Let's divide 443919 by 65
The aim is to understand the frequency of 65 in 443919.

Going ahead to step 1:
If we divide 4 by 65, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 65

Moving on to step 2:
When dividing 44 by 65, we get 0 with a remainder of 44.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 44 after subtracting 0 from 44.
Bring next digit (3) of the dividend behind the 44 and repeat the process: 443 / 65

Advancing to step 3:
65 can be fit into 443 6 times, resulting in a remainder of 53.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 53 after subtracting 390 from 443.
Grab the next digit (9) from the dividend, add it to 53, then carry on: 539 / 65

Step 4:
65 can be fit into 539 8 times, resulting in a remainder of 19.
The number 8 becomes the next digit in our result. 
Result so far: 68.0
The remainder is 19 after subtracting 520 from 539.
Include the next digit (1) from the dividend after 19, then repeat: 191 / 65

Let's proceed to step 5:
If we divide 191 by 65, we get 2 and a remainder of 61.
Record the quotient 2 as the next digit in the result. 
Result so far: 682.0
Deduct 130 from 191 and we're left with 61.
Bring next digit (9) of the dividend behind the 61 and repeat the process: 619 / 65

Going ahead to step 6:
When dividing 619 by 65, we get 9 with a remainder of 34.
The number 9 becomes the next digit in our result. 
Result so far: 6829.0
If we take 585 away from 619, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 7:
65 can be fit into 340 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 6829.5
If we subtract 325 from 340, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
65 goes into 150 2 times with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 6829.52
If we subtract 130 from 150, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
200 divided by 65 is 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 6829.523
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: 6829.523
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.

Advancing to step 11:
The number 65 fits into 500 7 times, leaving a remainder of 45.
Record the quotient 7 as the next digit in the result. 
Result so far: 6829.52307
If we take 455 away from 500, we end up 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.

Going ahead to step 12:
65 can be fit into 450 6 times, resulting in a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 6829.523076
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.

Step 13:
When dividing 600 by 65, we get 9 with a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 6829.5230769
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.

On to step 14:
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: 6829.52307692
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.

The final result is 6829.52307692 with a remainder of 2e-08.
