We're dividing 511227 by 175 
The aim is to understand the frequency of 175 in 511227.

Step 1:
When dividing 5 by 175, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 175

Moving on to step 2:
51 divided by 175 is 0 with a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Bring next digit (1) of the dividend behind the 51 and repeat the process: 511 / 175

On to step 3:
511 divided by 175 is 2 with a remainder of 161.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 350 from 511 to get 161.
Take the next digit (2) from the dividend and append it to 161, then repeat: 1612 / 175

On to step 4:
1612 divided by 175 is 9 with a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 29.0
The remainder is 37 after subtracting 1575 from 1612.
Append the next digit (2) from the dividend to 37 and continue with: 372 / 175

Moving on to step 5:
The number 175 fits into 372 2 times, leaving a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 292.0
Subtracting 350 from 372 leaves us with 22.
Include the next digit (7) from the dividend after 22, then repeat: 227 / 175

On to step 6:
227 divided by 175 is 1 with a remainder of 52.
Record the quotient 1 as the next digit in the result. 
Result so far: 2921.0
Deduct 175 from 227 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 7:
If we divide 520 by 175, we get 2 and a remainder of 170.
The next digit of our result is 2. 
Result so far: 2921.2
If we subtract 350 from 520, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 8:
175 can be fit into 1700 9 times, resulting in a remainder of 125.
The next digit of our result is 9. 
Result so far: 2921.29
The remainder is 125 after subtracting 1575 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 9:
175 can be fit into 1250 7 times, resulting in a remainder of 25.
The number 7 becomes the next digit in our result. 
Result so far: 2921.297
If we subtract 1225 from 1250, 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.

On to step 10:
250 divided by 175 is 1 with a remainder of 75.
The number 1 becomes the next digit in our result. 
Result so far: 2921.2971
If we subtract 175 from 250, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 11:
The number 175 fits into 750 4 times, leaving a remainder of 50.
The number 4 becomes the next digit in our result. 
Result so far: 2921.29714
If we take 700 away from 750, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 12:
The number 175 fits into 500 2 times, leaving a remainder of 150.
The next digit of our result is 2. 
Result so far: 2921.297142
If we take 350 away from 500, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 13:
175 goes into 1500 8 times with a remainder of 100.
Write down 8 as next digit of the result. 
Result so far: 2921.2971428
Subtract 1400 from 1500 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 14:
175 can be fit into 1000 5 times, resulting in a remainder of 125.
The next digit of our result is 5. 
Result so far: 2921.29714285
Deduct 875 from 1000 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

The final result is 2921.29714285 with a remainder of 1.25e-07.
