288513 divided by 39 
We want to figure out the number of times 288513 can be divided by 39.

Step 1:
39 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 39

Moving on to step 2:
39 can be fit into 28 0 times, resulting in a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Include the next digit (8) from the dividend after 28, then repeat: 288 / 39

Going ahead to step 3:
288 divided by 39 is 7 with a remainder of 15.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 273 from 288 and we're left with 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 39

Step 4:
If we divide 155 by 39, we get 3 and a remainder of 38.
The next digit of our result is 3. 
Result so far: 73.0
Subtracting 117 from 155 leaves us with 38.
Grab the next digit (1) from the dividend, add it to 38, then carry on: 381 / 39

Step 5:
381 divided by 39 is 9 with a remainder of 30.
Write down 9 as next digit of the result. 
Result so far: 739.0
If we take 351 away from 381, we end up with 30.
Grab the next digit (3) from the dividend, add it to 30, then carry on: 303 / 39

Let's proceed to step 6:
39 can be fit into 303 7 times, resulting in a remainder of 30.
Write down 7 as next digit of the result. 
Result so far: 7397.0
The remainder is 30 after subtracting 273 from 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 7:
If we divide 300 by 39, we get 7 and a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 7397.7
If we take 273 away from 300, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 8:
The number 39 fits into 270 6 times, leaving a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 7397.76
Subtract 234 from 270 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.

Advancing to step 9:
If we divide 360 by 39, we get 9 and a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 7397.769
The remainder is 9 after subtracting 351 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 10:
39 can be fit into 90 2 times, resulting in a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 7397.7692
The remainder is 12 after subtracting 78 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
If we divide 120 by 39, we get 3 and a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 7397.76923
If we subtract 117 from 120, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 12:
30 divided by 39 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 7397.76923
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 13:
When dividing 300 by 39, we get 7 with a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 7397.7692307
Subtracting 273 from 300 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 14:
The number 39 fits into 270 6 times, leaving a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 7397.76923076
If we take 234 away from 270, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 7397.76923076, with a leftover of 3.6e-08.
