Let's divide 69887683 by 75
The aim is to understand the frequency of 75 in 69887683.

On to step 1:
75 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 75

Step 2:
69 divided by 75 is 0 with a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 69 leaves us with 69.
Fetch the next digit (8) from the dividend, attach it to 69 and continue: 698 / 75

Going ahead to step 3:
75 can be fit into 698 9 times, resulting in a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 675 from 698 and we're left with 23.
Fetch the next digit (8) from the dividend, attach it to 23 and continue: 238 / 75

On to step 4:
75 goes into 238 3 times with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 93.0
Subtracting 225 from 238 leaves us with 13.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 75

Moving on to step 5:
If we divide 137 by 75, we get 1 and a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 931.0
Subtract 75 from 137 to get 62.
Include the next digit (6) from the dividend after 62, then repeat: 626 / 75

Moving on to step 6:
The number 75 fits into 626 8 times, leaving a remainder of 26.
The number 8 becomes the next digit in our result. 
Result so far: 9318.0
If we subtract 600 from 626, we get 26.
Take the next digit (8) from the dividend and append it to 26, then repeat: 268 / 75

Let's proceed to step 7:
75 can be fit into 268 3 times, resulting in a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 93183.0
Subtracting 225 from 268 leaves us with 43.
Take the next digit (3) from the dividend and append it to 43, then repeat: 433 / 75

Advancing to step 8:
75 can be fit into 433 5 times, resulting in a remainder of 58.
Use 5 as the next digit of our solution. 
Result so far: 931835.0
If we subtract 375 from 433, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 9:
When dividing 580 by 75, we get 7 with a remainder of 55.
Put 7 as the next digit of the answer. 
Result so far: 931835.7
The remainder is 55 after subtracting 525 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 10:
If we divide 550 by 75, we get 7 and a remainder of 25.
The next digit of our result is 7. 
Result so far: 931835.77
Subtract 525 from 550 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.

The final result is 931835.77 with a remainder of 0.025.
