We look at the division of 612699 by 75 
The aim is to understand the frequency of 75 in 612699.

Step 1:
When dividing 6 by 75, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 75

On to step 2:
If we divide 61 by 75, we get 0 and a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 61 and we're left with 61.
Take the next digit (2) from the dividend and append it to 61, then repeat: 612 / 75

Let's proceed to step 3:
If we divide 612 by 75, we get 8 and a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 600 from 612 leaves us with 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 75

Let's proceed to step 4:
75 can be fit into 126 1 times, resulting in a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 81.0
If we subtract 75 from 126, we get 51.
Grab the next digit (9) from the dividend, add it to 51, then carry on: 519 / 75

Let's proceed to step 5:
If we divide 519 by 75, we get 6 and a remainder of 69.
Record the quotient 6 as the next digit in the result. 
Result so far: 816.0
The remainder is 69 after subtracting 450 from 519.
Include the next digit (9) from the dividend after 69, then repeat: 699 / 75

Advancing to step 6:
The number 75 fits into 699 9 times, leaving a remainder of 24.
Put 9 as the next digit of the answer. 
Result so far: 8169.0
Subtract 675 from 699 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 7:
The number 75 fits into 240 3 times, leaving a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 8169.3
Subtract 225 from 240 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 8:
75 can be fit into 150 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 8169.32
The remainder is 0 after subtracting 150 from 150.
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.
Write down 0 as next digit of the result. 
Result so far: 8169.32
Subtract 0 from 0 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.

Going ahead to step 10:
0 divided by 75 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8169.32
If we take 0 away from 0, we end up 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 final outcome is 8169.32, with a leftover of 0.0.
