43994 ÷ 65 
The aim is to understand the frequency of 65 in 43994.

Advancing to step 1:
If we divide 4 by 65, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 65

Let's proceed to step 2:
When dividing 43 by 65, we get 0 with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Include the next digit (9) from the dividend after 43, then repeat: 439 / 65

Moving on to step 3:
The number 65 fits into 439 6 times, leaving a remainder of 49.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 390 from 439 and we're left with 49.
Append the next digit (9) from the dividend to 49 and continue with: 499 / 65

On to step 4:
65 goes into 499 7 times with a remainder of 44.
The next digit of our result is 7. 
Result so far: 67.0
If we subtract 455 from 499, we get 44.
Take the next digit (4) from the dividend and append it to 44, then repeat: 444 / 65

Step 5:
If we divide 444 by 65, we get 6 and a remainder of 54.
The number 6 becomes the next digit in our result. 
Result so far: 676.0
If we take 390 away from 444, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 6:
When dividing 540 by 65, we get 8 with a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 676.8
Deduct 520 from 540 and we're left 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.

Advancing to step 7:
200 divided by 65 is 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 676.83
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.

Advancing to step 8:
When dividing 50 by 65, we get 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 676.83
If we subtract 0 from 50, we 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.

On to step 9:
500 divided by 65 is 7 with a remainder of 45.
Write down 7 as next digit of the result. 
Result so far: 676.8307
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.

Let's proceed to step 10:
450 divided by 65 is 6 with a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 676.83076
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.

Going ahead to step 11:
600 divided by 65 is 9 with a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 676.830769
The remainder is 15 after subtracting 585 from 600.
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 12:
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: 676.8307692
The remainder is 20 after subtracting 130 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
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: 676.83076923
If we take 195 away from 200, we end up 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.

The quotient of the division is 676.83076923, and the remainder is 5e-09.
