We look at the division of 815963 by 65 
Our goal is to divide 815963 by 65.

On to step 1:
65 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 65

Step 2:
The number 65 fits into 81 1 times, leaving a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 65 from 81 leaves us with 16.
Fetch the next digit (5) from the dividend, attach it to 16 and continue: 165 / 65

Let's proceed to step 3:
The number 65 fits into 165 2 times, leaving a remainder of 35.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 130 from 165 to get 35.
Include the next digit (9) from the dividend after 35, then repeat: 359 / 65

Moving on to step 4:
65 goes into 359 5 times with a remainder of 34.
The next digit of our result is 5. 
Result so far: 125.0
The remainder is 34 after subtracting 325 from 359.
Include the next digit (6) from the dividend after 34, then repeat: 346 / 65

Let's proceed to step 5:
If we divide 346 by 65, we get 5 and a remainder of 21.
Write down 5 as next digit of the result. 
Result so far: 1255.0
The remainder is 21 after subtracting 325 from 346.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 65

Let's proceed to step 6:
213 divided by 65 is 3 with a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 12553.0
Subtract 195 from 213 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 7:
65 can be fit into 180 2 times, resulting in a remainder of 50.
Put 2 as the next digit of the answer. 
Result so far: 12553.2
If we subtract 130 from 180, we 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.

Advancing to step 8:
The number 65 fits into 500 7 times, leaving a remainder of 45.
Put 7 as the next digit of the answer. 
Result so far: 12553.27
The remainder is 45 after subtracting 455 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 9:
450 divided by 65 is 6 with a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 12553.276
Subtract 390 from 450 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
When dividing 600 by 65, we get 9 with a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 12553.2769
The remainder is 15 after subtracting 585 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 11:
When dividing 150 by 65, we get 2 with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 12553.27692
Subtracting 130 from 150 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.

Advancing to step 12:
65 goes into 200 3 times with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 12553.276923
Subtract 195 from 200 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 13:
65 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 12553.276923
Deduct 0 from 50 and we're left 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.

Advancing to step 14:
The number 65 fits into 500 7 times, leaving a remainder of 45.
Write down 7 as next digit of the result. 
Result so far: 12553.27692307
If we subtract 455 from 500, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final result is 12553.27692307 with a remainder of 4.5e-08.
