We look at the division of 27315545 by 668 
The aim is to understand the frequency of 668 in 27315545.

Going ahead to step 1:
The number 668 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 668

Let's proceed to step 2:
668 can be fit into 27 0 times, resulting in a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 27 and we're left with 27.
Include the next digit (3) from the dividend after 27, then repeat: 273 / 668

Moving on to step 3:
When dividing 273 by 668, we get 0 with a remainder of 273.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 273 to get 273.
Fetch the next digit (1) from the dividend, attach it to 273 and continue: 2731 / 668

Advancing to step 4:
The number 668 fits into 2731 4 times, leaving a remainder of 59.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 2672 from 2731, we get 59.
Grab the next digit (5) from the dividend, add it to 59, then carry on: 595 / 668

Let's proceed to step 5:
595 divided by 668 is 0 with a remainder of 595.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
Deduct 0 from 595 and we're left with 595.
Take the next digit (5) from the dividend and append it to 595, then repeat: 5955 / 668

Advancing to step 6:
668 can be fit into 5955 8 times, resulting in a remainder of 611.
Record the quotient 8 as the next digit in the result. 
Result so far: 408.0
Deduct 5344 from 5955 and we're left with 611.
Grab the next digit (4) from the dividend, add it to 611, then carry on: 6114 / 668

Going ahead to step 7:
The number 668 fits into 6114 9 times, leaving a remainder of 102.
Put 9 as the next digit of the answer. 
Result so far: 4089.0
If we subtract 6012 from 6114, we get 102.
Include the next digit (5) from the dividend after 102, then repeat: 1025 / 668

Advancing to step 8:
668 goes into 1025 1 times with a remainder of 357.
Put 1 as the next digit of the answer. 
Result so far: 40891.0
If we take 668 away from 1025, we end up with 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Step 9:
668 goes into 3570 5 times with a remainder of 230.
Use 5 as the next digit of our solution. 
Result so far: 40891.5
If we subtract 3340 from 3570, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 10:
When dividing 2300 by 668, we get 3 with a remainder of 296.
Write down 3 as next digit of the result. 
Result so far: 40891.53
Subtracting 2004 from 2300 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Moving on to step 11:
2960 divided by 668 is 4 with a remainder of 288.
Put 4 as the next digit of the answer. 
Result so far: 40891.534
Deduct 2672 from 2960 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 12:
The number 668 fits into 2880 4 times, leaving a remainder of 208.
The number 4 becomes the next digit in our result. 
Result so far: 40891.5344
If we subtract 2672 from 2880, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

The final result is 40891.5344 with a remainder of 0.00208.
