We're dividing 778215 by 65 
The aim is to understand the frequency of 65 in 778215.

On to step 1:
65 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 65

Step 2:
65 can be fit into 77 1 times, resulting in a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 65 from 77 and we're left with 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 65

Moving on to step 3:
If we divide 128 by 65, we get 1 and a remainder of 63.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 65 from 128 and we're left with 63.
Take the next digit (2) from the dividend and append it to 63, then repeat: 632 / 65

Going ahead to step 4:
When dividing 632 by 65, we get 9 with a remainder of 47.
The number 9 becomes the next digit in our result. 
Result so far: 119.0
Subtract 585 from 632 to get 47.
Append the next digit (1) from the dividend to 47 and continue with: 471 / 65

On to step 5:
When dividing 471 by 65, we get 7 with a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 1197.0
If we take 455 away from 471, we end up with 16.
Include the next digit (5) from the dividend after 16, then repeat: 165 / 65

Let's proceed to step 6:
65 goes into 165 2 times with a remainder of 35.
The next digit of our result is 2. 
Result so far: 11972.0
Subtract 130 from 165 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 7:
65 goes into 350 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 11972.5
The remainder is 25 after subtracting 325 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 8:
When dividing 250 by 65, we get 3 with a remainder of 55.
Put 3 as the next digit of the answer. 
Result so far: 11972.53
If we take 195 away from 250, we end up 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.

Moving on to step 9:
If we divide 550 by 65, we get 8 and a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 11972.538
Subtract 520 from 550 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
The number 65 fits into 300 4 times, leaving a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 11972.5384
If we subtract 260 from 300, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
65 goes into 400 6 times with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 11972.53846
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.

On to step 12:
65 can be fit into 100 1 times, resulting in a remainder of 35.
Put 1 as the next digit of the answer. 
Result so far: 11972.538461
The remainder is 35 after subtracting 65 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 13:
When dividing 350 by 65, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 11972.5384615
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.

On to step 14:
When dividing 250 by 65, we get 3 with a remainder of 55.
The number 3 becomes the next digit in our result. 
Result so far: 11972.53846153
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.

The final outcome is 11972.53846153, with a leftover of 5.5e-08.
