We divide 679891 by 75
The aim is to understand the frequency of 75 in 679891.

Moving on to step 1:
If we divide 6 by 75, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 75

Let's proceed to step 2:
75 goes into 67 0 times with a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Fetch the next digit (9) from the dividend, attach it to 67 and continue: 679 / 75

Step 3:
75 goes into 679 9 times with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 675 from 679 to get 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 75

Moving on to step 4:
The number 75 fits into 48 0 times, leaving a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
If we subtract 0 from 48, we get 48.
Fetch the next digit (9) from the dividend, attach it to 48 and continue: 489 / 75

Going ahead to step 5:
75 can be fit into 489 6 times, resulting in a remainder of 39.
The number 6 becomes the next digit in our result. 
Result so far: 906.0
If we take 450 away from 489, we end up with 39.
Include the next digit (1) from the dividend after 39, then repeat: 391 / 75

Advancing to step 6:
If we divide 391 by 75, we get 5 and a remainder of 16.
Use 5 as the next digit of our solution. 
Result so far: 9065.0
Subtract 375 from 391 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
75 can be fit into 160 2 times, resulting in a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 9065.2
Subtracting 150 from 160 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
When dividing 100 by 75, we get 1 with a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 9065.21
If we subtract 75 from 100, we 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.

On to step 9:
The number 75 fits into 250 3 times, leaving a remainder of 25.
The next digit of our result is 3. 
Result so far: 9065.213
If we subtract 225 from 250, we 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.

Advancing to step 10:
If we divide 250 by 75, we get 3 and a remainder of 25.
The next digit of our result is 3. 
Result so far: 9065.2133
If we subtract 225 from 250, we 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.

In conclusion, the division gives 9065.2133 with a balance of 0.00025.
