520381 ÷ 65 
The aim is to understand the frequency of 65 in 520381.

On to step 1:
65 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 65

On to step 2:
If we divide 52 by 65, we get 0 and a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Append the next digit (0) from the dividend to 52 and continue with: 520 / 65

Advancing to step 3:
65 goes into 520 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 520 from 520 and we're left with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 65

Let's proceed to step 4:
3 divided by 65 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 80.0
Subtract 0 from 3 to get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 65

Step 5:
65 goes into 38 0 times with a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 800.0
Subtract 0 from 38 to get 38.
Fetch the next digit (1) from the dividend, attach it to 38 and continue: 381 / 65

Advancing to step 6:
If we divide 381 by 65, we get 5 and a remainder of 56.
Put 5 as the next digit of the answer. 
Result so far: 8005.0
The remainder is 56 after subtracting 325 from 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 7:
If we divide 560 by 65, we get 8 and a remainder of 40.
The next digit of our result is 8. 
Result so far: 8005.8
If we take 520 away from 560, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
65 can be fit into 400 6 times, resulting in a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 8005.86
Subtracting 390 from 400 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
The number 65 fits into 100 1 times, leaving a remainder of 35.
The next digit of our result is 1. 
Result so far: 8005.861
If we take 65 away from 100, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 10:
350 divided by 65 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 8005.8615
If we subtract 325 from 350, 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.

Let's proceed to step 11:
65 can be fit into 250 3 times, resulting in a remainder of 55.
Record the quotient 3 as the next digit in the result. 
Result so far: 8005.86153
Subtract 195 from 250 to get 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 12:
When dividing 550 by 65, we get 8 with a remainder of 30.
Put 8 as the next digit of the answer. 
Result so far: 8005.861538
The remainder is 30 after subtracting 520 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 13:
65 can be fit into 300 4 times, resulting in a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 8005.8615384
The remainder is 40 after subtracting 260 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 14:
400 divided by 65 is 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 8005.86153846
Subtract 390 from 400 to 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.

In conclusion, the division gives 8005.86153846 with a balance of 1e-08.
