521240 divided by 65 
We want to figure out the number of times 521240 can be divided by 65.

Step 1:
65 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 65

Advancing to step 2:
When dividing 52 by 65, we get 0 with a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Include the next digit (1) from the dividend after 52, then repeat: 521 / 65

Let's proceed to step 3:
The number 65 fits into 521 8 times, leaving a remainder of 1.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 520 from 521 and we're left with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 65

Going ahead to step 4:
When dividing 12 by 65, we get 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
The remainder is 12 after subtracting 0 from 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 65

Going ahead to step 5:
When dividing 124 by 65, we get 1 with a remainder of 59.
The next digit of our result is 1. 
Result so far: 801.0
Deduct 65 from 124 and we're left with 59.
Include the next digit (0) from the dividend after 59, then repeat: 590 / 65

Advancing to step 6:
65 can be fit into 590 9 times, resulting in a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 8019.0
The remainder is 5 after subtracting 585 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
If we divide 50 by 65, we get 0 and a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 8019.0
Subtracting 0 from 50 leaves us 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 8:
500 divided by 65 is 7 with a remainder of 45.
The number 7 becomes the next digit in our result. 
Result so far: 8019.07
Subtract 455 from 500 to 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.

Going ahead to step 9:
If we divide 450 by 65, we get 6 and a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 8019.076
The remainder is 60 after subtracting 390 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
600 divided by 65 is 9 with a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 8019.0769
Subtracting 585 from 600 leaves us with 15.
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:
If we divide 150 by 65, we get 2 and a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 8019.07692
If we subtract 130 from 150, we get 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:
If we divide 200 by 65, we get 3 and a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 8019.076923
The remainder is 5 after subtracting 195 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 13:
50 divided by 65 is 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 8019.076923
Subtract 0 from 50 to 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 14:
65 can be fit into 500 7 times, resulting in a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 8019.07692307
If we take 455 away from 500, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

In conclusion, the division gives 8019.07692307 with a balance of 4.5e-08.
