We look at the division of 38053906 by 75 
The aim is to understand the frequency of 75 in 38053906.

Moving on to step 1:
3 divided by 75 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 75

Let's proceed to step 2:
The number 75 fits into 38 0 times, leaving a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Take the next digit (0) from the dividend and append it to 38, then repeat: 380 / 75

Going ahead to step 3:
380 divided by 75 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 375 from 380, we get 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 75

Let's proceed to step 4:
55 divided by 75 is 0 with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
Subtracting 0 from 55 leaves us with 55.
Bring next digit (3) of the dividend behind the 55 and repeat the process: 553 / 75

Going ahead to step 5:
When dividing 553 by 75, we get 7 with a remainder of 28.
Use 7 as the next digit of our solution. 
Result so far: 507.0
If we take 525 away from 553, we end up with 28.
Take the next digit (9) from the dividend and append it to 28, then repeat: 289 / 75

Step 6:
The number 75 fits into 289 3 times, leaving a remainder of 64.
The number 3 becomes the next digit in our result. 
Result so far: 5073.0
If we take 225 away from 289, we end up with 64.
Append the next digit (0) from the dividend to 64 and continue with: 640 / 75

Advancing to step 7:
75 goes into 640 8 times with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 50738.0
If we subtract 600 from 640, we get 40.
Fetch the next digit (6) from the dividend, attach it to 40 and continue: 406 / 75

Let's proceed to step 8:
If we divide 406 by 75, we get 5 and a remainder of 31.
Record the quotient 5 as the next digit in the result. 
Result so far: 507385.0
If we take 375 away from 406, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 9:
When dividing 310 by 75, we get 4 with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 507385.4
Subtract 300 from 310 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
When dividing 100 by 75, we get 1 with a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 507385.41
The remainder is 25 after subtracting 75 from 100.
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 11:
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: 507385.413
The remainder is 25 after subtracting 225 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 12:
250 divided by 75 is 3 with a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 507385.4133
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.

After the division, we end up with 507385.4133 and a remainder of 0.00025.
