We're dividing 144449 by 75 
The aim is to understand the frequency of 75 in 144449.

Going ahead to step 1:
75 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 75

On to step 2:
When dividing 14 by 75, we get 0 with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Append the next digit (4) from the dividend to 14 and continue with: 144 / 75

Step 3:
75 can be fit into 144 1 times, resulting in a remainder of 69.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 69 after subtracting 75 from 144.
Take the next digit (4) from the dividend and append it to 69, then repeat: 694 / 75

Advancing to step 4:
If we divide 694 by 75, we get 9 and a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we take 675 away from 694, we end up with 19.
Take the next digit (4) from the dividend and append it to 19, then repeat: 194 / 75

On to step 5:
When dividing 194 by 75, we get 2 with a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 192.0
If we subtract 150 from 194, we get 44.
Fetch the next digit (9) from the dividend, attach it to 44 and continue: 449 / 75

Step 6:
75 goes into 449 5 times with a remainder of 74.
The next digit of our result is 5. 
Result so far: 1925.0
The remainder is 74 after subtracting 375 from 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 7:
75 can be fit into 740 9 times, resulting in a remainder of 65.
The next digit of our result is 9. 
Result so far: 1925.9
The remainder is 65 after subtracting 675 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 8:
If we divide 650 by 75, we get 8 and a remainder of 50.
The next digit of our result is 8. 
Result so far: 1925.98
Subtract 600 from 650 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
If we divide 500 by 75, we get 6 and a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 1925.986
Deduct 450 from 500 and we're left 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.

Let's proceed to step 10:
If we divide 500 by 75, we get 6 and a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 1925.9866
If we subtract 450 from 500, we get 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 1925.9866 and a remainder of 0.0005.
