77774681 ÷ 575 
The aim is to understand the frequency of 575 in 77774681.

Let's proceed to step 1:
7 divided by 575 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 575

Advancing to step 2:
The number 575 fits into 77 0 times, leaving a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Include the next digit (7) from the dividend after 77, then repeat: 777 / 575

On to step 3:
777 divided by 575 is 1 with a remainder of 202.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 202 after subtracting 575 from 777.
Take the next digit (7) from the dividend and append it to 202, then repeat: 2027 / 575

Going ahead to step 4:
When dividing 2027 by 575, we get 3 with a remainder of 302.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 1725 from 2027 leaves us with 302.
Append the next digit (4) from the dividend to 302 and continue with: 3024 / 575

Let's proceed to step 5:
The number 575 fits into 3024 5 times, leaving a remainder of 149.
The number 5 becomes the next digit in our result. 
Result so far: 135.0
The remainder is 149 after subtracting 2875 from 3024.
Include the next digit (6) from the dividend after 149, then repeat: 1496 / 575

Step 6:
1496 divided by 575 is 2 with a remainder of 346.
The number 2 becomes the next digit in our result. 
Result so far: 1352.0
If we subtract 1150 from 1496, we get 346.
Bring next digit (8) of the dividend behind the 346 and repeat the process: 3468 / 575

Advancing to step 7:
If we divide 3468 by 575, we get 6 and a remainder of 18.
The next digit of our result is 6. 
Result so far: 13526.0
Subtract 3450 from 3468 to get 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 575

Going ahead to step 8:
575 goes into 181 0 times with a remainder of 181.
Put 0 as the next digit of the answer. 
Result so far: 135260.0
If we subtract 0 from 181, we get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Going ahead to step 9:
575 goes into 1810 3 times with a remainder of 85.
Use 3 as the next digit of our solution. 
Result so far: 135260.3
Subtracting 1725 from 1810 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 10:
575 can be fit into 850 1 times, resulting in a remainder of 275.
Use 1 as the next digit of our solution. 
Result so far: 135260.31
If we subtract 575 from 850, we get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Going ahead to step 11:
If we divide 2750 by 575, we get 4 and a remainder of 450.
Record the quotient 4 as the next digit in the result. 
Result so far: 135260.314
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.

Step 12:
575 goes into 4500 7 times with a remainder of 475.
Put 7 as the next digit of the answer. 
Result so far: 135260.3147
Subtracting 4025 from 4500 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.

On to step 13:
575 goes into 4750 8 times with a remainder of 150.
Use 8 as the next digit of our solution. 
Result so far: 135260.31478
Subtracting 4600 from 4750 leaves us 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.

Moving on to step 14:
The number 575 fits into 1500 2 times, leaving a remainder of 350.
Put 2 as the next digit of the answer. 
Result so far: 135260.314782
The remainder is 350 after subtracting 1150 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Moving on to step 15:
When dividing 3500 by 575, we get 6 with a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 135260.3147826
If we take 3450 away from 3500, 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.

Step 16:
500 divided by 575 is 0 with a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 135260.3147826
Deduct 0 from 500 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

After the division, we end up with 135260.3147826 and a remainder of 5e-07.
