571820 ÷ 65 
The aim is to understand the frequency of 65 in 571820.

Let's proceed to step 1:
The number 65 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 65

Step 2:
65 can be fit into 57 0 times, resulting in a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Grab the next digit (1) from the dividend, add it to 57, then carry on: 571 / 65

Advancing to step 3:
65 goes into 571 8 times with a remainder of 51.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 520 from 571, we get 51.
Grab the next digit (8) from the dividend, add it to 51, then carry on: 518 / 65

On to step 4:
The number 65 fits into 518 7 times, leaving a remainder of 63.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
If we subtract 455 from 518, we get 63.
Include the next digit (2) from the dividend after 63, then repeat: 632 / 65

Advancing to step 5:
The number 65 fits into 632 9 times, leaving a remainder of 47.
Record the quotient 9 as the next digit in the result. 
Result so far: 879.0
Subtract 585 from 632 to get 47.
Include the next digit (0) from the dividend after 47, then repeat: 470 / 65

Going ahead to step 6:
65 can be fit into 470 7 times, resulting in a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 8797.0
Deduct 455 from 470 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
150 divided by 65 is 2 with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 8797.2
Subtracting 130 from 150 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
200 divided by 65 is 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 8797.23
If we take 195 away from 200, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
When dividing 50 by 65, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 8797.23
If we take 0 away from 50, 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.

On to step 10:
65 goes into 500 7 times with a remainder of 45.
Put 7 as the next digit of the answer. 
Result so far: 8797.2307
Subtract 455 from 500 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 11:
If we divide 450 by 65, we get 6 and a remainder of 60.
The next digit of our result is 6. 
Result so far: 8797.23076
Subtract 390 from 450 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 12:
65 goes into 600 9 times with a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 8797.230769
Subtract 585 from 600 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 13:
The number 65 fits into 150 2 times, leaving a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 8797.2307692
Deduct 130 from 150 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
200 divided by 65 is 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 8797.23076923
If we take 195 away from 200, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 8797.23076923 and a remainder of 5e-09.
