We look at the division of 16595516 by 266 
The aim is to understand the frequency of 266 in 16595516.

Going ahead to step 1:
The number 266 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 266

Step 2:
The number 266 fits into 16 0 times, leaving a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 266

Let's proceed to step 3:
165 divided by 266 is 0 with a remainder of 165.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 165 leaves us with 165.
Fetch the next digit (9) from the dividend, attach it to 165 and continue: 1659 / 266

Going ahead to step 4:
1659 divided by 266 is 6 with a remainder of 63.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 1596 from 1659 leaves us with 63.
Include the next digit (5) from the dividend after 63, then repeat: 635 / 266

Step 5:
If we divide 635 by 266, we get 2 and a remainder of 103.
Record the quotient 2 as the next digit in the result. 
Result so far: 62.0
Subtracting 532 from 635 leaves us with 103.
Grab the next digit (5) from the dividend, add it to 103, then carry on: 1035 / 266

Step 6:
The number 266 fits into 1035 3 times, leaving a remainder of 237.
Record the quotient 3 as the next digit in the result. 
Result so far: 623.0
If we take 798 away from 1035, we end up with 237.
Fetch the next digit (1) from the dividend, attach it to 237 and continue: 2371 / 266

Step 7:
266 goes into 2371 8 times with a remainder of 243.
Write down 8 as next digit of the result. 
Result so far: 6238.0
Deduct 2128 from 2371 and we're left with 243.
Include the next digit (6) from the dividend after 243, then repeat: 2436 / 266

On to step 8:
If we divide 2436 by 266, we get 9 and a remainder of 42.
The next digit of our result is 9. 
Result so far: 62389.0
If we take 2394 away from 2436, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 9:
When dividing 420 by 266, we get 1 with a remainder of 154.
The next digit of our result is 1. 
Result so far: 62389.1
If we take 266 away from 420, we end up with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Moving on to step 10:
1540 divided by 266 is 5 with a remainder of 210.
Use 5 as the next digit of our solution. 
Result so far: 62389.15
If we subtract 1330 from 1540, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 11:
When dividing 2100 by 266, we get 7 with a remainder of 238.
Use 7 as the next digit of our solution. 
Result so far: 62389.157
If we take 1862 away from 2100, we end up with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Let's proceed to step 12:
When dividing 2380 by 266, we get 8 with a remainder of 252.
Put 8 as the next digit of the answer. 
Result so far: 62389.1578
Deduct 2128 from 2380 and we're left with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 13:
2520 divided by 266 is 9 with a remainder of 126.
Write down 9 as next digit of the result. 
Result so far: 62389.15789
If we take 2394 away from 2520, we end up with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Going ahead to step 14:
266 can be fit into 1260 4 times, resulting in a remainder of 196.
Use 4 as the next digit of our solution. 
Result so far: 62389.157894
If we take 1064 away from 1260, we end up with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Moving on to step 15:
1960 divided by 266 is 7 with a remainder of 98.
The next digit of our result is 7. 
Result so far: 62389.1578947
Subtract 1862 from 1960 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 16:
The number 266 fits into 980 3 times, leaving a remainder of 182.
Write down 3 as next digit of the result. 
Result so far: 62389.15789473
The remainder is 182 after subtracting 798 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

The final result is 62389.15789473 with a remainder of 1.82e-07.
