250581 ÷ 86 
We want to figure out the number of times 250581 can be divided by 86.

Advancing to step 1:
2 divided by 86 is 0 with 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.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 86

On to step 2:
25 divided by 86 is 0 with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Bring next digit (0) of the dividend behind the 25 and repeat the process: 250 / 86

Step 3:
The number 86 fits into 250 2 times, leaving a remainder of 78.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 172 from 250 and we're left with 78.
Include the next digit (5) from the dividend after 78, then repeat: 785 / 86

On to step 4:
If we divide 785 by 86, we get 9 and a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 29.0
If we subtract 774 from 785, we get 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 86

Moving on to step 5:
86 can be fit into 118 1 times, resulting in a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 291.0
Subtracting 86 from 118 leaves us with 32.
Bring next digit (1) of the dividend behind the 32 and repeat the process: 321 / 86

Going ahead to step 6:
If we divide 321 by 86, we get 3 and a remainder of 63.
Record the quotient 3 as the next digit in the result. 
Result so far: 2913.0
The remainder is 63 after subtracting 258 from 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 7:
When dividing 630 by 86, we get 7 with a remainder of 28.
Record the quotient 7 as the next digit in the result. 
Result so far: 2913.7
Subtract 602 from 630 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 8:
When dividing 280 by 86, we get 3 with a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 2913.73
If we subtract 258 from 280, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 9:
86 goes into 220 2 times with a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 2913.732
Subtract 172 from 220 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 10:
If we divide 480 by 86, we get 5 and a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 2913.7325
The remainder is 50 after subtracting 430 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 11:
When dividing 500 by 86, we get 5 with a remainder of 70.
The next digit of our result is 5. 
Result so far: 2913.73255
If we subtract 430 from 500, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The quotient of the division is 2913.73255, and the remainder is 7e-05.
