Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 816

On to step 2:
34 divided by 816 is 0 with a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 34 to get 34.
Fetch the next digit (9) from the dividend, attach it to 34 and continue: 349 / 816

Advancing to step 3:
349 divided by 816 is 0 with a remainder of 349.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 349, we get 349.
Grab the next digit (7) from the dividend, add it to 349, then carry on: 3497 / 816

When dividing 3497 by 816, we get 4 with a remainder of 233.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 3264 from 3497 leaves us with 233.
Take the next digit (8) from the dividend and append it to 233, then repeat: 2338 / 816

Advancing to step 5:
If we divide 2338 by 816, we get 2 and a remainder of 706.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Subtracting 1632 from 2338 leaves us with 706.
Append the next digit (1) from the dividend to 706 and continue with: 7061 / 816

Let's proceed to step 6:
7061 divided by 816 is 8 with a remainder of 533.
Put 8 as the next digit of the answer. 
Result so far: 428.0
Subtracting 6528 from 7061 leaves us with 533.
Bring next digit (7) of the dividend behind the 533 and repeat the process: 5337 / 816

On to step 7:
816 can be fit into 5337 6 times, resulting in a remainder of 441.
Use 6 as the next digit of our solution. 
Result so far: 4286.0
Deduct 4896 from 5337 and we're left with 441.
Take the next digit (4) from the dividend and append it to 441, then repeat: 4414 / 816

Moving on to step 8:
The number 816 fits into 4414 5 times, leaving a remainder of 334.
Write down 5 as next digit of the result. 
Result so far: 42865.0
Subtract 4080 from 4414 to get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Going ahead to step 9:
The number 816 fits into 3340 4 times, leaving a remainder of 76.
The next digit of our result is 4. 
Result so far: 42865.4
Deduct 3264 from 3340 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 10:
If we divide 760 by 816, we get 0 and a remainder of 760.
The next digit of our result is 0. 
Result so far: 42865.4
Subtract 0 from 760 to get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Let's proceed to step 11:
The number 816 fits into 7600 9 times, leaving a remainder of 256.
The number 9 becomes the next digit in our result. 
Result so far: 42865.409
The remainder is 256 after subtracting 7344 from 7600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 12:
If we divide 2560 by 816, we get 3 and a remainder of 112.
Put 3 as the next digit of the answer. 
Result so far: 42865.4093
Subtracting 2448 from 2560 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 13:
816 goes into 1120 1 times with a remainder of 304.
Write down 1 as next digit of the result. 
Result so far: 42865.40931
If we subtract 816 from 1120, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Advancing to step 14:
816 can be fit into 3040 3 times, resulting in a remainder of 592.
Write down 3 as next digit of the result. 
Result so far: 42865.409313
The remainder is 592 after subtracting 2448 from 3040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Step 15:
The number 816 fits into 5920 7 times, leaving a remainder of 208.
Put 7 as the next digit of the answer. 
Result so far: 42865.4093137
Subtract 5712 from 5920 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 16:
The number 816 fits into 2080 2 times, leaving a remainder of 448.
Use 2 as the next digit of our solution. 
Result so far: 42865.40931372
If we subtract 1632 from 2080, we 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.

The final result is 42865.40931372 with a remainder of 4.48e-07.
