We're dividing 149489 by 75 
The aim is to understand the frequency of 75 in 149489.

Let's proceed to step 1:
1 divided by 75 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 75

Moving on to step 2:
75 goes into 14 0 times with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 75

Let's proceed to step 3:
When dividing 149 by 75, we get 1 with a remainder of 74.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 75 away from 149, we end up with 74.
Append the next digit (4) from the dividend to 74 and continue with: 744 / 75

Moving on to step 4:
744 divided by 75 is 9 with a remainder of 69.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtract 675 from 744 to get 69.
Append the next digit (8) from the dividend to 69 and continue with: 698 / 75

On to step 5:
698 divided by 75 is 9 with a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 199.0
Deduct 675 from 698 and we're left with 23.
Fetch the next digit (9) from the dividend, attach it to 23 and continue: 239 / 75

Advancing to step 6:
239 divided by 75 is 3 with a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 1993.0
Subtracting 225 from 239 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
140 divided by 75 is 1 with a remainder of 65.
Use 1 as the next digit of our solution. 
Result so far: 1993.1
If we take 75 away from 140, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 8:
650 divided by 75 is 8 with a remainder of 50.
Use 8 as the next digit of our solution. 
Result so far: 1993.18
Deduct 600 from 650 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 9:
The number 75 fits into 500 6 times, leaving a remainder of 50.
Use 6 as the next digit of our solution. 
Result so far: 1993.186
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.

Advancing to step 10:
75 can be fit into 500 6 times, resulting in a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 1993.1866
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.

Our division results in 1993.1866 with a remaining 0.0005.
