We're dividing 75300770 by 565 
The aim is to understand the frequency of 565 in 75300770.

Going ahead to step 1:
When dividing 7 by 565, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 565

On to step 2:
If we divide 75 by 565, we get 0 and a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Grab the next digit (3) from the dividend, add it to 75, then carry on: 753 / 565

Moving on to step 3:
753 divided by 565 is 1 with a remainder of 188.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 565 from 753 and we're left with 188.
Take the next digit (0) from the dividend and append it to 188, then repeat: 1880 / 565

Advancing to step 4:
The number 565 fits into 1880 3 times, leaving a remainder of 185.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 1695 away from 1880, we end up with 185.
Bring next digit (0) of the dividend behind the 185 and repeat the process: 1850 / 565

On to step 5:
The number 565 fits into 1850 3 times, leaving a remainder of 155.
The number 3 becomes the next digit in our result. 
Result so far: 133.0
If we subtract 1695 from 1850, we get 155.
Append the next digit (7) from the dividend to 155 and continue with: 1557 / 565

Step 6:
The number 565 fits into 1557 2 times, leaving a remainder of 427.
Write down 2 as next digit of the result. 
Result so far: 1332.0
If we subtract 1130 from 1557, we get 427.
Bring next digit (7) of the dividend behind the 427 and repeat the process: 4277 / 565

On to step 7:
When dividing 4277 by 565, we get 7 with a remainder of 322.
Put 7 as the next digit of the answer. 
Result so far: 13327.0
Subtract 3955 from 4277 to get 322.
Bring next digit (0) of the dividend behind the 322 and repeat the process: 3220 / 565

Let's proceed to step 8:
565 goes into 3220 5 times with a remainder of 395.
The number 5 becomes the next digit in our result. 
Result so far: 133275.0
Deduct 2825 from 3220 and we're left with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Going ahead to step 9:
When dividing 3950 by 565, we get 6 with a remainder of 560.
Write down 6 as next digit of the result. 
Result so far: 133275.6
Subtracting 3390 from 3950 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 10:
565 goes into 5600 9 times with a remainder of 515.
Put 9 as the next digit of the answer. 
Result so far: 133275.69
If we take 5085 away from 5600, we end up with 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Advancing to step 11:
565 can be fit into 5150 9 times, resulting in a remainder of 65.
Write down 9 as next digit of the result. 
Result so far: 133275.699
The remainder is 65 after subtracting 5085 from 5150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

After the division, we end up with 133275.699 and a remainder of 0.0065.
