We're dividing 52686525 by 50 
The aim is to understand the frequency of 50 in 52686525.

Going ahead to step 1:
When dividing 5 by 50, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 50

Let's proceed to step 2:
If we divide 52 by 50, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 50 away from 52, we end up with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 50

Let's proceed to step 3:
If we divide 26 by 50, we get 0 and a remainder of 26.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 26 leaves us with 26.
Fetch the next digit (8) from the dividend, attach it to 26 and continue: 268 / 50

Step 4:
When dividing 268 by 50, we get 5 with a remainder of 18.
Put 5 as the next digit of the answer. 
Result so far: 105.0
Subtracting 250 from 268 leaves us with 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 50

Moving on to step 5:
186 divided by 50 is 3 with a remainder of 36.
Record the quotient 3 as the next digit in the result. 
Result so far: 1053.0
Subtract 150 from 186 to get 36.
Fetch the next digit (5) from the dividend, attach it to 36 and continue: 365 / 50

Going ahead to step 6:
50 can be fit into 365 7 times, resulting in a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 10537.0
Deduct 350 from 365 and we're left with 15.
Fetch the next digit (2) from the dividend, attach it to 15 and continue: 152 / 50

Step 7:
50 can be fit into 152 3 times, resulting in a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 105373.0
Deduct 150 from 152 and we're left with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 50

Moving on to step 8:
25 divided by 50 is 0 with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 1053730.0
Subtracting 0 from 25 leaves us 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.

Moving on to step 9:
50 goes into 250 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 1053730.5
Subtracting 250 from 250 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.

Advancing to step 10:
0 divided by 50 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1053730.5
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.

Moving on to step 11:
50 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1053730.5
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.

The final outcome is 1053730.5, with a leftover of 0.0.
