We look at the division of 425216 by 65 
The aim is to understand the frequency of 65 in 425216.

Let's proceed to step 1:
The number 65 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 65

Moving on to step 2:
If we divide 42 by 65, we get 0 and a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Include the next digit (5) from the dividend after 42, then repeat: 425 / 65

Let's proceed to step 3:
65 can be fit into 425 6 times, resulting in a remainder of 35.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 390 from 425, we get 35.
Take the next digit (2) from the dividend and append it to 35, then repeat: 352 / 65

Advancing to step 4:
65 can be fit into 352 5 times, resulting in a remainder of 27.
Put 5 as the next digit of the answer. 
Result so far: 65.0
If we subtract 325 from 352, we get 27.
Include the next digit (1) from the dividend after 27, then repeat: 271 / 65

Step 5:
If we divide 271 by 65, we get 4 and a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 654.0
Subtract 260 from 271 to get 11.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 65

Advancing to step 6:
65 can be fit into 116 1 times, resulting in a remainder of 51.
Record the quotient 1 as the next digit in the result. 
Result so far: 6541.0
Subtract 65 from 116 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 7:
65 goes into 510 7 times with a remainder of 55.
Write down 7 as next digit of the result. 
Result so far: 6541.7
If we subtract 455 from 510, we 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.

Advancing to step 8:
550 divided by 65 is 8 with a remainder of 30.
Put 8 as the next digit of the answer. 
Result so far: 6541.78
Deduct 520 from 550 and we're left with 30.
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 9:
The number 65 fits into 300 4 times, leaving a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 6541.784
Deduct 260 from 300 and we're left 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 10:
400 divided by 65 is 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 6541.7846
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.

Step 11:
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: 6541.78461
Subtracting 65 from 100 leaves us 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.

Going ahead to step 12:
65 goes into 350 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 6541.784615
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.

Step 13:
250 divided by 65 is 3 with a remainder of 55.
The number 3 becomes the next digit in our result. 
Result so far: 6541.7846153
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.

Advancing to step 14:
When dividing 550 by 65, we get 8 with a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 6541.78461538
Deduct 520 from 550 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 6541.78461538 with a remainder of 3e-08.
