We look at the division of 18028148 by 975 
The aim is to understand the frequency of 975 in 18028148.

Advancing to step 1:
If we divide 1 by 975, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 975

Step 2:
The number 975 fits into 18 0 times, leaving a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Take the next digit (0) from the dividend and append it to 18, then repeat: 180 / 975

Going ahead to step 3:
975 can be fit into 180 0 times, resulting in a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 180 after subtracting 0 from 180.
Fetch the next digit (2) from the dividend, attach it to 180 and continue: 1802 / 975

Let's proceed to step 4:
975 goes into 1802 1 times with a remainder of 827.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 975 from 1802 leaves us with 827.
Grab the next digit (8) from the dividend, add it to 827, then carry on: 8278 / 975

On to step 5:
The number 975 fits into 8278 8 times, leaving a remainder of 478.
Put 8 as the next digit of the answer. 
Result so far: 18.0
The remainder is 478 after subtracting 7800 from 8278.
Append the next digit (1) from the dividend to 478 and continue with: 4781 / 975

Moving on to step 6:
4781 divided by 975 is 4 with a remainder of 881.
The number 4 becomes the next digit in our result. 
Result so far: 184.0
Subtracting 3900 from 4781 leaves us with 881.
Take the next digit (4) from the dividend and append it to 881, then repeat: 8814 / 975

Step 7:
When dividing 8814 by 975, we get 9 with a remainder of 39.
The next digit of our result is 9. 
Result so far: 1849.0
If we take 8775 away from 8814, we end up with 39.
Grab the next digit (8) from the dividend, add it to 39, then carry on: 398 / 975

Advancing to step 8:
If we divide 398 by 975, we get 0 and a remainder of 398.
The number 0 becomes the next digit in our result. 
Result so far: 18490.0
If we subtract 0 from 398, we get 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Advancing to step 9:
If we divide 3980 by 975, we get 4 and a remainder of 80.
Use 4 as the next digit of our solution. 
Result so far: 18490.4
Subtract 3900 from 3980 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 10:
800 divided by 975 is 0 with a remainder of 800.
The next digit of our result is 0. 
Result so far: 18490.4
If we subtract 0 from 800, we get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Let's proceed to step 11:
975 goes into 8000 8 times with a remainder of 200.
Record the quotient 8 as the next digit in the result. 
Result so far: 18490.408
Subtract 7800 from 8000 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 12:
If we divide 2000 by 975, we get 2 and a remainder of 50.
Write down 2 as next digit of the result. 
Result so far: 18490.4082
The remainder is 50 after subtracting 1950 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 13:
500 divided by 975 is 0 with a remainder of 500.
Put 0 as the next digit of the answer. 
Result so far: 18490.4082
Subtract 0 from 500 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

On to step 14:
If we divide 5000 by 975, we get 5 and a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 18490.408205
If we subtract 4875 from 5000, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 15:
975 can be fit into 1250 1 times, resulting in a remainder of 275.
Put 1 as the next digit of the answer. 
Result so far: 18490.4082051
Subtracting 975 from 1250 leaves us with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Step 16:
When dividing 2750 by 975, we get 2 with a remainder of 800.
Use 2 as the next digit of our solution. 
Result so far: 18490.40820512
If we take 1950 away from 2750, we end up with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

The final outcome is 18490.40820512, with a leftover of 8e-07.
