We look at the division of 65262458 by 839 
We want to figure out the number of times 65262458 can be divided by 839.

On to step 1:
The number 839 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 839

Going ahead to step 2:
If we divide 65 by 839, we get 0 and a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 65 leaves us with 65.
Fetch the next digit (2) from the dividend, attach it to 65 and continue: 652 / 839

Going ahead to step 3:
652 divided by 839 is 0 with a remainder of 652.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 652, we get 652.
Take the next digit (6) from the dividend and append it to 652, then repeat: 6526 / 839

Step 4:
839 goes into 6526 7 times with a remainder of 653.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 653 after subtracting 5873 from 6526.
Grab the next digit (2) from the dividend, add it to 653, then carry on: 6532 / 839

Advancing to step 5:
When dividing 6532 by 839, we get 7 with a remainder of 659.
Put 7 as the next digit of the answer. 
Result so far: 77.0
If we take 5873 away from 6532, we end up with 659.
Include the next digit (4) from the dividend after 659, then repeat: 6594 / 839

Step 6:
The number 839 fits into 6594 7 times, leaving a remainder of 721.
The next digit of our result is 7. 
Result so far: 777.0
If we subtract 5873 from 6594, we get 721.
Grab the next digit (5) from the dividend, add it to 721, then carry on: 7215 / 839

Moving on to step 7:
839 can be fit into 7215 8 times, resulting in a remainder of 503.
The number 8 becomes the next digit in our result. 
Result so far: 7778.0
If we subtract 6712 from 7215, we get 503.
Fetch the next digit (8) from the dividend, attach it to 503 and continue: 5038 / 839

Step 8:
When dividing 5038 by 839, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 77786.0
Subtracting 5034 from 5038 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
839 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 77786.0
If we take 0 away from 40, we end up 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.

Moving on to step 10:
The number 839 fits into 400 0 times, leaving a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 77786.0
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The quotient of the division is 77786.0, and the remainder is 0.4.
