We divide 287520 by 65
We want to figure out the number of times 287520 can be divided by 65.

Step 1:
2 divided by 65 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 65

Going ahead to step 2:
The number 65 fits into 28 0 times, leaving a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Fetch the next digit (7) from the dividend, attach it to 28 and continue: 287 / 65

Step 3:
When dividing 287 by 65, we get 4 with a remainder of 27.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 260 away from 287, we end up with 27.
Append the next digit (5) from the dividend to 27 and continue with: 275 / 65

Advancing to step 4:
The number 65 fits into 275 4 times, leaving a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 44.0
Deduct 260 from 275 and we're left with 15.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 65

Advancing to step 5:
The number 65 fits into 152 2 times, leaving a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 442.0
Subtract 130 from 152 to get 22.
Take the next digit (0) from the dividend and append it to 22, then repeat: 220 / 65

Going ahead to step 6:
65 goes into 220 3 times with a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 4423.0
If we take 195 away from 220, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 7:
65 can be fit into 250 3 times, resulting in a remainder of 55.
The number 3 becomes the next digit in our result. 
Result so far: 4423.3
If we subtract 195 from 250, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 8:
The number 65 fits into 550 8 times, leaving a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 4423.38
Subtract 520 from 550 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
The number 65 fits into 300 4 times, leaving a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 4423.384
The remainder is 40 after subtracting 260 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
The number 65 fits into 400 6 times, leaving a remainder of 10.
The next digit of our result is 6. 
Result so far: 4423.3846
The remainder is 10 after subtracting 390 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
When dividing 100 by 65, we get 1 with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 4423.38461
Subtract 65 from 100 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 12:
350 divided by 65 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 4423.384615
The remainder is 25 after subtracting 325 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 13:
If we divide 250 by 65, we get 3 and a remainder of 55.
Use 3 as the next digit of our solution. 
Result so far: 4423.3846153
Subtract 195 from 250 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 14:
65 goes into 550 8 times with a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 4423.38461538
If we take 520 away from 550, we end up 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.

The final outcome is 4423.38461538, with a leftover of 3e-08.
