4577226 divided by 575 
The aim is to understand the frequency of 575 in 4577226.

Step 1:
When dividing 4 by 575, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 575

Let's proceed to step 2:
575 can be fit into 45 0 times, resulting in a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Fetch the next digit (7) from the dividend, attach it to 45 and continue: 457 / 575

On to step 3:
The number 575 fits into 457 0 times, leaving a remainder of 457.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 457 and we're left with 457.
Bring next digit (7) of the dividend behind the 457 and repeat the process: 4577 / 575

Step 4:
575 can be fit into 4577 7 times, resulting in a remainder of 552.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 4025 away from 4577, we end up with 552.
Take the next digit (2) from the dividend and append it to 552, then repeat: 5522 / 575

Let's proceed to step 5:
When dividing 5522 by 575, we get 9 with a remainder of 347.
Use 9 as the next digit of our solution. 
Result so far: 79.0
Subtract 5175 from 5522 to get 347.
Append the next digit (2) from the dividend to 347 and continue with: 3472 / 575

Advancing to step 6:
3472 divided by 575 is 6 with a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 796.0
Subtract 3450 from 3472 to get 22.
Append the next digit (6) from the dividend to 22 and continue with: 226 / 575

On to step 7:
226 divided by 575 is 0 with a remainder of 226.
Write down 0 as next digit of the result. 
Result so far: 7960.0
If we subtract 0 from 226, we get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

On to step 8:
When dividing 2260 by 575, we get 3 with a remainder of 535.
Put 3 as the next digit of the answer. 
Result so far: 7960.3
The remainder is 535 after subtracting 1725 from 2260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

On to step 9:
575 goes into 5350 9 times with a remainder of 175.
The next digit of our result is 9. 
Result so far: 7960.39
Subtracting 5175 from 5350 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Let's proceed to step 10:
When dividing 1750 by 575, we get 3 with a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 7960.393
If we take 1725 away from 1750, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 11:
575 can be fit into 250 0 times, resulting in a remainder of 250.
Put 0 as the next digit of the answer. 
Result so far: 7960.393
The remainder is 250 after subtracting 0 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 12:
The number 575 fits into 2500 4 times, leaving a remainder of 200.
Put 4 as the next digit of the answer. 
Result so far: 7960.39304
If we take 2300 away from 2500, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 13:
If we divide 2000 by 575, we get 3 and a remainder of 275.
Use 3 as the next digit of our solution. 
Result so far: 7960.393043
The remainder is 275 after subtracting 1725 from 2000.
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 14:
The number 575 fits into 2750 4 times, leaving a remainder of 450.
Put 4 as the next digit of the answer. 
Result so far: 7960.3930434
Subtract 2300 from 2750 to 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.

Let's proceed to step 15:
If we divide 4500 by 575, we get 7 and a remainder of 475.
Use 7 as the next digit of our solution. 
Result so far: 7960.39304347
Deduct 4025 from 4500 and we're left 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.

The final outcome is 7960.39304347, with a leftover of 4.75e-07.
