Let's divide 715880 by 65
The aim is to understand the frequency of 65 in 715880.

Advancing to step 1:
The number 65 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 65

Moving on to step 2:
When dividing 71 by 65, we get 1 with a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 65 from 71 leaves us with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 65

Step 3:
65 divided by 65 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 65 from 65 and we're left with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 65

Going ahead to step 4:
8 divided by 65 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 110.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 65

Let's proceed to step 5:
If we divide 88 by 65, we get 1 and a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 1101.0
Subtracting 65 from 88 leaves us with 23.
Bring next digit (0) of the dividend behind the 23 and repeat the process: 230 / 65

Moving on to step 6:
65 can be fit into 230 3 times, resulting in a remainder of 35.
Write down 3 as next digit of the result. 
Result so far: 11013.0
Subtract 195 from 230 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 7:
The number 65 fits into 350 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 11013.5
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.

Advancing to step 8:
65 goes into 250 3 times with a remainder of 55.
Use 3 as the next digit of our solution. 
Result so far: 11013.53
Deduct 195 from 250 and we're left 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.

On to step 9:
550 divided by 65 is 8 with a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 11013.538
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.

On to step 10:
65 goes into 300 4 times with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 11013.5384
Subtract 260 from 300 to 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.

Let's proceed to step 11:
When dividing 400 by 65, we get 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 11013.53846
Deduct 390 from 400 and we're left 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.

Let's proceed to step 12:
If we divide 100 by 65, we get 1 and a remainder of 35.
The next digit of our result is 1. 
Result so far: 11013.538461
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.

Advancing to step 13:
65 can be fit into 350 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 11013.5384615
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.

Step 14:
65 can be fit into 250 3 times, resulting in a remainder of 55.
The next digit of our result is 3. 
Result so far: 11013.53846153
The remainder is 55 after subtracting 195 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Our division results in 11013.53846153 with a remaining 5.5e-08.
