 150 from 166 and we're left with 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 50

Let's proceed to step 5:
When dividing 169 by 50, we get 3 with a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 1433.0
Subtract 150 from 169 to get 19.
Bring next digit (2) of the dividend behind the 19 and repeat the process: 192 / 50

Going ahead to step 6:
50 can be fit into 192 3 times, resulting in a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 14333.0
Subtract 150 from 192 to get 42.
Append the next digit (2) from the dividend to 42 and continue with: 422 / 50

Going ahead to step 7:
If we divide 422 by 50, we get 8 and a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 143338.0
The remainder is 22 after subtracting 400 from 422.
Append the next digit (5) from the dividend to 22 and continue with: 225 / 50

Advancing to step 8:
The number 50 fits into 225 4 times, leaving a remainder of 25.
The number 4 becomes the next digit in our result. 
Result so far: 1433384.0
Deduct 200 from 225 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
The number 50 fits into 250 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 1433384.5
The remainder is 0 after subtracting 250 from 250.
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 10:
50 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 1433384.5
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.

Let's proceed to step 11:
If we divide 0 by 50, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1433384.5
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 outcome is 1433384.5, with a leftover of 0.0.
