Let's divide 158020 by 75
The aim is to understand the frequency of 75 in 158020.

Going ahead to step 1:
When dividing 1 by 75, we get 0 with a remainder of 1.
The next digit of our result is 0. 
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

Let's proceed to step 2:
The number 75 fits into 15 0 times, leaving a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 75

Step 3:
If we divide 158 by 75, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 2.0
If we take 150 away from 158, we end up with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 75

On to step 4:
The number 75 fits into 80 1 times, leaving a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtract 75 from 80 to get 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 75

Advancing to step 5:
75 goes into 52 0 times with a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 210.0
If we take 0 away from 52, we end up with 52.
Fetch the next digit (0) from the dividend, attach it to 52 and continue: 520 / 75

Going ahead to step 6:
75 goes into 520 6 times with a remainder of 70.
The next digit of our result is 6. 
Result so far: 2106.0
Deduct 450 from 520 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 7:
If we divide 700 by 75, we get 9 and a remainder of 25.
Use 9 as the next digit of our solution. 
Result so far: 2106.9
Subtract 675 from 700 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 8:
When dividing 250 by 75, we get 3 with a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 2106.93
If we take 225 away from 250, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
When dividing 250 by 75, we get 3 with a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 2106.933
If we subtract 225 from 250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 2106.933 and a remainder of 0.0025.
