We look at the division of 17695665 by 635 
The aim is to understand the frequency of 635 in 17695665.

Going ahead to step 1:
635 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 635

Advancing to step 2:
When dividing 17 by 635, we get 0 with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Fetch the next digit (6) from the dividend, attach it to 17 and continue: 176 / 635

Moving on to step 3:
If we divide 176 by 635, we get 0 and a remainder of 176.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 176, we get 176.
Append the next digit (9) from the dividend to 176 and continue with: 1769 / 635

Step 4:
When dividing 1769 by 635, we get 2 with a remainder of 499.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 1270 from 1769 leaves us with 499.
Bring next digit (5) of the dividend behind the 499 and repeat the process: 4995 / 635

Going ahead to step 5:
635 goes into 4995 7 times with a remainder of 550.
Write down 7 as next digit of the result. 
Result so far: 27.0
The remainder is 550 after subtracting 4445 from 4995.
Take the next digit (6) from the dividend and append it to 550, then repeat: 5506 / 635

On to step 6:
If we divide 5506 by 635, we get 8 and a remainder of 426.
Use 8 as the next digit of our solution. 
Result so far: 278.0
Deduct 5080 from 5506 and we're left with 426.
Append the next digit (6) from the dividend to 426 and continue with: 4266 / 635

On to step 7:
4266 divided by 635 is 6 with a remainder of 456.
The next digit of our result is 6. 
Result so far: 2786.0
Subtracting 3810 from 4266 leaves us with 456.
Fetch the next digit (5) from the dividend, attach it to 456 and continue: 4565 / 635

On to step 8:
635 can be fit into 4565 7 times, resulting in a remainder of 120.
Write down 7 as next digit of the result. 
Result so far: 27867.0
Subtracting 4445 from 4565 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 9:
If we divide 1200 by 635, we get 1 and a remainder of 565.
The next digit of our result is 1. 
Result so far: 27867.1
Subtract 635 from 1200 to get 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Advancing to step 10:
635 can be fit into 5650 8 times, resulting in a remainder of 570.
The number 8 becomes the next digit in our result. 
Result so far: 27867.18
If we take 5080 away from 5650, we end up with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Moving on to step 11:
If we divide 5700 by 635, we get 8 and a remainder of 620.
The next digit of our result is 8. 
Result so far: 27867.188
Deduct 5080 from 5700 and we're left with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

The final result is 27867.188 with a remainder of 0.062.
