800580 ÷ 65 
Let's see how many times 65 fits into 800580.

Going ahead to step 1:
When dividing 8 by 65, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 65

On to step 2:
65 can be fit into 80 1 times, resulting in a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 65 from 80, we get 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 65

On to step 3:
When dividing 150 by 65, we get 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 130 from 150, we get 20.
Include the next digit (5) from the dividend after 20, then repeat: 205 / 65

Step 4:
65 goes into 205 3 times with a remainder of 10.
The next digit of our result is 3. 
Result so far: 123.0
If we take 195 away from 205, we end up with 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 65

On to step 5:
The number 65 fits into 108 1 times, leaving a remainder of 43.
The next digit of our result is 1. 
Result so far: 1231.0
If we subtract 65 from 108, we get 43.
Bring next digit (0) of the dividend behind the 43 and repeat the process: 430 / 65

Let's proceed to step 6:
When dividing 430 by 65, we get 6 with a remainder of 40.
The next digit of our result is 6. 
Result so far: 12316.0
Deduct 390 from 430 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 7:
The number 65 fits into 400 6 times, leaving a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 12316.6
Deduct 390 from 400 and we're left with 10.
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 8:
When dividing 100 by 65, we get 1 with a remainder of 35.
Put 1 as the next digit of the answer. 
Result so far: 12316.61
Subtracting 65 from 100 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 9:
The number 65 fits into 350 5 times, leaving a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 12316.615
Subtract 325 from 350 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
When dividing 250 by 65, we get 3 with a remainder of 55.
Record the quotient 3 as the next digit in the result. 
Result so far: 12316.6153
Deduct 195 from 250 and we're left with 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 11:
550 divided by 65 is 8 with a remainder of 30.
The next digit of our result is 8. 
Result so far: 12316.61538
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.

Advancing to step 12:
If we divide 300 by 65, we get 4 and a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 12316.615384
Deduct 260 from 300 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 13:
When dividing 400 by 65, we get 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 12316.6153846
If we subtract 390 from 400, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 14:
65 goes into 100 1 times with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 12316.61538461
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.

The quotient of the division is 12316.61538461, and the remainder is 3.5e-08.
