259313 divided by 86 
We want to figure out the number of times 259313 can be divided by 86.

Step 1:
86 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 86

Moving on to step 2:
86 can be fit into 25 0 times, resulting in a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Fetch the next digit (9) from the dividend, attach it to 25 and continue: 259 / 86

Step 3:
When dividing 259 by 86, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 258 from 259 to get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 86

Step 4:
When dividing 13 by 86, we get 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
The remainder is 13 after subtracting 0 from 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 86

Let's proceed to step 5:
131 divided by 86 is 1 with a remainder of 45.
Record the quotient 1 as the next digit in the result. 
Result so far: 301.0
If we subtract 86 from 131, we get 45.
Fetch the next digit (3) from the dividend, attach it to 45 and continue: 453 / 86

Moving on to step 6:
If we divide 453 by 86, we get 5 and a remainder of 23.
Record the quotient 5 as the next digit in the result. 
Result so far: 3015.0
If we take 430 away from 453, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 7:
If we divide 230 by 86, we get 2 and a remainder of 58.
Write down 2 as next digit of the result. 
Result so far: 3015.2
The remainder is 58 after subtracting 172 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 8:
86 goes into 580 6 times with a remainder of 64.
The next digit of our result is 6. 
Result so far: 3015.26
Deduct 516 from 580 and we're left 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.

Going ahead to step 9:
86 goes into 640 7 times with a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 3015.267
If we take 602 away from 640, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 10:
380 divided by 86 is 4 with a remainder of 36.
The next digit of our result is 4. 
Result so far: 3015.2674
If we subtract 344 from 380, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 11:
If we divide 360 by 86, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 3015.26744
Subtract 344 from 360 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 3015.26744, and the remainder is 1.6e-05.
