We look at the division of 19385280 by 635 
The aim is to understand the frequency of 635 in 19385280.

Moving on to step 1:
635 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 635

Step 2:
635 can be fit into 19 0 times, resulting in a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Include the next digit (3) from the dividend after 19, then repeat: 193 / 635

On to step 3:
635 goes into 193 0 times with a remainder of 193.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 193, we get 193.
Fetch the next digit (8) from the dividend, attach it to 193 and continue: 1938 / 635

On to step 4:
If we divide 1938 by 635, we get 3 and a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 1905 from 1938 and we're left with 33.
Grab the next digit (5) from the dividend, add it to 33, then carry on: 335 / 635

Advancing to step 5:
The number 635 fits into 335 0 times, leaving a remainder of 335.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Deduct 0 from 335 and we're left with 335.
Fetch the next digit (2) from the dividend, attach it to 335 and continue: 3352 / 635

Going ahead to step 6:
635 goes into 3352 5 times with a remainder of 177.
Use 5 as the next digit of our solution. 
Result so far: 305.0
Deduct 3175 from 3352 and we're left with 177.
Include the next digit (8) from the dividend after 177, then repeat: 1778 / 635

On to step 7:
1778 divided by 635 is 2 with a remainder of 508.
The number 2 becomes the next digit in our result. 
Result so far: 3052.0
The remainder is 508 after subtracting 1270 from 1778.
Fetch the next digit (0) from the dividend, attach it to 508 and continue: 5080 / 635

Let's proceed to step 8:
The number 635 fits into 5080 8 times, leaving a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 30528.0
The remainder is 0 after subtracting 5080 from 5080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
635 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 30528.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
When dividing 0 by 635, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 30528.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 30528.0, and the remainder is 0.0.
