We look at the division of 258470 by 65 
Let's see how many times 65 fits into 258470.

On to step 1:
65 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 65

Moving on to step 2:
If we divide 25 by 65, we get 0 and a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Bring next digit (8) of the dividend behind the 25 and repeat the process: 258 / 65

Going ahead to step 3:
If we divide 258 by 65, we get 3 and a remainder of 63.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 63 after subtracting 195 from 258.
Take the next digit (4) from the dividend and append it to 63, then repeat: 634 / 65

Advancing to step 4:
The number 65 fits into 634 9 times, leaving a remainder of 49.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
The remainder is 49 after subtracting 585 from 634.
Include the next digit (7) from the dividend after 49, then repeat: 497 / 65

On to step 5:
If we divide 497 by 65, we get 7 and a remainder of 42.
The number 7 becomes the next digit in our result. 
Result so far: 397.0
Subtracting 455 from 497 leaves us with 42.
Append the next digit (0) from the dividend to 42 and continue with: 420 / 65

Step 6:
The number 65 fits into 420 6 times, leaving a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 3976.0
If we take 390 away from 420, we end up 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.

Step 7:
300 divided by 65 is 4 with a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 3976.4
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.

Let's proceed to step 8:
65 can be fit into 400 6 times, resulting in a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 3976.46
If we take 390 away from 400, we end up 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.

Moving on to step 9:
100 divided by 65 is 1 with a remainder of 35.
The next digit of our result is 1. 
Result so far: 3976.461
Subtract 65 from 100 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.

Moving on to step 10:
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: 3976.4615
Subtracting 325 from 350 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.

Let's proceed to step 11:
65 can be fit into 250 3 times, resulting in a remainder of 55.
Use 3 as the next digit of our solution. 
Result so far: 3976.46153
Subtract 195 from 250 to 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 12:
When dividing 550 by 65, we get 8 with a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 3976.461538
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.

Going ahead to step 13:
65 goes into 300 4 times with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 3976.4615384
If we take 260 away from 300, we end up 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.

Let's proceed to step 14:
65 can be fit into 400 6 times, resulting in a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 3976.46153846
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.

The final result is 3976.46153846 with a remainder of 1e-08.
