We're dividing 603954 by 75 
The aim is to understand the frequency of 75 in 603954.

Moving on to step 1:
When dividing 6 by 75, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 75

Let's proceed to step 2:
75 can be fit into 60 0 times, resulting in a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 60, we get 60.
Fetch the next digit (3) from the dividend, attach it to 60 and continue: 603 / 75

Step 3:
603 divided by 75 is 8 with a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 600 away from 603, we end up with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 75

Let's proceed to step 4:
If we divide 39 by 75, we get 0 and a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
The remainder is 39 after subtracting 0 from 39.
Bring next digit (5) of the dividend behind the 39 and repeat the process: 395 / 75

Step 5:
395 divided by 75 is 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 805.0
If we subtract 375 from 395, we get 20.
Take the next digit (4) from the dividend and append it to 20, then repeat: 204 / 75

Let's proceed to step 6:
204 divided by 75 is 2 with a remainder of 54.
Write down 2 as next digit of the result. 
Result so far: 8052.0
Subtract 150 from 204 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 7:
When dividing 540 by 75, we get 7 with a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 8052.7
Subtracting 525 from 540 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.
Record the quotient 2 as the next digit in the result. 
Result so far: 8052.72
The remainder is 0 after subtracting 150 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
0 divided by 75 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8052.72
Deduct 0 from 0 and we're left 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.

On to step 10:
0 divided by 75 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8052.72
The remainder is 0 after subtracting 0 from 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 8052.72, and the remainder is 0.0.
