We look at the division of 743270 by 65 
The aim is to understand the frequency of 65 in 743270.

Step 1:
When dividing 7 by 65, 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.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 65

Going ahead to step 2:
The number 65 fits into 74 1 times, leaving a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 65 from 74 to get 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 65

Step 3:
93 divided by 65 is 1 with a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 28 after subtracting 65 from 93.
Grab the next digit (2) from the dividend, add it to 28, then carry on: 282 / 65

On to step 4:
282 divided by 65 is 4 with a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 114.0
If we subtract 260 from 282, we get 22.
Append the next digit (7) from the dividend to 22 and continue with: 227 / 65

On to step 5:
227 divided by 65 is 3 with a remainder of 32.
Use 3 as the next digit of our solution. 
Result so far: 1143.0
The remainder is 32 after subtracting 195 from 227.
Append the next digit (0) from the dividend to 32 and continue with: 320 / 65

Step 6:
320 divided by 65 is 4 with a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 11434.0
Subtracting 260 from 320 leaves us 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.

Going ahead to step 7:
The number 65 fits into 600 9 times, leaving a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 11434.9
Subtracting 585 from 600 leaves us 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.

Moving on to step 8:
When dividing 150 by 65, we get 2 with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 11434.92
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.

Moving on to step 9:
If we divide 200 by 65, we get 3 and a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 11434.923
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.

Let's proceed to step 10:
If we divide 50 by 65, we get 0 and a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 11434.923
Subtracting 0 from 50 leaves us 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.

Let's proceed to step 11:
If we divide 500 by 65, we get 7 and a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 11434.92307
The remainder is 45 after subtracting 455 from 500.
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 12:
The number 65 fits into 450 6 times, leaving a remainder of 60.
The next digit of our result is 6. 
Result so far: 11434.923076
The remainder is 60 after subtracting 390 from 450.
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 13:
The number 65 fits into 600 9 times, leaving a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 11434.9230769
The remainder is 15 after subtracting 585 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 14:
The number 65 fits into 150 2 times, leaving a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 11434.92307692
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.

Our division results in 11434.92307692 with a remaining 2e-08.
