We're dividing 288120 by 86 
We want to figure out the number of times 288120 can be divided 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
If we take 0 away from 2, we end up with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 86

Let's proceed to step 2:
86 goes into 28 0 times with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Include the next digit (8) from the dividend after 28, then repeat: 288 / 86

Going ahead to step 3:
288 divided by 86 is 3 with a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 258 from 288, we get 30.
Fetch the next digit (1) from the dividend, attach it to 30 and continue: 301 / 86

On to step 4:
When dividing 301 by 86, we get 3 with a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 33.0
The remainder is 43 after subtracting 258 from 301.
Fetch the next digit (2) from the dividend, attach it to 43 and continue: 432 / 86

Advancing to step 5:
432 divided by 86 is 5 with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 335.0
Subtracting 430 from 432 leaves us with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 86

Moving on to step 6:
If we divide 20 by 86, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 3350.0
Subtracting 0 from 20 leaves us with 20.
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 next digit of our result is 2. 
Result so far: 3350.2
Subtracting 172 from 200 leaves us 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.

Going ahead to step 8:
The number 86 fits into 280 3 times, leaving a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 3350.23
The remainder is 22 after subtracting 258 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
If we divide 220 by 86, we get 2 and a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 3350.232
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.

Going ahead to step 10:
86 goes into 480 5 times with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 3350.2325
Subtract 430 from 480 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 11:
86 goes into 500 5 times with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 3350.23255
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.

After the division, we end up with 3350.23255 and a remainder of 7e-05.
