When dividing 3 by 209, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 209

On to step 2:
209 goes into 31 0 times with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Append the next digit (0) from the dividend to 31 and continue with: 310 / 209

Going ahead to step 3:
209 can be fit into 310 1 times, resulting in a remainder of 101.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 209 from 310 to get 101.
Take the next digit (5) from the dividend and append it to 101, then repeat: 1015 / 209

Moving on to step 4:
If we divide 1015 by 209, we get 4 and a remainder of 179.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtracting 836 from 1015 leaves us with 179.
Grab the next digit (1) from the dividend, add it to 179, then carry on: 1791 / 209

Moving on to step 5:
The number 209 fits into 1791 8 times, leaving a remainder of 119.
Record the quotient 8 as the next digit in the result. 
Result so far: 148.0
If we subtract 1672 from 1791, we get 119.
Take the next digit (3) from the dividend and append it to 119, then repeat: 1193 / 209

Going ahead to step 6:
209 can be fit into 1193 5 times, resulting in a remainder of 148.
Record the quotient 5 as the next digit in the result. 
Result so far: 1485.0
The remainder is 148 after subtracting 1045 from 1193.
Grab the next digit (8) from the dividend, add it to 148, then carry on: 1488 / 209

Advancing to step 7:
The number 209 fits into 1488 7 times, leaving a remainder of 25.
The next digit of our result is 7. 
Result so far: 14857.0
Subtracting 1463 from 1488 leaves us with 25.
Grab the next digit (9) from the dividend, add it to 25, then carry on: 259 / 209

On to step 8:
When dividing 259 by 209, we get 1 with a remainder of 50.
Use 1 as the next digit of our solution. 
Result so far: 148571.0
Subtracting 209 from 259 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
500 divided by 209 is 2 with a remainder of 82.
The next digit of our result is 2. 
Result so far: 148571.2
Subtracting 418 from 500 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 10:
209 goes into 820 3 times with a remainder of 193.
The next digit of our result is 3. 
Result so far: 148571.23
Subtracting 627 from 820 leaves us with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Moving on to step 11:
209 goes into 1930 9 times with a remainder of 49.
Put 9 as the next digit of the answer. 
Result so far: 148571.239
The remainder is 49 after subtracting 1881 from 1930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 12:
The number 209 fits into 490 2 times, leaving a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 148571.2392
Subtracting 418 from 490 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 13:
If we divide 720 by 209, we get 3 and a remainder of 93.
Write down 3 as next digit of the result. 
Result so far: 148571.23923
Deduct 627 from 720 and we're left with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

On to step 14:
If we divide 930 by 209, we get 4 and a remainder of 94.
The next digit of our result is 4. 
Result so far: 148571.239234
Subtract 836 from 930 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 15:
The number 209 fits into 940 4 times, leaving a remainder of 104.
Write down 4 as next digit of the result. 
Result so far: 148571.2392344
The remainder is 104 after subtracting 836 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

The final outcome is 148571.2392344, with a leftover of 1.04e-06.
