988109 ÷ 65 
The aim is to understand the frequency of 65 in 988109.

Let's proceed to step 1:
65 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 65

Step 2:
98 divided by 65 is 1 with a remainder of 33.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 65 from 98 to get 33.
Fetch the next digit (8) from the dividend, attach it to 33 and continue: 338 / 65

Going ahead to step 3:
65 can be fit into 338 5 times, resulting in a remainder of 13.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 325 from 338 and we're left with 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 65

Moving on to step 4:
131 divided by 65 is 2 with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 152.0
Deduct 130 from 131 and we're left with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 65

Step 5:
65 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 1520.0
If we subtract 0 from 10, we get 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 65

Step 6:
65 can be fit into 109 1 times, resulting in a remainder of 44.
Use 1 as the next digit of our solution. 
Result so far: 15201.0
If we take 65 away from 109, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 7:
65 can be fit into 440 6 times, resulting in a remainder of 50.
The next digit of our result is 6. 
Result so far: 15201.6
Subtracting 390 from 440 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
65 goes into 500 7 times with a remainder of 45.
The next digit of our result is 7. 
Result so far: 15201.67
The remainder is 45 after subtracting 455 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 9:
When dividing 450 by 65, we get 6 with a remainder of 60.
The next digit of our result is 6. 
Result so far: 15201.676
If we subtract 390 from 450, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 10:
65 goes into 600 9 times with a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 15201.6769
Subtract 585 from 600 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 11:
If we divide 150 by 65, we get 2 and a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 15201.67692
Subtracting 130 from 150 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
When dividing 200 by 65, we get 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 15201.676923
If we subtract 195 from 200, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 13:
50 divided by 65 is 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 15201.676923
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 14:
When dividing 500 by 65, we get 7 with a remainder of 45.
Put 7 as the next digit of the answer. 
Result so far: 15201.67692307
Deduct 455 from 500 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

After the division, we end up with 15201.67692307 and a remainder of 4.5e-08.
