837934 ÷ 65 
The aim is to understand the frequency of 65 in 837934.

On to step 1:
The number 65 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 65

Let's proceed to step 2:
83 divided by 65 is 1 with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 65 away from 83, we end up with 18.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 65

On to step 3:
The number 65 fits into 187 2 times, leaving a remainder of 57.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 130 from 187 leaves us with 57.
Append the next digit (9) from the dividend to 57 and continue with: 579 / 65

Step 4:
65 goes into 579 8 times with a remainder of 59.
Write down 8 as next digit of the result. 
Result so far: 128.0
The remainder is 59 after subtracting 520 from 579.
Fetch the next digit (3) from the dividend, attach it to 59 and continue: 593 / 65

Advancing to step 5:
When dividing 593 by 65, we get 9 with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 1289.0
Deduct 585 from 593 and we're left with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 65

Advancing to step 6:
When dividing 84 by 65, we get 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 12891.0
Subtracting 65 from 84 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 7:
If we divide 190 by 65, we get 2 and a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 12891.2
If we subtract 130 from 190, 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.

Going ahead to step 8:
The number 65 fits into 600 9 times, leaving a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 12891.29
Subtracting 585 from 600 leaves us 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.

Advancing to step 9:
When dividing 150 by 65, we get 2 with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 12891.292
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.

Advancing to step 10:
200 divided by 65 is 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 12891.2923
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 11:
The number 65 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 12891.2923
If we take 0 away from 50, we end up 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.

Let's proceed to step 12:
65 can be fit into 500 7 times, resulting in a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 12891.292307
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.

Going ahead to step 13:
If we divide 450 by 65, we get 6 and a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 12891.2923076
Deduct 390 from 450 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 14:
600 divided by 65 is 9 with a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 12891.29230769
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.

The final outcome is 12891.29230769, with a leftover of 1.5e-08.
