We look at the division of 53102458 by 65 
We want to figure out the number of times 53102458 can be divided by 65.

Moving on to step 1:
When dividing 5 by 65, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 65

On to step 2:
65 can be fit into 53 0 times, resulting in a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Grab the next digit (1) from the dividend, add it to 53, then carry on: 531 / 65

Let's proceed to step 3:
65 can be fit into 531 8 times, resulting in a remainder of 11.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 520 from 531 and we're left with 11.
Grab the next digit (0) from the dividend, add it to 11, then carry on: 110 / 65

Step 4:
If we divide 110 by 65, we get 1 and a remainder of 45.
The next digit of our result is 1. 
Result so far: 81.0
Subtracting 65 from 110 leaves us with 45.
Fetch the next digit (2) from the dividend, attach it to 45 and continue: 452 / 65

Step 5:
65 goes into 452 6 times with a remainder of 62.
Put 6 as the next digit of the answer. 
Result so far: 816.0
If we take 390 away from 452, we end up with 62.
Take the next digit (4) from the dividend and append it to 62, then repeat: 624 / 65

Advancing to step 6:
When dividing 624 by 65, we get 9 with a remainder of 39.
Record the quotient 9 as the next digit in the result. 
Result so far: 8169.0
If we take 585 away from 624, we end up with 39.
Fetch the next digit (5) from the dividend, attach it to 39 and continue: 395 / 65

Going ahead to step 7:
If we divide 395 by 65, we get 6 and a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 81696.0
If we take 390 away from 395, we end up with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 65

Advancing to step 8:
65 goes into 58 0 times with a remainder of 58.
The next digit of our result is 0. 
Result so far: 816960.0
If we subtract 0 from 58, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 9:
580 divided by 65 is 8 with a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 816960.8
The remainder is 60 after subtracting 520 from 580.
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:
600 divided by 65 is 9 with a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 816960.89
If we take 585 away from 600, we end up 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.

Step 11:
The number 65 fits into 150 2 times, leaving a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 816960.892
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.

Moving on to step 12:
When dividing 200 by 65, we get 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 816960.8923
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.

Advancing to step 13:
65 goes into 50 0 times with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 816960.8923
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 14:
If we divide 500 by 65, we get 7 and a remainder of 45.
Write down 7 as next digit of the result. 
Result so far: 816960.892307
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.

Advancing to step 15:
When dividing 450 by 65, we get 6 with a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 816960.8923076
Deduct 390 from 450 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 16:
65 can be fit into 600 9 times, resulting in a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 816960.89230769
Subtract 585 from 600 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 816960.89230769 and a remainder of 1.5e-08.
