We look at the division of 49016965 by 966 
The aim is to understand the frequency of 966 in 49016965.

Let's proceed to step 1:
The number 966 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 966

Going ahead to step 2:
49 divided by 966 is 0 with a remainder of 49.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 49 leaves us with 49.
Fetch the next digit (0) from the dividend, attach it to 49 and continue: 490 / 966

On to step 3:
If we divide 490 by 966, we get 0 and a remainder of 490.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 490 after subtracting 0 from 490.
Append the next digit (1) from the dividend to 490 and continue with: 4901 / 966

Let's proceed to step 4:
If we divide 4901 by 966, we get 5 and a remainder of 71.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 4830 from 4901 leaves us with 71.
Grab the next digit (6) from the dividend, add it to 71, then carry on: 716 / 966

Step 5:
If we divide 716 by 966, we get 0 and a remainder of 716.
Put 0 as the next digit of the answer. 
Result so far: 50.0
Subtract 0 from 716 to get 716.
Fetch the next digit (9) from the dividend, attach it to 716 and continue: 7169 / 966

Step 6:
When dividing 7169 by 966, we get 7 with a remainder of 407.
The number 7 becomes the next digit in our result. 
Result so far: 507.0
Deduct 6762 from 7169 and we're left with 407.
Fetch the next digit (6) from the dividend, attach it to 407 and continue: 4076 / 966

Step 7:
If we divide 4076 by 966, we get 4 and a remainder of 212.
Record the quotient 4 as the next digit in the result. 
Result so far: 5074.0
Subtract 3864 from 4076 to get 212.
Include the next digit (5) from the dividend after 212, then repeat: 2125 / 966

Advancing to step 8:
If we divide 2125 by 966, we get 2 and a remainder of 193.
Use 2 as the next digit of our solution. 
Result so far: 50742.0
Deduct 1932 from 2125 and we're left with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Step 9:
1930 divided by 966 is 1 with a remainder of 964.
Use 1 as the next digit of our solution. 
Result so far: 50742.1
If we subtract 966 from 1930, we get 964.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9640, and continue the process.

Step 10:
When dividing 9640 by 966, we get 9 with a remainder of 946.
Write down 9 as next digit of the result. 
Result so far: 50742.19
Deduct 8694 from 9640 and we're left with 946.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9460, and continue the process.

On to step 11:
The number 966 fits into 9460 9 times, leaving a remainder of 766.
Write down 9 as next digit of the result. 
Result so far: 50742.199
Subtracting 8694 from 9460 leaves us with 766.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7660, and continue the process.

The final result is 50742.199 with a remainder of 0.0766.
