We're dividing 867957 by 75 
The aim is to understand the frequency of 75 in 867957.

Going ahead to step 1:
The number 75 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 75

Moving on to step 2:
75 can be fit into 86 1 times, resulting in a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 75 away from 86, we end up with 11.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 75

Moving on to step 3:
If we divide 117 by 75, we get 1 and a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 42 after subtracting 75 from 117.
Grab the next digit (9) from the dividend, add it to 42, then carry on: 429 / 75

Advancing to step 4:
When dividing 429 by 75, we get 5 with a remainder of 54.
The number 5 becomes the next digit in our result. 
Result so far: 115.0
Deduct 375 from 429 and we're left with 54.
Fetch the next digit (5) from the dividend, attach it to 54 and continue: 545 / 75

On to step 5:
If we divide 545 by 75, we get 7 and a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 1157.0
If we subtract 525 from 545, we get 20.
Bring next digit (7) of the dividend behind the 20 and repeat the process: 207 / 75

On to step 6:
The number 75 fits into 207 2 times, leaving a remainder of 57.
The number 2 becomes the next digit in our result. 
Result so far: 11572.0
The remainder is 57 after subtracting 150 from 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 7:
570 divided by 75 is 7 with a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 11572.7
The remainder is 45 after subtracting 525 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 8:
When dividing 450 by 75, we get 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 11572.76
Subtracting 450 from 450 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.

Step 9:
If we divide 0 by 75, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 11572.76
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.

Advancing to step 10:
If we divide 0 by 75, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11572.76
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.

After the division, we end up with 11572.76 and a remainder of 0.0.
