We look at the division of 157508 by 75 
The aim is to understand the frequency of 75 in 157508.

Let's proceed to step 1:
If we divide 1 by 75, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 75

Moving on to step 2:
75 can be fit into 15 0 times, resulting in a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Include the next digit (7) from the dividend after 15, then repeat: 157 / 75

Going ahead to step 3:
When dividing 157 by 75, we get 2 with a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 150 from 157 to get 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 75

Let's proceed to step 4:
If we divide 75 by 75, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtract 75 from 75 to get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 75

Advancing to step 5:
0 divided by 75 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 210.0
Deduct 0 from 0 and we're left with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 75

Moving on to step 6:
75 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 2100.0
If we subtract 0 from 8, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
The number 75 fits into 80 1 times, leaving a remainder of 5.
The next digit of our result is 1. 
Result so far: 2100.1
If we subtract 75 from 80, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
When dividing 50 by 75, we get 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 2100.1
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 9:
75 can be fit into 500 6 times, resulting in a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 2100.106
The remainder is 50 after subtracting 450 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
75 goes into 500 6 times with a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 2100.1066
If we take 450 away from 500, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 2100.1066 and a remainder of 0.0005.
