We look at the division of 977178 by 75 
The aim is to understand the frequency of 75 in 977178.

Step 1:
When dividing 9 by 75, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 75

Moving on to step 2:
If we divide 97 by 75, we get 1 and a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 75 from 97 to get 22.
Grab the next digit (7) from the dividend, add it to 22, then carry on: 227 / 75

Advancing to step 3:
When dividing 227 by 75, we get 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 2 after subtracting 225 from 227.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 75

Step 4:
21 divided by 75 is 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 130.0
If we take 0 away from 21, we end up with 21.
Grab the next digit (7) from the dividend, add it to 21, then carry on: 217 / 75

Moving on to step 5:
The number 75 fits into 217 2 times, leaving a remainder of 67.
The number 2 becomes the next digit in our result. 
Result so far: 1302.0
If we subtract 150 from 217, we get 67.
Include the next digit (8) from the dividend after 67, then repeat: 678 / 75

Moving on to step 6:
If we divide 678 by 75, we get 9 and a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 13029.0
The remainder is 3 after subtracting 675 from 678.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
The number 75 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 13029.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
75 goes into 300 4 times with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 13029.04
If we subtract 300 from 300, we get 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:
75 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 13029.04
The remainder is 0 after subtracting 0 from 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 10:
75 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 13029.04
Subtracting 0 from 0 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.

Our division results in 13029.04 with a remaining 0.0.
