We're dividing 635799 by 75 
The aim is to understand the frequency of 75 in 635799.

Going ahead to step 1:
6 divided by 75 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 75

Advancing to step 2:
75 goes into 63 0 times with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Take the next digit (5) from the dividend and append it to 63, then repeat: 635 / 75

Going ahead to step 3:
75 goes into 635 8 times with a remainder of 35.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 600 from 635 and we're left with 35.
Take the next digit (7) from the dividend and append it to 35, then repeat: 357 / 75

Going ahead to step 4:
357 divided by 75 is 4 with a remainder of 57.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
Deduct 300 from 357 and we're left with 57.
Bring next digit (9) of the dividend behind the 57 and repeat the process: 579 / 75

Let's proceed to step 5:
75 can be fit into 579 7 times, resulting in a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 847.0
Deduct 525 from 579 and we're left with 54.
Include the next digit (9) from the dividend after 54, then repeat: 549 / 75

Moving on to step 6:
The number 75 fits into 549 7 times, leaving a remainder of 24.
The next digit of our result is 7. 
Result so far: 8477.0
Deduct 525 from 549 and we're left 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.

Let's proceed to step 7:
If we divide 240 by 75, we get 3 and a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 8477.3
Subtracting 225 from 240 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
150 divided by 75 is 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 8477.32
If we subtract 150 from 150, 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.

Going ahead to step 9:
75 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8477.32
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.

Moving on to step 10:
When dividing 0 by 75, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8477.32
If we take 0 away from 0, we end up 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 8477.32, and the remainder is 0.0.
