We're dividing 491620 by 65 
The aim is to understand the frequency of 65 in 491620.

Going ahead to step 1:
If we divide 4 by 65, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 65

Moving on to step 2:
The number 65 fits into 49 0 times, leaving a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 49 leaves us with 49.
Append the next digit (1) from the dividend to 49 and continue with: 491 / 65

Step 3:
65 goes into 491 7 times with a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 455 from 491 and we're left with 36.
Include the next digit (6) from the dividend after 36, then repeat: 366 / 65

On to step 4:
When dividing 366 by 65, we get 5 with a remainder of 41.
Write down 5 as next digit of the result. 
Result so far: 75.0
If we take 325 away from 366, we end up with 41.
Append the next digit (2) from the dividend to 41 and continue with: 412 / 65

Let's proceed to step 5:
412 divided by 65 is 6 with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 756.0
Deduct 390 from 412 and we're left with 22.
Grab the next digit (0) from the dividend, add it to 22, then carry on: 220 / 65

Going ahead to step 6:
65 goes into 220 3 times with a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 7563.0
Subtracting 195 from 220 leaves us with 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 7:
If we divide 250 by 65, we get 3 and a remainder of 55.
Use 3 as the next digit of our solution. 
Result so far: 7563.3
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.

Let's proceed to step 8:
When dividing 550 by 65, we get 8 with a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 7563.38
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.

Going ahead to step 9:
65 can be fit into 300 4 times, resulting in a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 7563.384
Deduct 260 from 300 and we're left 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:
When dividing 400 by 65, we get 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 7563.3846
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 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: 7563.38461
Subtracting 65 from 100 leaves us 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.

On 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: 7563.384615
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.

Advancing to step 13:
250 divided by 65 is 3 with a remainder of 55.
The next digit of our result is 3. 
Result so far: 7563.3846153
If we subtract 195 from 250, we get 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:
65 goes into 550 8 times with a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 7563.38461538
Deduct 520 from 550 and we're left 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.

Our division results in 7563.38461538 with a remaining 3e-08.
