875351 ÷ 75 
The aim is to understand the frequency of 75 in 875351.

Let's proceed to step 1:
75 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 75

Moving on to step 2:
If we divide 87 by 75, we get 1 and a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 12 after subtracting 75 from 87.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 75

Going ahead to step 3:
When dividing 125 by 75, we get 1 with a remainder of 50.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 50 after subtracting 75 from 125.
Fetch the next digit (3) from the dividend, attach it to 50 and continue: 503 / 75

Going ahead to step 4:
When dividing 503 by 75, we get 6 with a remainder of 53.
Record the quotient 6 as the next digit in the result. 
Result so far: 116.0
The remainder is 53 after subtracting 450 from 503.
Take the next digit (5) from the dividend and append it to 53, then repeat: 535 / 75

Moving on to step 5:
If we divide 535 by 75, we get 7 and a remainder of 10.
The next digit of our result is 7. 
Result so far: 1167.0
Subtract 525 from 535 to get 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 75

Step 6:
75 can be fit into 101 1 times, resulting in a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 11671.0
Subtract 75 from 101 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 7:
When dividing 260 by 75, we get 3 with a remainder of 35.
Put 3 as the next digit of the answer. 
Result so far: 11671.3
Subtracting 225 from 260 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 8:
If we divide 350 by 75, we get 4 and a remainder of 50.
Put 4 as the next digit of the answer. 
Result so far: 11671.34
Subtract 300 from 350 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 9:
500 divided by 75 is 6 with a remainder of 50.
The next digit of our result is 6. 
Result so far: 11671.346
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
The number 75 fits into 500 6 times, leaving a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 11671.3466
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 11671.3466 and a remainder of 0.0005.
