126546 ÷ 75 
The aim is to understand the frequency of 75 in 126546.

Going ahead to step 1:
75 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 75

Moving on to step 2:
When dividing 12 by 75, we get 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Bring next digit (6) of the dividend behind the 12 and repeat the process: 126 / 75

Going ahead to step 3:
126 divided by 75 is 1 with a remainder of 51.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 75 from 126 to get 51.
Fetch the next digit (5) from the dividend, attach it to 51 and continue: 515 / 75

Advancing to step 4:
515 divided by 75 is 6 with a remainder of 65.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we take 450 away from 515, we end up with 65.
Take the next digit (4) from the dividend and append it to 65, then repeat: 654 / 75

Let's proceed to step 5:
75 goes into 654 8 times with a remainder of 54.
The next digit of our result is 8. 
Result so far: 168.0
Subtract 600 from 654 to get 54.
Include the next digit (6) from the dividend after 54, then repeat: 546 / 75

Let's proceed to step 6:
The number 75 fits into 546 7 times, leaving a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 1687.0
If we subtract 525 from 546, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
75 can be fit into 210 2 times, resulting in a remainder of 60.
The next digit of our result is 2. 
Result so far: 1687.2
Subtract 150 from 210 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
75 can be fit into 600 8 times, resulting in a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 1687.28
Subtract 600 from 600 to 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 9:
The number 75 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1687.28
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
When dividing 0 by 75, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1687.28
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 1687.28, and the remainder is 0.0.
