We look at the division of 66708068 by 50 
The aim is to understand the frequency of 50 in 66708068.

Going ahead to step 1:
The number 50 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 50

Step 2:
66 divided by 50 is 1 with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 50 from 66 and we're left with 16.
Fetch the next digit (7) from the dividend, attach it to 16 and continue: 167 / 50

On to step 3:
When dividing 167 by 50, we get 3 with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 150 from 167 leaves us with 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 50

Advancing to step 4:
170 divided by 50 is 3 with a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 133.0
If we subtract 150 from 170, we get 20.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 50

Going ahead to step 5:
50 goes into 208 4 times with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 1334.0
If we subtract 200 from 208, we get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 50

Advancing to step 6:
When dividing 80 by 50, we get 1 with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 13341.0
Subtract 50 from 80 to get 30.
Grab the next digit (6) from the dividend, add it to 30, then carry on: 306 / 50

On to step 7:
The number 50 fits into 306 6 times, leaving a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 133416.0
Deduct 300 from 306 and we're left with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 50

Let's proceed to step 8:
50 goes into 68 1 times with a remainder of 18.
The next digit of our result is 1. 
Result so far: 1334161.0
If we take 50 away from 68, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 9:
50 goes into 180 3 times with a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 1334161.3
The remainder is 30 after subtracting 150 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
50 can be fit into 300 6 times, resulting in a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 1334161.36
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.

Advancing to step 11:
0 divided by 50 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1334161.36
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.

Going ahead to step 12:
50 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1334161.36
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.

Our division results in 1334161.36 with a remaining 0.0.
