Fetch the next digit (5) from the dividend, attach it to 636 and continue: 6365 / 816

Step 4:
816 can be fit into 6365 7 times, resulting in a remainder of 653.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 5712 from 6365 to get 653.
Fetch the next digit (0) from the dividend, attach it to 653 and continue: 6530 / 816

Advancing to step 5:
The number 816 fits into 6530 8 times, leaving a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Deduct 6528 from 6530 and we're left with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 816

Going ahead to step 6:
816 can be fit into 27 0 times, resulting in a remainder of 27.
Put 0 as the next digit of the answer. 
Result so far: 780.0
If we subtract 0 from 27, we get 27.
Take the next digit (2) from the dividend and append it to 27, then repeat: 272 / 816

On to step 7:
816 goes into 272 0 times with a remainder of 272.
Put 0 as the next digit of the answer. 
Result so far: 7800.0
Deduct 0 from 272 and we're left with 272.
Bring next digit (6) of the dividend behind the 272 and repeat the process: 2726 / 816

Advancing to step 8:
816 goes into 2726 3 times with a remainder of 278.
Use 3 as the next digit of our solution. 
Result so far: 78003.0
Deduct 2448 from 2726 and we're left with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Going ahead to step 9:
When dividing 2780 by 816, we get 3 with a remainder of 332.
Record the quotient 3 as the next digit in the result. 
Result so far: 78003.3
Deduct 2448 from 2780 and we're left with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Moving on to step 10:
3320 divided by 816 is 4 with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 78003.34
The remainder is 56 after subtracting 3264 from 3320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 11:
560 divided by 816 is 0 with a remainder of 560.
Write down 0 as next digit of the result. 
Result so far: 78003.34
Deduct 0 from 560 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 12:
When dividing 5600 by 816, we get 6 with a remainder of 704.
The next digit of our result is 6. 
Result so far: 78003.3406
The remainder is 704 after subtracting 4896 from 5600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Let's proceed to step 13:
When dividing 7040 by 816, we get 8 with a remainder of 512.
Write down 8 as next digit of the result. 
Result so far: 78003.34068
If we subtract 6528 from 7040, we get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Moving on to step 14:
The number 816 fits into 5120 6 times, leaving a remainder of 224.
Put 6 as the next digit of the answer. 
Result so far: 78003.340686
Subtract 4896 from 5120 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 15:
When dividing 2240 by 816, we get 2 with a remainder of 608.
Write down 2 as next digit of the result. 
Result so far: 78003.3406862
Subtracting 1632 from 2240 leaves us with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Advancing to step 16:
816 can be fit into 6080 7 times, resulting in a remainder of 368.
Use 7 as the next digit of our solution. 
Result so far: 78003.34068627
Deduct 5712 from 6080 and we're left with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

The final result is 78003.34068627 with a remainder of 3.68e-07.
