We look at the division of 75468466 by 635 
The aim is to understand the frequency of 635 in 75468466.

Step 1:
When dividing 7 by 635, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 635

Advancing to step 2:
When dividing 75 by 635, we get 0 with a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 75, we end up with 75.
Take the next digit (4) from the dividend and append it to 75, then repeat: 754 / 635

Moving on to step 3:
If we divide 754 by 635, we get 1 and a remainder of 119.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 635 away from 754, we end up with 119.
Append the next digit (6) from the dividend to 119 and continue with: 1196 / 635

Advancing to step 4:
1196 divided by 635 is 1 with a remainder of 561.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 561 after subtracting 635 from 1196.
Include the next digit (8) from the dividend after 561, then repeat: 5618 / 635

Advancing to step 5:
If we divide 5618 by 635, we get 8 and a remainder of 538.
The number 8 becomes the next digit in our result. 
Result so far: 118.0
Subtract 5080 from 5618 to get 538.
Append the next digit (4) from the dividend to 538 and continue with: 5384 / 635

Moving on to step 6:
635 can be fit into 5384 8 times, resulting in a remainder of 304.
Write down 8 as next digit of the result. 
Result so far: 1188.0
If we take 5080 away from 5384, we end up with 304.
Take the next digit (6) from the dividend and append it to 304, then repeat: 3046 / 635

Step 7:
635 can be fit into 3046 4 times, resulting in a remainder of 506.
Use 4 as the next digit of our solution. 
Result so far: 11884.0
If we take 2540 away from 3046, we end up with 506.
Take the next digit (6) from the dividend and append it to 506, then repeat: 5066 / 635

On to step 8:
The number 635 fits into 5066 7 times, leaving a remainder of 621.
The number 7 becomes the next digit in our result. 
Result so far: 118847.0
Deduct 4445 from 5066 and we're left with 621.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6210, and continue the process.

Let's proceed to step 9:
When dividing 6210 by 635, we get 9 with a remainder of 495.
Record the quotient 9 as the next digit in the result. 
Result so far: 118847.9
Subtract 5715 from 6210 to get 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Advancing to step 10:
4950 divided by 635 is 7 with a remainder of 505.
Use 7 as the next digit of our solution. 
Result so far: 118847.97
If we subtract 4445 from 4950, we get 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Going ahead to step 11:
5050 divided by 635 is 7 with a remainder of 605.
The next digit of our result is 7. 
Result so far: 118847.977
Subtract 4445 from 5050 to get 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

The final result is 118847.977 with a remainder of 0.0605.
