258271 divided by 86 
Our goal is to divide 258271 by 86.

Moving on to step 1:
86 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 86

On to step 2:
86 can be fit into 25 0 times, resulting in a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Take the next digit (8) from the dividend and append it to 25, then repeat: 258 / 86

Let's proceed to step 3:
If we divide 258 by 86, we get 3 and a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 258 from 258 to get 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 86

Step 4:
The number 86 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 30.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 86

Going ahead to step 5:
The number 86 fits into 27 0 times, leaving a remainder of 27.
The next digit of our result is 0. 
Result so far: 300.0
Subtract 0 from 27 to get 27.
Append the next digit (1) from the dividend to 27 and continue with: 271 / 86

Advancing to step 6:
When dividing 271 by 86, we get 3 with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 3003.0
If we subtract 258 from 271, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
If we divide 130 by 86, we get 1 and a remainder of 44.
Put 1 as the next digit of the answer. 
Result so far: 3003.1
Deduct 86 from 130 and we're left 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.

Let's proceed to step 8:
440 divided by 86 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 3003.15
If we subtract 430 from 440, 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.

Advancing to step 9:
When dividing 100 by 86, we get 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 3003.151
If we take 86 away from 100, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 10:
86 can be fit into 140 1 times, resulting in a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 3003.1511
Subtract 86 from 140 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The quotient of the division is 3003.1511, and the remainder is 0.00054.
