289238 divided by 86 
Let's see how many times 86 fits into 289238.

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
If we take 0 away from 2, we end up with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 86

Step 2:
86 goes into 28 0 times with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Fetch the next digit (9) from the dividend, attach it to 28 and continue: 289 / 86

Going ahead to step 3:
86 goes into 289 3 times with a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 258 away from 289, we end up with 31.
Grab the next digit (2) from the dividend, add it to 31, then carry on: 312 / 86

Going ahead to step 4:
86 goes into 312 3 times with a remainder of 54.
Write down 3 as next digit of the result. 
Result so far: 33.0
Subtracting 258 from 312 leaves us with 54.
Bring next digit (3) of the dividend behind the 54 and repeat the process: 543 / 86

Moving on to step 5:
543 divided by 86 is 6 with a remainder of 27.
Put 6 as the next digit of the answer. 
Result so far: 336.0
The remainder is 27 after subtracting 516 from 543.
Fetch the next digit (8) from the dividend, attach it to 27 and continue: 278 / 86

Advancing to step 6:
When dividing 278 by 86, we get 3 with a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 3363.0
The remainder is 20 after subtracting 258 from 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
If we divide 200 by 86, we get 2 and a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 3363.2
Deduct 172 from 200 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 8:
When dividing 280 by 86, we get 3 with a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 3363.23
Subtract 258 from 280 to 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.

Let's proceed to step 9:
If we divide 220 by 86, we get 2 and a remainder of 48.
The next digit of our result is 2. 
Result so far: 3363.232
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.

Moving on to step 10:
86 can be fit into 480 5 times, resulting in a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 3363.2325
If we take 430 away from 480, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 11:
86 goes into 500 5 times with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 3363.23255
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.

Our division results in 3363.23255 with a remaining 7e-05.
