We're dividing 65514166 by 259 
The aim is to understand the frequency of 259 in 65514166.

Moving on to step 1:
If we divide 6 by 259, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 259

Advancing to step 2:
259 goes into 65 0 times with a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 65 after subtracting 0 from 65.
Fetch the next digit (5) from the dividend, attach it to 65 and continue: 655 / 259

Let's proceed to step 3:
259 goes into 655 2 times with a remainder of 137.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 518 from 655 and we're left with 137.
Append the next digit (1) from the dividend to 137 and continue with: 1371 / 259

Step 4:
259 can be fit into 1371 5 times, resulting in a remainder of 76.
The next digit of our result is 5. 
Result so far: 25.0
If we subtract 1295 from 1371, we get 76.
Include the next digit (4) from the dividend after 76, then repeat: 764 / 259

Going ahead to step 5:
259 goes into 764 2 times with a remainder of 246.
Put 2 as the next digit of the answer. 
Result so far: 252.0
If we subtract 518 from 764, we get 246.
Bring next digit (1) of the dividend behind the 246 and repeat the process: 2461 / 259

Step 6:
The number 259 fits into 2461 9 times, leaving a remainder of 130.
The next digit of our result is 9. 
Result so far: 2529.0
The remainder is 130 after subtracting 2331 from 2461.
Grab the next digit (6) from the dividend, add it to 130, then carry on: 1306 / 259

On to step 7:
1306 divided by 259 is 5 with a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 25295.0
Deduct 1295 from 1306 and we're left with 11.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 259

Going ahead to step 8:
The number 259 fits into 116 0 times, leaving a remainder of 116.
The next digit of our result is 0. 
Result so far: 252950.0
Subtracting 0 from 116 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Advancing to step 9:
259 can be fit into 1160 4 times, resulting in a remainder of 124.
The number 4 becomes the next digit in our result. 
Result so far: 252950.4
Subtract 1036 from 1160 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Going ahead to step 10:
If we divide 1240 by 259, we get 4 and a remainder of 204.
Use 4 as the next digit of our solution. 
Result so far: 252950.44
Subtract 1036 from 1240 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

The quotient of the division is 252950.44, and the remainder is 0.204.
