159102 divided by 75 
The aim is to understand the frequency of 75 in 159102.

Let's proceed to step 1:
1 divided by 75 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 75

Step 2:
75 goes into 15 0 times with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 75

Let's proceed to step 3:
75 can be fit into 159 2 times, resulting in a remainder of 9.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 150 from 159 leaves us with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 75

Going ahead to step 4:
When dividing 91 by 75, we get 1 with a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 21.0
Deduct 75 from 91 and we're left with 16.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 75

Moving on to step 5:
When dividing 160 by 75, we get 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 212.0
The remainder is 10 after subtracting 150 from 160.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 75

Moving on to step 6:
If we divide 102 by 75, we get 1 and a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 2121.0
Subtracting 75 from 102 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 7:
270 divided by 75 is 3 with a remainder of 45.
The number 3 becomes the next digit in our result. 
Result so far: 2121.3
The remainder is 45 after subtracting 225 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 8:
75 goes into 450 6 times with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 2121.36
If we subtract 450 from 450, 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.

On to step 9:
If we divide 0 by 75, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2121.36
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:
The number 75 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2121.36
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.

After the division, we end up with 2121.36 and a remainder of 0.0.
