681489 divided by 75 
The aim is to understand the frequency of 75 in 681489.

Moving on to step 1:
6 divided by 75 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 75

Advancing to step 2:
The number 75 fits into 68 0 times, leaving a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Append the next digit (1) from the dividend to 68 and continue with: 681 / 75

Advancing to step 3:
681 divided by 75 is 9 with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 675 from 681 and we're left with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 75

Going ahead to step 4:
If we divide 64 by 75, we get 0 and a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 90.0
Deduct 0 from 64 and we're left with 64.
Take the next digit (8) from the dividend and append it to 64, then repeat: 648 / 75

Moving on to step 5:
The number 75 fits into 648 8 times, leaving a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 908.0
Subtracting 600 from 648 leaves us with 48.
Grab the next digit (9) from the dividend, add it to 48, then carry on: 489 / 75

Going ahead to step 6:
When dividing 489 by 75, we get 6 with a remainder of 39.
The next digit of our result is 6. 
Result so far: 9086.0
Deduct 450 from 489 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
If we divide 390 by 75, we get 5 and a remainder of 15.
The next digit of our result is 5. 
Result so far: 9086.5
Deduct 375 from 390 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 8:
The number 75 fits into 150 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 9086.52
Subtract 150 from 150 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.

Let's proceed to step 9:
The number 75 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 9086.52
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.

On to step 10:
75 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9086.52
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.

The final result is 9086.52 with a remainder of 0.0.
