402471 ÷ 65 
The aim is to understand the frequency of 65 in 402471.

Let's proceed to step 1:
4 divided by 65 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 65

Moving on to step 2:
When dividing 40 by 65, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Bring next digit (2) of the dividend behind the 40 and repeat the process: 402 / 65

On to step 3:
402 divided by 65 is 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 390 away from 402, we end up with 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 65

Moving on to step 4:
If we divide 124 by 65, we get 1 and a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 61.0
Subtracting 65 from 124 leaves us with 59.
Include the next digit (7) from the dividend after 59, then repeat: 597 / 65

Advancing to step 5:
65 goes into 597 9 times with a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 619.0
Subtract 585 from 597 to get 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 65

Advancing to step 6:
When dividing 121 by 65, we get 1 with a remainder of 56.
The next digit of our result is 1. 
Result so far: 6191.0
If we take 65 away from 121, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 7:
The number 65 fits into 560 8 times, leaving a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 6191.8
If we subtract 520 from 560, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
If we divide 400 by 65, we get 6 and a remainder of 10.
The next digit of our result is 6. 
Result so far: 6191.86
Subtract 390 from 400 to 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.

Moving on to step 9:
If we divide 100 by 65, we get 1 and a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 6191.861
If we take 65 away from 100, we end up with 35.
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 10:
If we divide 350 by 65, we get 5 and a remainder of 25.
The next digit of our result is 5. 
Result so far: 6191.8615
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.

Step 11:
The number 65 fits into 250 3 times, leaving a remainder of 55.
The number 3 becomes the next digit in our result. 
Result so far: 6191.86153
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.

Step 12:
65 can be fit into 550 8 times, resulting in a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 6191.861538
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.

Moving on to step 13:
If we divide 300 by 65, we get 4 and a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 6191.8615384
If we take 260 away from 300, we end up 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.

Moving on to step 14:
If we divide 400 by 65, we get 6 and a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 6191.86153846
Subtracting 390 from 400 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 6191.86153846 with a balance of 1e-08.
