2 divided by 103 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 103

Moving on to step 2:
When dividing 21 by 103, we get 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Grab the next digit (6) from the dividend, add it to 21, then carry on: 216 / 103

Moving on to step 3:
If we divide 216 by 103, we get 2 and a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 206 from 216, we get 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 103

Step 4:
When dividing 100 by 103, we get 0 with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtract 0 from 100 to get 100.
Bring next digit (9) of the dividend behind the 100 and repeat the process: 1009 / 103

Advancing to step 5:
103 can be fit into 1009 9 times, resulting in a remainder of 82.
The number 9 becomes the next digit in our result. 
Result so far: 209.0
The remainder is 82 after subtracting 927 from 1009.
Bring next digit (2) of the dividend behind the 82 and repeat the process: 822 / 103

Advancing to step 6:
The number 103 fits into 822 7 times, leaving a remainder of 101.
Use 7 as the next digit of our solution. 
Result so far: 2097.0
Deduct 721 from 822 and we're left with 101.
Append the next digit (8) from the dividend to 101 and continue with: 1018 / 103

On to step 7:
103 can be fit into 1018 9 times, resulting in a remainder of 91.
Write down 9 as next digit of the result. 
Result so far: 20979.0
Deduct 927 from 1018 and we're left with 91.
Grab the next digit (5) from the dividend, add it to 91, then carry on: 915 / 103

Going ahead to step 8:
103 can be fit into 915 8 times, resulting in a remainder of 91.
Use 8 as the next digit of our solution. 
Result so far: 209798.0
Deduct 824 from 915 and we're left with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Step 9:
910 divided by 103 is 8 with a remainder of 86.
The next digit of our result is 8. 
Result so far: 209798.8
Deduct 824 from 910 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 10:
860 divided by 103 is 8 with a remainder of 36.
The next digit of our result is 8. 
Result so far: 209798.88
Deduct 824 from 860 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 209798.88, with a leftover of 0.036.
