We look at the division of 42065585 by 65 
The aim is to understand the frequency of 65 in 42065585.

Let's proceed to step 1:
The number 65 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 65

Step 2:
65 can be fit into 42 0 times, resulting in a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Fetch the next digit (0) from the dividend, attach it to 42 and continue: 420 / 65

Advancing to step 3:
If we divide 420 by 65, we get 6 and a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 390 away from 420, we end up with 30.
Fetch the next digit (6) from the dividend, attach it to 30 and continue: 306 / 65

Let's proceed to step 4:
The number 65 fits into 306 4 times, leaving a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 64.0
If we take 260 away from 306, we end up with 46.
Take the next digit (5) from the dividend and append it to 46, then repeat: 465 / 65

Going ahead to step 5:
65 goes into 465 7 times with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 647.0
If we take 455 away from 465, we end up with 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 65

Step 6:
If we divide 105 by 65, we get 1 and a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 6471.0
The remainder is 40 after subtracting 65 from 105.
Append the next digit (8) from the dividend to 40 and continue with: 408 / 65

Advancing to step 7:
408 divided by 65 is 6 with a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 64716.0
If we take 390 away from 408, we end up with 18.
Fetch the next digit (5) from the dividend, attach it to 18 and continue: 185 / 65

Moving on to step 8:
If we divide 185 by 65, we get 2 and a remainder of 55.
The number 2 becomes the next digit in our result. 
Result so far: 647162.0
If we take 130 away from 185, 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 9:
If we divide 550 by 65, we get 8 and a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 647162.8
If we subtract 520 from 550, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
65 goes into 300 4 times with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 647162.84
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.

Advancing to step 11:
65 goes into 400 6 times with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 647162.846
The remainder is 10 after subtracting 390 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 12:
When dividing 100 by 65, we get 1 with a remainder of 35.
The next digit of our result is 1. 
Result so far: 647162.8461
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.

Moving on to step 13:
When dividing 350 by 65, we get 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 647162.84615
The remainder is 25 after subtracting 325 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 14:
When dividing 250 by 65, we get 3 with a remainder of 55.
Use 3 as the next digit of our solution. 
Result so far: 647162.846153
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 15:
If we divide 550 by 65, we get 8 and a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 647162.8461538
Subtract 520 from 550 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 16:
65 goes into 300 4 times with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 647162.84615384
The remainder is 40 after subtracting 260 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 647162.84615384 with a balance of 4e-08.
