Let's divide 658691 by 75
The aim is to understand the frequency of 75 in 658691.

Moving on to step 1:
If we divide 6 by 75, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 75

Moving on to step 2:
When dividing 65 by 75, we get 0 with a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 65, we end up with 65.
Grab the next digit (8) from the dividend, add it to 65, then carry on: 658 / 75

Step 3:
The number 75 fits into 658 8 times, leaving a remainder of 58.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 600 from 658 leaves us with 58.
Take the next digit (6) from the dividend and append it to 58, then repeat: 586 / 75

Moving on to step 4:
75 can be fit into 586 7 times, resulting in a remainder of 61.
Put 7 as the next digit of the answer. 
Result so far: 87.0
The remainder is 61 after subtracting 525 from 586.
Grab the next digit (9) from the dividend, add it to 61, then carry on: 619 / 75

Advancing to step 5:
When dividing 619 by 75, we get 8 with a remainder of 19.
Put 8 as the next digit of the answer. 
Result so far: 878.0
If we take 600 away from 619, we end up with 19.
Include the next digit (1) from the dividend after 19, then repeat: 191 / 75

Moving on to step 6:
75 goes into 191 2 times with a remainder of 41.
Use 2 as the next digit of our solution. 
Result so far: 8782.0
If we subtract 150 from 191, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 7:
The number 75 fits into 410 5 times, leaving a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 8782.5
Subtract 375 from 410 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 8:
75 goes into 350 4 times with a remainder of 50.
The number 4 becomes the next digit in our result. 
Result so far: 8782.54
If we subtract 300 from 350, 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.

Advancing to step 9:
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: 8782.546
Subtracting 450 from 500 leaves us 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.

Going ahead to step 10:
75 goes into 500 6 times with a remainder of 50.
The next digit of our result is 6. 
Result so far: 8782.5466
Subtracting 450 from 500 leaves us 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.

The final outcome is 8782.5466, with a leftover of 0.0005.
