Going ahead to step 5:
If we divide 862 by 816, we get 1 and a remainder of 46.
The number 1 becomes the next digit in our result. 
Result so far: 111.0
Deduct 816 from 862 and we're left with 46.
Fetch the next digit (5) from the dividend, attach it to 46 and continue: 465 / 816

Step 6:
The number 816 fits into 465 0 times, leaving a remainder of 465.
Write down 0 as next digit of the result. 
Result so far: 1110.0
The remainder is 465 after subtracting 0 from 465.
Include the next digit (8) from the dividend after 465, then repeat: 4658 / 816

Going ahead to step 7:
The number 816 fits into 4658 5 times, leaving a remainder of 578.
The number 5 becomes the next digit in our result. 
Result so far: 11105.0
Subtracting 4080 from 4658 leaves us with 578.
Include the next digit (6) from the dividend after 578, then repeat: 5786 / 816

Going ahead to step 8:
816 goes into 5786 7 times with a remainder of 74.
The next digit of our result is 7. 
Result so far: 111057.0
Deduct 5712 from 5786 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 9:
The number 816 fits into 740 0 times, leaving a remainder of 740.
Record the quotient 0 as the next digit in the result. 
Result so far: 111057.0
Deduct 0 from 740 and we're left with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Advancing to step 10:
816 goes into 7400 9 times with a remainder of 56.
Put 9 as the next digit of the answer. 
Result so far: 111057.09
Subtract 7344 from 7400 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 11:
If we divide 560 by 816, we get 0 and a remainder of 560.
Put 0 as the next digit of the answer. 
Result so far: 111057.09
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.

Advancing to step 12:
The number 816 fits into 5600 6 times, leaving a remainder of 704.
Use 6 as the next digit of our solution. 
Result so far: 111057.0906
Deduct 4896 from 5600 and we're left 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 13:
7040 divided by 816 is 8 with a remainder of 512.
The number 8 becomes the next digit in our result. 
Result so far: 111057.09068
Subtracting 6528 from 7040 leaves us with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

On to step 14:
816 can be fit into 5120 6 times, resulting in a remainder of 224.
The number 6 becomes the next digit in our result. 
Result so far: 111057.090686
The remainder is 224 after subtracting 4896 from 5120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Moving on to step 15:
816 goes into 2240 2 times with a remainder of 608.
Record the quotient 2 as the next digit in the result. 
Result so far: 111057.0906862
If we subtract 1632 from 2240, we get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Let's proceed 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: 111057.09068627
If we take 5712 away from 6080, we end up 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.

In conclusion, the division gives 111057.09068627 with a balance of 3.68e-07.
