640020 ÷ 65 
We're looking to find how many times 65 goes into 640020.

Let's proceed to step 1:
65 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 65

Moving on to step 2:
If we divide 64 by 65, we get 0 and a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Grab the next digit (0) from the dividend, add it to 64, then carry on: 640 / 65

Let's proceed to step 3:
When dividing 640 by 65, we get 9 with a remainder of 55.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 585 from 640 leaves us with 55.
Include the next digit (0) from the dividend after 55, then repeat: 550 / 65

Let's proceed to step 4:
65 can be fit into 550 8 times, resulting in a remainder of 30.
Put 8 as the next digit of the answer. 
Result so far: 98.0
If we subtract 520 from 550, we get 30.
Bring next digit (2) of the dividend behind the 30 and repeat the process: 302 / 65

Advancing to step 5:
When dividing 302 by 65, we get 4 with a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 984.0
Subtracting 260 from 302 leaves us with 42.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 65

Advancing to step 6:
If we divide 420 by 65, we get 6 and a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 9846.0
Deduct 390 from 420 and we're left 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 7:
65 can be fit into 300 4 times, resulting in a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 9846.4
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.

Advancing to step 8:
400 divided by 65 is 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 9846.46
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 9:
The number 65 fits into 100 1 times, leaving a remainder of 35.
The next digit of our result is 1. 
Result so far: 9846.461
The remainder is 35 after subtracting 65 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 10:
65 goes into 350 5 times with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 9846.4615
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.

Step 11:
When dividing 250 by 65, we get 3 with a remainder of 55.
Use 3 as the next digit of our solution. 
Result so far: 9846.46153
Subtracting 195 from 250 leaves us 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.

Going ahead to step 12:
550 divided by 65 is 8 with a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 9846.461538
If we subtract 520 from 550, we 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.

Going ahead to step 13:
65 goes into 300 4 times with a remainder of 40.
The next digit of our result is 4. 
Result so far: 9846.4615384
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.

Going ahead to step 14:
65 goes into 400 6 times with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 9846.46153846
If we take 390 away from 400, we end up 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.

The final outcome is 9846.46153846, with a leftover of 1e-08.
