We look at the division of 53928669 by 635 
The aim is to understand the frequency of 635 in 53928669.

Moving on to step 1:
635 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 635

Moving on to step 2:
53 divided by 635 is 0 with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Fetch the next digit (9) from the dividend, attach it to 53 and continue: 539 / 635

Step 3:
539 divided by 635 is 0 with a remainder of 539.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 539 leaves us with 539.
Append the next digit (2) from the dividend to 539 and continue with: 5392 / 635

On to step 4:
If we divide 5392 by 635, we get 8 and a remainder of 312.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 5080 from 5392 to get 312.
Grab the next digit (8) from the dividend, add it to 312, then carry on: 3128 / 635

Going ahead to step 5:
When dividing 3128 by 635, we get 4 with a remainder of 588.
The next digit of our result is 4. 
Result so far: 84.0
Subtract 2540 from 3128 to get 588.
Take the next digit (6) from the dividend and append it to 588, then repeat: 5886 / 635

Advancing to step 6:
When dividing 5886 by 635, we get 9 with a remainder of 171.
Write down 9 as next digit of the result. 
Result so far: 849.0
Subtracting 5715 from 5886 leaves us with 171.
Take the next digit (6) from the dividend and append it to 171, then repeat: 1716 / 635

Advancing to step 7:
635 can be fit into 1716 2 times, resulting in a remainder of 446.
Put 2 as the next digit of the answer. 
Result so far: 8492.0
The remainder is 446 after subtracting 1270 from 1716.
Include the next digit (9) from the dividend after 446, then repeat: 4469 / 635

Step 8:
When dividing 4469 by 635, we get 7 with a remainder of 24.
The number 7 becomes the next digit in our result. 
Result so far: 84927.0
Subtracting 4445 from 4469 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 9:
The number 635 fits into 240 0 times, leaving a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 84927.0
If we take 0 away from 240, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 10:
635 can be fit into 2400 3 times, resulting in a remainder of 495.
Write down 3 as next digit of the result. 
Result so far: 84927.03
If we take 1905 away from 2400, we end up with 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Going ahead to step 11:
4950 divided by 635 is 7 with a remainder of 505.
Record the quotient 7 as the next digit in the result. 
Result so far: 84927.037
Subtracting 4445 from 4950 leaves us with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Moving on to step 12:
635 goes into 5050 7 times with a remainder of 605.
Put 7 as the next digit of the answer. 
Result so far: 84927.0377
Subtracting 4445 from 5050 leaves us with 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 84927.0377 with a remainder of 0.00605.
