78383 ÷ 65 
The aim is to understand the frequency of 65 in 78383.

On to step 1:
When dividing 7 by 65, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 65

Let's proceed to step 2:
The number 65 fits into 78 1 times, leaving a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 65 from 78 to get 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 65

On to step 3:
The number 65 fits into 133 2 times, leaving a remainder of 3.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 130 from 133, we get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 65

Going ahead to step 4:
When dividing 38 by 65, we get 0 with a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 120.0
Subtracting 0 from 38 leaves us with 38.
Append the next digit (3) from the dividend to 38 and continue with: 383 / 65

Step 5:
If we divide 383 by 65, we get 5 and a remainder of 58.
Use 5 as the next digit of our solution. 
Result so far: 1205.0
The remainder is 58 after subtracting 325 from 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 6:
65 goes into 580 8 times with a remainder of 60.
The next digit of our result is 8. 
Result so far: 1205.8
If we subtract 520 from 580, 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 7:
The number 65 fits into 600 9 times, leaving a remainder of 15.
The next digit of our result is 9. 
Result so far: 1205.89
If we take 585 away from 600, we end up 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:
150 divided by 65 is 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 1205.892
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: 1205.8923
Subtract 195 from 200 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 10:
The number 65 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 1205.8923
Subtract 0 from 50 to get 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:
65 goes into 500 7 times with a remainder of 45.
Write down 7 as next digit of the result. 
Result so far: 1205.892307
Subtracting 455 from 500 leaves us 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.

On to step 12:
When dividing 450 by 65, we get 6 with a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 1205.8923076
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.

Advancing to step 13:
If we divide 600 by 65, we get 9 and a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 1205.89230769
If we take 585 away from 600, we end up 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.

After the division, we end up with 1205.89230769 and a remainder of 1.5e-08.
