We look at the division of 97591669 by 975 
The aim is to understand the frequency of 975 in 97591669.

Advancing to step 1:
The number 975 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
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 / 975

Step 2:
97 divided by 975 is 0 with a remainder of 97.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 97 leaves us with 97.
Grab the next digit (5) from the dividend, add it to 97, then carry on: 975 / 975

Advancing to step 3:
975 goes into 975 1 times with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 975 from 975 and we're left with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 975

Advancing to step 4:
When dividing 9 by 975, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 9, we get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 975

Advancing to step 5:
91 divided by 975 is 0 with a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 100.0
If we take 0 away from 91, we end up with 91.
Take the next digit (6) from the dividend and append it to 91, then repeat: 916 / 975

Going ahead to step 6:
975 goes into 916 0 times with a remainder of 916.
Put 0 as the next digit of the answer. 
Result so far: 1000.0
Subtract 0 from 916 to get 916.
Take the next digit (6) from the dividend and append it to 916, then repeat: 9166 / 975

Let's proceed to step 7:
If we divide 9166 by 975, we get 9 and a remainder of 391.
Record the quotient 9 as the next digit in the result. 
Result so far: 10009.0
Subtracting 8775 from 9166 leaves us with 391.
Grab the next digit (9) from the dividend, add it to 391, then carry on: 3919 / 975

Moving on to step 8:
When dividing 3919 by 975, we get 4 with a remainder of 19.
The number 4 becomes the next digit in our result. 
Result so far: 100094.0
The remainder is 19 after subtracting 3900 from 3919.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 9:
190 divided by 975 is 0 with a remainder of 190.
Write down 0 as next digit of the result. 
Result so far: 100094.0
If we take 0 away from 190, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 10:
If we divide 1900 by 975, we get 1 and a remainder of 925.
Write down 1 as next digit of the result. 
Result so far: 100094.01
The remainder is 925 after subtracting 975 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9250, and continue the process.

Moving on to step 11:
If we divide 9250 by 975, we get 9 and a remainder of 475.
The number 9 becomes the next digit in our result. 
Result so far: 100094.019
Subtracting 8775 from 9250 leaves us with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Step 12:
If we divide 4750 by 975, we get 4 and a remainder of 850.
The next digit of our result is 4. 
Result so far: 100094.0194
If we subtract 3900 from 4750, we get 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8500, and continue the process.

On to step 13:
975 goes into 8500 8 times with a remainder of 700.
Use 8 as the next digit of our solution. 
Result so far: 100094.01948
Subtracting 7800 from 8500 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Step 14:
When dividing 7000 by 975, we get 7 with a remainder of 175.
Use 7 as the next digit of our solution. 
Result so far: 100094.019487
If we subtract 6825 from 7000, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Step 15:
1750 divided by 975 is 1 with a remainder of 775.
Use 1 as the next digit of our solution. 
Result so far: 100094.0194871
Subtracting 975 from 1750 leaves us with 775.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7750, and continue the process.

Advancing to step 16:
The number 975 fits into 7750 7 times, leaving a remainder of 925.
Use 7 as the next digit of our solution. 
Result so far: 100094.01948717
Subtracting 6825 from 7750 leaves us with 925.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9250, and continue the process.

The final result is 100094.01948717 with a remainder of 9.25e-07.
