Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Take the next digit (3) from the dividend and append it to 81, then repeat: 813 / 394

Going ahead to step 3:
813 divided by 394 is 2 with a remainder of 25.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 788 from 813 leaves us with 25.
Fetch the next digit (2) from the dividend, attach it to 25 and continue: 252 / 394

Advancing to step 4:
The number 394 fits into 252 0 times, leaving a remainder of 252.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Deduct 0 from 252 and we're left with 252.
Grab the next digit (2) from the dividend, add it to 252, then carry on: 2522 / 394

Step 5:
When dividing 2522 by 394, we get 6 with a remainder of 158.
Put 6 as the next digit of the answer. 
Result so far: 206.0
Subtracting 2364 from 2522 leaves us with 158.
Grab the next digit (5) from the dividend, add it to 158, then carry on: 1585 / 394

Advancing to step 6:
394 goes into 1585 4 times with a remainder of 9.
The next digit of our result is 4. 
Result so far: 2064.0
Deduct 1576 from 1585 and we're left with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 394

Going ahead to step 7:
The number 394 fits into 91 0 times, leaving a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 20640.0
Subtracting 0 from 91 leaves us with 91.
Fetch the next digit (6) from the dividend, attach it to 91 and continue: 916 / 394

On to step 8:
If we divide 916 by 394, we get 2 and a remainder of 128.
Write down 2 as next digit of the result. 
Result so far: 206402.0
Subtracting 788 from 916 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 9:
394 can be fit into 1280 3 times, resulting in a remainder of 98.
Record the quotient 3 as the next digit in the result. 
Result so far: 206402.3
The remainder is 98 after subtracting 1182 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 10:
394 can be fit into 980 2 times, resulting in a remainder of 192.
Write down 2 as next digit of the result. 
Result so far: 206402.32
Subtract 788 from 980 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 11:
If we divide 1920 by 394, we get 4 and a remainder of 344.
Record the quotient 4 as the next digit in the result. 
Result so far: 206402.324
Deduct 1576 from 1920 and we're left with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Advancing to step 12:
The number 394 fits into 3440 8 times, leaving a remainder of 288.
The number 8 becomes the next digit in our result. 
Result so far: 206402.3248
The remainder is 288 after subtracting 3152 from 3440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Going ahead to step 13:
The number 394 fits into 2880 7 times, leaving a remainder of 122.
Put 7 as the next digit of the answer. 
Result so far: 206402.32487
Deduct 2758 from 2880 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 14:
394 can be fit into 1220 3 times, resulting in a remainder of 38.
The next digit of our result is 3. 
Result so far: 206402.324873
If we subtract 1182 from 1220, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 15:
If we divide 380 by 394, we get 0 and a remainder of 380.
The next digit of our result is 0. 
Result so far: 206402.324873
Subtracting 0 from 380 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 16:
394 can be fit into 3800 9 times, resulting in a remainder of 254.
Put 9 as the next digit of the answer. 
Result so far: 206402.32487309
If we take 3546 away from 3800, we end up with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

The final outcome is 206402.32487309, with a leftover of 2.54e-07.
