We look at the division of 61197985 by 635 
The aim is to understand the frequency of 635 in 61197985.

Let's proceed to step 1:
6 divided by 635 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 635

Moving on to step 2:
If we divide 61 by 635, we get 0 and a remainder of 61.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 61 leaves us with 61.
Include the next digit (1) from the dividend after 61, then repeat: 611 / 635

Step 3:
When dividing 611 by 635, we get 0 with a remainder of 611.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 611 leaves us with 611.
Append the next digit (9) from the dividend to 611 and continue with: 6119 / 635

On to step 4:
If we divide 6119 by 635, we get 9 and a remainder of 404.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 5715 away from 6119, we end up with 404.
Fetch the next digit (7) from the dividend, attach it to 404 and continue: 4047 / 635

Step 5:
The number 635 fits into 4047 6 times, leaving a remainder of 237.
The number 6 becomes the next digit in our result. 
Result so far: 96.0
If we subtract 3810 from 4047, we get 237.
Include the next digit (9) from the dividend after 237, then repeat: 2379 / 635

Step 6:
635 goes into 2379 3 times with a remainder of 474.
Put 3 as the next digit of the answer. 
Result so far: 963.0
Subtracting 1905 from 2379 leaves us with 474.
Fetch the next digit (8) from the dividend, attach it to 474 and continue: 4748 / 635

On to step 7:
When dividing 4748 by 635, we get 7 with a remainder of 303.
The next digit of our result is 7. 
Result so far: 9637.0
If we take 4445 away from 4748, we end up with 303.
Take the next digit (5) from the dividend and append it to 303, then repeat: 3035 / 635

Step 8:
635 can be fit into 3035 4 times, resulting in a remainder of 495.
The next digit of our result is 4. 
Result so far: 96374.0
If we take 2540 away from 3035, 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.

Advancing to step 9:
635 goes into 4950 7 times with a remainder of 505.
Record the quotient 7 as the next digit in the result. 
Result so far: 96374.7
Deduct 4445 from 4950 and we're left 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.

Advancing to step 10:
635 can be fit into 5050 7 times, resulting in a remainder of 605.
Write down 7 as next digit of the result. 
Result so far: 96374.77
Deduct 4445 from 5050 and we're left 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 quotient of the division is 96374.77, and the remainder is 0.605.
