256390 ÷ 86 
We want to divide 256390 by 86.

Moving on to step 1:
86 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 86

On to step 2:
The number 86 fits into 25 0 times, leaving a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Fetch the next digit (6) from the dividend, attach it to 25 and continue: 256 / 86

Going ahead to step 3:
If we divide 256 by 86, we get 2 and a remainder of 84.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 172 from 256 leaves us with 84.
Include the next digit (3) from the dividend after 84, then repeat: 843 / 86

Let's proceed to step 4:
The number 86 fits into 843 9 times, leaving a remainder of 69.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Subtract 774 from 843 to get 69.
Fetch the next digit (9) from the dividend, attach it to 69 and continue: 699 / 86

Going ahead to step 5:
699 divided by 86 is 8 with a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 298.0
If we subtract 688 from 699, we get 11.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 86

Step 6:
86 goes into 110 1 times with a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 2981.0
If we take 86 away from 110, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 7:
If we divide 240 by 86, we get 2 and a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 2981.2
Subtracting 172 from 240 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 8:
When dividing 680 by 86, we get 7 with a remainder of 78.
Write down 7 as next digit of the result. 
Result so far: 2981.27
If we subtract 602 from 680, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 9:
The number 86 fits into 780 9 times, leaving a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 2981.279
If we subtract 774 from 780, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
If we divide 60 by 86, we get 0 and a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 2981.279
Subtracting 0 from 60 leaves us with 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 11:
If we divide 600 by 86, we get 6 and a remainder of 84.
Write down 6 as next digit of the result. 
Result so far: 2981.27906
Subtract 516 from 600 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 12:
840 divided by 86 is 9 with a remainder of 66.
Record the quotient 9 as the next digit in the result. 
Result so far: 2981.279069
If we subtract 774 from 840, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 13:
If we divide 660 by 86, we get 7 and a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 2981.2790697
Subtracting 602 from 660 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 14:
580 divided by 86 is 6 with a remainder of 64.
The next digit of our result is 6. 
Result so far: 2981.27906976
If we take 516 away from 580, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 2981.27906976 with a remaining 6.4e-08.
