We look at the division of 77548758 by 65 
The aim is to understand the frequency of 65 in 77548758.

Moving on to step 1:
65 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 65

Let's proceed to step 2:
The number 65 fits into 77 1 times, leaving a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 65 away from 77, we end up with 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 65

On to step 3:
65 can be fit into 125 1 times, resulting in a remainder of 60.
The next digit of our result is 1. 
Result so far: 11.0
Subtracting 65 from 125 leaves us with 60.
Take the next digit (4) from the dividend and append it to 60, then repeat: 604 / 65

On to step 4:
604 divided by 65 is 9 with a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 119.0
If we take 585 away from 604, we end up with 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 65

Let's proceed to step 5:
If we divide 198 by 65, we get 3 and a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 1193.0
If we subtract 195 from 198, we get 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 65

Advancing to step 6:
If we divide 37 by 65, we get 0 and a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 11930.0
If we subtract 0 from 37, we get 37.
Grab the next digit (5) from the dividend, add it to 37, then carry on: 375 / 65

Advancing to step 7:
The number 65 fits into 375 5 times, leaving a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 119305.0
The remainder is 50 after subtracting 325 from 375.
Grab the next digit (8) from the dividend, add it to 50, then carry on: 508 / 65

On to step 8:
If we divide 508 by 65, we get 7 and a remainder of 53.
The next digit of our result is 7. 
Result so far: 1193057.0
Deduct 455 from 508 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 9:
If we divide 530 by 65, we get 8 and a remainder of 10.
The next digit of our result is 8. 
Result so far: 1193057.8
If we subtract 520 from 530, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
If we divide 100 by 65, we get 1 and a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 1193057.81
If we take 65 away from 100, we end up 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.

Advancing to step 11:
When dividing 350 by 65, we get 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 1193057.815
Subtracting 325 from 350 leaves us 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 12:
When dividing 250 by 65, we get 3 with a remainder of 55.
Record the quotient 3 as the next digit in the result. 
Result so far: 1193057.8153
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.

On to step 13:
If we divide 550 by 65, we get 8 and a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 1193057.81538
If we subtract 520 from 550, we 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 14:
The number 65 fits into 300 4 times, leaving a remainder of 40.
The next digit of our result is 4. 
Result so far: 1193057.815384
The remainder is 40 after subtracting 260 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 15:
If we divide 400 by 65, we get 6 and a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 1193057.8153846
If we subtract 390 from 400, we get 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 16:
If we divide 100 by 65, we get 1 and a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 1193057.81538461
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.

After the division, we end up with 1193057.81538461 and a remainder of 3.5e-08.
