We look at the division of 63840840 by 817 
Our goal is to divide 63840840 by 817.

Let's proceed to step 1:
817 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 817

Step 2:
When dividing 63 by 817, we get 0 with a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Bring next digit (8) of the dividend behind the 63 and repeat the process: 638 / 817

Let's proceed to step 3:
When dividing 638 by 817, we get 0 with a remainder of 638.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 638 and we're left with 638.
Bring next digit (4) of the dividend behind the 638 and repeat the process: 6384 / 817

Let's proceed to step 4:
If we divide 6384 by 817, we get 7 and a remainder of 665.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 5719 from 6384 and we're left with 665.
Include the next digit (0) from the dividend after 665, then repeat: 6650 / 817

Going ahead to step 5:
817 can be fit into 6650 8 times, resulting in a remainder of 114.
The next digit of our result is 8. 
Result so far: 78.0
Subtract 6536 from 6650 to get 114.
Fetch the next digit (8) from the dividend, attach it to 114 and continue: 1148 / 817

Advancing to step 6:
The number 817 fits into 1148 1 times, leaving a remainder of 331.
The next digit of our result is 1. 
Result so far: 781.0
Subtract 817 from 1148 to get 331.
Take the next digit (4) from the dividend and append it to 331, then repeat: 3314 / 817

Going ahead to step 7:
If we divide 3314 by 817, we get 4 and a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 7814.0
Subtract 3268 from 3314 to get 46.
Include the next digit (0) from the dividend after 46, then repeat: 460 / 817

Going ahead to step 8:
817 goes into 460 0 times with a remainder of 460.
Write down 0 as next digit of the result. 
Result so far: 78140.0
Subtracting 0 from 460 leaves us with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 9:
4600 divided by 817 is 5 with a remainder of 515.
The next digit of our result is 5. 
Result so far: 78140.5
The remainder is 515 after subtracting 4085 from 4600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Going ahead to step 10:
817 can be fit into 5150 6 times, resulting in a remainder of 248.
Use 6 as the next digit of our solution. 
Result so far: 78140.56
If we take 4902 away from 5150, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 11:
2480 divided by 817 is 3 with a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 78140.563
Deduct 2451 from 2480 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 12:
When dividing 290 by 817, we get 0 with a remainder of 290.
The number 0 becomes the next digit in our result. 
Result so far: 78140.563
Subtract 0 from 290 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

On to step 13:
The number 817 fits into 2900 3 times, leaving a remainder of 449.
The next digit of our result is 3. 
Result so far: 78140.56303
If we take 2451 away from 2900, we end up with 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Going ahead to step 14:
If we divide 4490 by 817, we get 5 and a remainder of 405.
Put 5 as the next digit of the answer. 
Result so far: 78140.563035
Deduct 4085 from 4490 and we're left with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

On to step 15:
If we divide 4050 by 817, we get 4 and a remainder of 782.
Record the quotient 4 as the next digit in the result. 
Result so far: 78140.5630354
Subtracting 3268 from 4050 leaves us with 782.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7820, and continue the process.

Going ahead to step 16:
817 can be fit into 7820 9 times, resulting in a remainder of 467.
Put 9 as the next digit of the answer. 
Result so far: 78140.56303549
If we subtract 7353 from 7820, we get 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

The final outcome is 78140.56303549, with a leftover of 4.67e-07.
