We look at the division of 63239494 by 810 
We want to divide 63239494 by 810.

On to step 1:
When dividing 6 by 810, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 810

Advancing to step 2:
63 divided by 810 is 0 with a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Append the next digit (2) from the dividend to 63 and continue with: 632 / 810

On to step 3:
632 divided by 810 is 0 with a remainder of 632.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 632 and we're left with 632.
Bring next digit (3) of the dividend behind the 632 and repeat the process: 6323 / 810

Step 4:
If we divide 6323 by 810, we get 7 and a remainder of 653.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 5670 from 6323, we get 653.
Bring next digit (9) of the dividend behind the 653 and repeat the process: 6539 / 810

On to step 5:
810 can be fit into 6539 8 times, resulting in a remainder of 59.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
If we take 6480 away from 6539, we end up with 59.
Include the next digit (4) from the dividend after 59, then repeat: 594 / 810

Going ahead to step 6:
594 divided by 810 is 0 with a remainder of 594.
Write down 0 as next digit of the result. 
Result so far: 780.0
If we subtract 0 from 594, we get 594.
Bring next digit (9) of the dividend behind the 594 and repeat the process: 5949 / 810

Let's proceed to step 7:
If we divide 5949 by 810, we get 7 and a remainder of 279.
The next digit of our result is 7. 
Result so far: 7807.0
Subtracting 5670 from 5949 leaves us with 279.
Take the next digit (4) from the dividend and append it to 279, then repeat: 2794 / 810

Going ahead to step 8:
2794 divided by 810 is 3 with a remainder of 364.
Write down 3 as next digit of the result. 
Result so far: 78073.0
If we subtract 2430 from 2794, we get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Going ahead to step 9:
810 can be fit into 3640 4 times, resulting in a remainder of 400.
The next digit of our result is 4. 
Result so far: 78073.4
Subtract 3240 from 3640 to 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.

Let's proceed to step 10:
810 goes into 4000 4 times with a remainder of 760.
Record the quotient 4 as the next digit in the result. 
Result so far: 78073.44
The remainder is 760 after subtracting 3240 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Our division results in 78073.44 with a remaining 0.76.
