We're dividing 286874 by 86 
We want to divide 286874 by 86.

Advancing to step 1:
If we divide 2 by 86, we get 0 and 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.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 86

Let's proceed to step 2:
When dividing 28 by 86, we get 0 with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Include the next digit (6) from the dividend after 28, then repeat: 286 / 86

Going ahead to step 3:
86 goes into 286 3 times with a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 258 from 286 to get 28.
Append the next digit (8) from the dividend to 28 and continue with: 288 / 86

Going ahead to step 4:
The number 86 fits into 288 3 times, leaving a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
If we take 258 away from 288, we end up with 30.
Grab the next digit (7) from the dividend, add it to 30, then carry on: 307 / 86

Advancing to step 5:
If we divide 307 by 86, we get 3 and a remainder of 49.
Record the quotient 3 as the next digit in the result. 
Result so far: 333.0
If we take 258 away from 307, we end up with 49.
Append the next digit (4) from the dividend to 49 and continue with: 494 / 86

Moving on to step 6:
When dividing 494 by 86, we get 5 with a remainder of 64.
Use 5 as the next digit of our solution. 
Result so far: 3335.0
Subtract 430 from 494 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 7:
When dividing 640 by 86, we get 7 with a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 3335.7
Deduct 602 from 640 and we're left 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.

Let's proceed to step 8:
380 divided by 86 is 4 with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 3335.74
Subtract 344 from 380 to 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 9:
86 goes into 360 4 times with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 3335.744
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 3335.744, and the remainder is 0.0016.
