We divide 520569 by 65
The aim is to understand the frequency of 65 in 520569.

Step 1:
5 divided by 65 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 65

Step 2:
If we divide 52 by 65, we get 0 and a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Bring next digit (0) of the dividend behind the 52 and repeat the process: 520 / 65

Let's proceed to step 3:
65 can be fit into 520 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 520 from 520 leaves us with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 65

On to step 4:
65 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 65

Step 5:
If we divide 56 by 65, we get 0 and a remainder of 56.
The number 0 becomes the next digit in our result. 
Result so far: 800.0
If we take 0 away from 56, we end up with 56.
Include the next digit (9) from the dividend after 56, then repeat: 569 / 65

Step 6:
When dividing 569 by 65, we get 8 with a remainder of 49.
Put 8 as the next digit of the answer. 
Result so far: 8008.0
Deduct 520 from 569 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 7:
65 can be fit into 490 7 times, resulting in a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 8008.7
Subtract 455 from 490 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 8:
65 can be fit into 350 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 8008.75
Deduct 325 from 350 and we're left 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.

Advancing to step 9:
The number 65 fits into 250 3 times, leaving a remainder of 55.
The number 3 becomes the next digit in our result. 
Result so far: 8008.753
Subtracting 195 from 250 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 10:
The number 65 fits into 550 8 times, leaving a remainder of 30.
The next digit of our result is 8. 
Result so far: 8008.7538
If we subtract 520 from 550, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
When dividing 300 by 65, we get 4 with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 8008.75384
Subtract 260 from 300 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
The number 65 fits into 400 6 times, leaving a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 8008.753846
If we subtract 390 from 400, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
65 can be fit into 100 1 times, resulting in a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 8008.7538461
The remainder is 35 after subtracting 65 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 14:
The number 65 fits into 350 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 8008.75384615
Subtract 325 from 350 to 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.

After the division, we end up with 8008.75384615 and a remainder of 2.5e-08.
