We look at the division of 258930 by 85 
Let's see how many times 85 fits into 258930.

Advancing to step 1:
The number 85 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 85

Going ahead to step 2:
85 can be fit into 25 0 times, resulting in a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Grab the next digit (8) from the dividend, add it to 25, then carry on: 258 / 85

Moving on to step 3:
258 divided by 85 is 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 255 from 258 leaves us with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 85

Let's proceed to step 4:
39 divided by 85 is 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 30.0
Subtracting 0 from 39 leaves us with 39.
Grab the next digit (3) from the dividend, add it to 39, then carry on: 393 / 85

On to step 5:
When dividing 393 by 85, we get 4 with a remainder of 53.
Record the quotient 4 as the next digit in the result. 
Result so far: 304.0
The remainder is 53 after subtracting 340 from 393.
Include the next digit (0) from the dividend after 53, then repeat: 530 / 85

On to step 6:
85 goes into 530 6 times with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 3046.0
Subtract 510 from 530 to get 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 7:
85 can be fit into 200 2 times, resulting in a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 3046.2
If we take 170 away from 200, 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.

Moving on to step 8:
When dividing 300 by 85, we get 3 with a remainder of 45.
Write down 3 as next digit of the result. 
Result so far: 3046.23
If we take 255 away from 300, we end up 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.

Moving on to step 9:
450 divided by 85 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 3046.235
If we subtract 425 from 450, we 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.

Going ahead to step 10:
The number 85 fits into 250 2 times, leaving a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 3046.2352
The remainder is 80 after subtracting 170 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 11:
When dividing 800 by 85, we get 9 with a remainder of 35.
The next digit of our result is 9. 
Result so far: 3046.23529
Subtracting 765 from 800 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.

Going ahead to step 12:
85 can be fit into 350 4 times, resulting in a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 3046.235294
If we subtract 340 from 350, we 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.

On to step 13:
85 goes into 100 1 times with a remainder of 15.
The next digit of our result is 1. 
Result so far: 3046.2352941
Subtracting 85 from 100 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 14:
When dividing 150 by 85, we get 1 with a remainder of 65.
Use 1 as the next digit of our solution. 
Result so far: 3046.23529411
Deduct 85 from 150 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final result is 3046.23529411 with a remainder of 6.5e-08.
