We're dividing 170896 by 75 
The aim is to understand the frequency of 75 in 170896.

Going ahead to step 1:
75 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 75

Step 2:
When dividing 17 by 75, we get 0 with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 75

Going ahead to step 3:
75 can be fit into 170 2 times, resulting in a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 150 from 170 to get 20.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 75

Advancing to step 4:
75 can be fit into 208 2 times, resulting in a remainder of 58.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Deduct 150 from 208 and we're left with 58.
Take the next digit (9) from the dividend and append it to 58, then repeat: 589 / 75

On to step 5:
589 divided by 75 is 7 with a remainder of 64.
Record the quotient 7 as the next digit in the result. 
Result so far: 227.0
Deduct 525 from 589 and we're left with 64.
Bring next digit (6) of the dividend behind the 64 and repeat the process: 646 / 75

Moving on to step 6:
75 goes into 646 8 times with a remainder of 46.
Record the quotient 8 as the next digit in the result. 
Result so far: 2278.0
Subtracting 600 from 646 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 7:
460 divided by 75 is 6 with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 2278.6
If we take 450 away from 460, we end up 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.

Step 8:
The number 75 fits into 100 1 times, leaving a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 2278.61
If we take 75 away from 100, we end up with 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:
If we divide 250 by 75, we get 3 and a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 2278.613
Subtracting 225 from 250 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 10:
If we divide 250 by 75, we get 3 and a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 2278.6133
If we take 225 away from 250, we end up with 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 outcome is 2278.6133, with a leftover of 0.00025.
