We look at the division of 71286534 by 75 
The aim is to understand the frequency of 75 in 71286534.

Moving on to step 1:
If we divide 7 by 75, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 75

Let's proceed to step 2:
The number 75 fits into 71 0 times, leaving a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Grab the next digit (2) from the dividend, add it to 71, then carry on: 712 / 75

Going ahead to step 3:
The number 75 fits into 712 9 times, leaving a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 37 after subtracting 675 from 712.
Fetch the next digit (8) from the dividend, attach it to 37 and continue: 378 / 75

Going ahead to step 4:
When dividing 378 by 75, we get 5 with a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 95.0
The remainder is 3 after subtracting 375 from 378.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 75

Moving on to step 5:
36 divided by 75 is 0 with a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 950.0
Deduct 0 from 36 and we're left with 36.
Append the next digit (5) from the dividend to 36 and continue with: 365 / 75

Let's proceed to step 6:
If we divide 365 by 75, we get 4 and a remainder of 65.
The next digit of our result is 4. 
Result so far: 9504.0
If we take 300 away from 365, we end up with 65.
Include the next digit (3) from the dividend after 65, then repeat: 653 / 75

Going ahead to step 7:
75 can be fit into 653 8 times, resulting in a remainder of 53.
Write down 8 as next digit of the result. 
Result so far: 95048.0
If we subtract 600 from 653, we get 53.
Fetch the next digit (4) from the dividend, attach it to 53 and continue: 534 / 75

Going ahead to step 8:
75 goes into 534 7 times with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 950487.0
If we take 525 away from 534, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
75 goes into 90 1 times with a remainder of 15.
The next digit of our result is 1. 
Result so far: 950487.1
Subtract 75 from 90 to 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.

Step 10:
75 can be fit into 150 2 times, resulting in a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 950487.12
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.

Moving on to step 11:
75 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 950487.12
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.

Step 12:
The number 75 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 950487.12
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.

The quotient of the division is 950487.12, and the remainder is 0.0.
