We look at the division of 11503791 by 575 
The aim is to understand the frequency of 575 in 11503791.

Going ahead to step 1:
The number 575 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 575

Let's proceed to step 2:
575 can be fit into 11 0 times, resulting in a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 11 and we're left with 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 575

Advancing to step 3:
When dividing 115 by 575, we get 0 with a remainder of 115.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 115 to get 115.
Grab the next digit (0) from the dividend, add it to 115, then carry on: 1150 / 575

Going ahead to step 4:
575 can be fit into 1150 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 1150 away from 1150, we end up with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 575

On to step 5:
When dividing 3 by 575, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we subtract 0 from 3, we get 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 575

Step 6:
575 goes into 37 0 times with a remainder of 37.
The next digit of our result is 0. 
Result so far: 200.0
Deduct 0 from 37 and we're left with 37.
Include the next digit (9) from the dividend after 37, then repeat: 379 / 575

Let's proceed to step 7:
If we divide 379 by 575, we get 0 and a remainder of 379.
The number 0 becomes the next digit in our result. 
Result so far: 2000.0
Subtract 0 from 379 to get 379.
Include the next digit (1) from the dividend after 379, then repeat: 3791 / 575

Going ahead to step 8:
If we divide 3791 by 575, we get 6 and a remainder of 341.
Record the quotient 6 as the next digit in the result. 
Result so far: 20006.0
If we subtract 3450 from 3791, we get 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Going ahead to step 9:
575 goes into 3410 5 times with a remainder of 535.
Use 5 as the next digit of our solution. 
Result so far: 20006.5
Subtracting 2875 from 3410 leaves us with 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Moving on to step 10:
If we divide 5350 by 575, we get 9 and a remainder of 175.
The next digit of our result is 9. 
Result so far: 20006.59
The remainder is 175 after subtracting 5175 from 5350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 11:
When dividing 1750 by 575, we get 3 with a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 20006.593
If we subtract 1725 from 1750, we get 25.
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 12:
The number 575 fits into 250 0 times, leaving a remainder of 250.
Use 0 as the next digit of our solution. 
Result so far: 20006.593
Subtracting 0 from 250 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 13:
If we divide 2500 by 575, we get 4 and a remainder of 200.
Record the quotient 4 as the next digit in the result. 
Result so far: 20006.59304
The remainder is 200 after subtracting 2300 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 14:
2000 divided by 575 is 3 with a remainder of 275.
Put 3 as the next digit of the answer. 
Result so far: 20006.593043
If we take 1725 away from 2000, we end up 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.

On to step 15:
When dividing 2750 by 575, we get 4 with a remainder of 450.
The number 4 becomes the next digit in our result. 
Result so far: 20006.5930434
If we subtract 2300 from 2750, we get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Moving on to step 16:
4500 divided by 575 is 7 with a remainder of 475.
Write down 7 as next digit of the result. 
Result so far: 20006.59304347
The remainder is 475 after subtracting 4025 from 4500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

The final result is 20006.59304347 with a remainder of 4.75e-07.
