331915 ÷ 65 
The aim is to understand the frequency of 65 in 331915.

Going ahead to step 1:
If we divide 3 by 65, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 65

Step 2:
If we divide 33 by 65, we get 0 and a remainder of 33.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 33 to get 33.
Grab the next digit (1) from the dividend, add it to 33, then carry on: 331 / 65

On to step 3:
If we divide 331 by 65, we get 5 and a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 325 from 331 and we're left with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 65

Let's proceed to step 4:
If we divide 69 by 65, we get 1 and a remainder of 4.
The next digit of our result is 1. 
Result so far: 51.0
Subtracting 65 from 69 leaves us with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 65

Advancing to step 5:
41 divided by 65 is 0 with a remainder of 41.
Record the quotient 0 as the next digit in the result. 
Result so far: 510.0
If we take 0 away from 41, we end up with 41.
Bring next digit (5) of the dividend behind the 41 and repeat the process: 415 / 65

Moving on to step 6:
65 can be fit into 415 6 times, resulting in a remainder of 25.
Write down 6 as next digit of the result. 
Result so far: 5106.0
The remainder is 25 after subtracting 390 from 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 7:
250 divided by 65 is 3 with a remainder of 55.
Use 3 as the next digit of our solution. 
Result so far: 5106.3
If we take 195 away from 250, we end up 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.

Advancing to step 8:
The number 65 fits into 550 8 times, leaving a remainder of 30.
The next digit of our result is 8. 
Result so far: 5106.38
Subtracting 520 from 550 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
When dividing 300 by 65, we get 4 with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 5106.384
Subtracting 260 from 300 leaves us with 40.
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 10:
65 goes into 400 6 times with a remainder of 10.
The next digit of our result is 6. 
Result so far: 5106.3846
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.

Going ahead to step 11:
If we divide 100 by 65, we get 1 and a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 5106.38461
The remainder is 35 after subtracting 65 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 12:
65 can be fit into 350 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 5106.384615
Subtract 325 from 350 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 13:
250 divided by 65 is 3 with a remainder of 55.
Record the quotient 3 as the next digit in the result. 
Result so far: 5106.3846153
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.

Advancing to step 14:
When dividing 550 by 65, we get 8 with a remainder of 30.
Put 8 as the next digit of the answer. 
Result so far: 5106.38461538
If we take 520 away from 550, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 5106.38461538, with a leftover of 3e-08.
