We look at the division of 81022 by 65 
The aim is to understand the frequency of 65 in 81022.

Moving on to step 1:
If we divide 8 by 65, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 65

Advancing to step 2:
If we divide 81 by 65, we get 1 and a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 65 away from 81, we end up with 16.
Take the next digit (0) from the dividend and append it to 16, then repeat: 160 / 65

On to step 3:
When dividing 160 by 65, we get 2 with a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 130 from 160, we get 30.
Append the next digit (2) from the dividend to 30 and continue with: 302 / 65

On to step 4:
65 can be fit into 302 4 times, resulting in a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 124.0
The remainder is 42 after subtracting 260 from 302.
Include the next digit (2) from the dividend after 42, then repeat: 422 / 65

Advancing to step 5:
When dividing 422 by 65, we get 6 with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 1246.0
Subtract 390 from 422 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 6:
If we divide 320 by 65, we get 4 and a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 1246.4
Deduct 260 from 320 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 7:
When dividing 600 by 65, we get 9 with a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 1246.49
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.

Step 8:
The number 65 fits into 150 2 times, leaving a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 1246.492
If we take 130 away from 150, we end up 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.

Moving on to step 9:
If we divide 200 by 65, we get 3 and a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 1246.4923
Deduct 195 from 200 and we're left 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.

On to step 10:
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: 1246.4923
The remainder is 50 after subtracting 0 from 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 11:
If we divide 500 by 65, we get 7 and a remainder of 45.
Record the quotient 7 as the next digit in the result. 
Result so far: 1246.492307
Deduct 455 from 500 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 12:
When dividing 450 by 65, we get 6 with a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 1246.4923076
If we subtract 390 from 450, we 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.

Moving on to step 13:
65 goes into 600 9 times with a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 1246.49230769
If we subtract 585 from 600, we 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.

The quotient of the division is 1246.49230769, and the remainder is 1.5e-08.
