Let's divide 63999456 by 782
We want to figure out the number of times 63999456 can be divided by 782.

Step 1:
The number 782 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 782

On to step 2:
782 can be fit into 63 0 times, resulting in a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Include the next digit (9) from the dividend after 63, then repeat: 639 / 782

Let's proceed to step 3:
If we divide 639 by 782, we get 0 and a remainder of 639.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 639 to get 639.
Fetch the next digit (9) from the dividend, attach it to 639 and continue: 6399 / 782

Let's proceed to step 4:
The number 782 fits into 6399 8 times, leaving a remainder of 143.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 6256 from 6399 leaves us with 143.
Take the next digit (9) from the dividend and append it to 143, then repeat: 1439 / 782

On to step 5:
782 can be fit into 1439 1 times, resulting in a remainder of 657.
Put 1 as the next digit of the answer. 
Result so far: 81.0
Subtract 782 from 1439 to get 657.
Append the next digit (4) from the dividend to 657 and continue with: 6574 / 782

Moving on to step 6:
6574 divided by 782 is 8 with a remainder of 318.
The next digit of our result is 8. 
Result so far: 818.0
If we take 6256 away from 6574, we end up with 318.
Fetch the next digit (5) from the dividend, attach it to 318 and continue: 3185 / 782

Going ahead to step 7:
782 can be fit into 3185 4 times, resulting in a remainder of 57.
The next digit of our result is 4. 
Result so far: 8184.0
Subtract 3128 from 3185 to get 57.
Bring next digit (6) of the dividend behind the 57 and repeat the process: 576 / 782

Advancing to step 8:
The number 782 fits into 576 0 times, leaving a remainder of 576.
The next digit of our result is 0. 
Result so far: 81840.0
If we subtract 0 from 576, we get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Let's proceed to step 9:
If we divide 5760 by 782, we get 7 and a remainder of 286.
Record the quotient 7 as the next digit in the result. 
Result so far: 81840.7
Subtract 5474 from 5760 to get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

On to step 10:
If we divide 2860 by 782, we get 3 and a remainder of 514.
Use 3 as the next digit of our solution. 
Result so far: 81840.73
If we subtract 2346 from 2860, we get 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Going ahead to step 11:
782 can be fit into 5140 6 times, resulting in a remainder of 448.
Record the quotient 6 as the next digit in the result. 
Result so far: 81840.736
Subtract 4692 from 5140 to get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Step 12:
782 can be fit into 4480 5 times, resulting in a remainder of 570.
Record the quotient 5 as the next digit in the result. 
Result so far: 81840.7365
Deduct 3910 from 4480 and we're left with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Step 13:
5700 divided by 782 is 7 with a remainder of 226.
The number 7 becomes the next digit in our result. 
Result so far: 81840.73657
If we take 5474 away from 5700, we end up with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Advancing to step 14:
782 can be fit into 2260 2 times, resulting in a remainder of 696.
Use 2 as the next digit of our solution. 
Result so far: 81840.736572
Deduct 1564 from 2260 and we're left with 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Advancing to step 15:
When dividing 6960 by 782, we get 8 with a remainder of 704.
Put 8 as the next digit of the answer. 
Result so far: 81840.7365728
If we take 6256 away from 6960, we end up with 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

On to step 16:
7040 divided by 782 is 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 81840.73657289
Subtracting 7038 from 7040 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 81840.73657289 with a balance of 2e-09.
