We look at the division of 681849 by 75 
The aim is to understand the frequency of 75 in 681849.

Let's proceed to step 1:
6 divided by 75 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 75

Moving on to step 2:
The number 75 fits into 68 0 times, leaving a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Grab the next digit (1) from the dividend, add it to 68, then carry on: 681 / 75

Moving on 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.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 75

Going ahead to step 4:
75 can be fit into 68 0 times, resulting in a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 90.0
If we take 0 away from 68, we end up with 68.
Grab the next digit (4) from the dividend, add it to 68, then carry on: 684 / 75

Going ahead to step 5:
When dividing 684 by 75, we get 9 with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 909.0
Subtracting 675 from 684 leaves us with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 75

Moving on to step 6:
75 can be fit into 99 1 times, resulting in a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 9091.0
Deduct 75 from 99 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 7:
75 goes into 240 3 times with a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 9091.3
If we subtract 225 from 240, we 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.

Advancing to step 8:
When dividing 150 by 75, we get 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 9091.32
Subtracting 150 from 150 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.

Let's proceed to step 9:
75 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9091.32
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.

Let's proceed 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: 9091.32
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 9091.32 with a remainder of 0.0.
