When dividing 2 by 939, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 939

Step 2:
21 divided by 939 is 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Take the next digit (7) from the dividend and append it to 21, then repeat: 217 / 939

Step 3:
When dividing 217 by 939, we get 0 with a remainder of 217.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 217 to get 217.
Bring next digit (8) of the dividend behind the 217 and repeat the process: 2178 / 939

On to step 4:
939 can be fit into 2178 2 times, resulting in a remainder of 300.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 1878 from 2178 to get 300.
Bring next digit (6) of the dividend behind the 300 and repeat the process: 3006 / 939

Moving on to step 5:
939 goes into 3006 3 times with a remainder of 189.
Put 3 as the next digit of the answer. 
Result so far: 23.0
If we subtract 2817 from 3006, we get 189.
Bring next digit (3) of the dividend behind the 189 and repeat the process: 1893 / 939

Moving on to step 6:
1893 divided by 939 is 2 with a remainder of 15.
Write down 2 as next digit of the result. 
Result so far: 232.0
Subtract 1878 from 1893 to get 15.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 939

Going ahead to step 7:
The number 939 fits into 153 0 times, leaving a remainder of 153.
Put 0 as the next digit of the answer. 
Result so far: 2320.0
Subtracting 0 from 153 leaves us with 153.
Take the next digit (4) from the dividend and append it to 153, then repeat: 1534 / 939

Going ahead to step 8:
939 can be fit into 1534 1 times, resulting in a remainder of 595.
Record the quotient 1 as the next digit in the result. 
Result so far: 23201.0
Subtract 939 from 1534 to get 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Step 9:
When dividing 5950 by 939, we get 6 with a remainder of 316.
Record the quotient 6 as the next digit in the result. 
Result so far: 23201.6
Deduct 5634 from 5950 and we're left with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

On to step 10:
If we divide 3160 by 939, we get 3 and a remainder of 343.
The number 3 becomes the next digit in our result. 
Result so far: 23201.63
Subtract 2817 from 3160 to get 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Moving on to step 11:
3430 divided by 939 is 3 with a remainder of 613.
The number 3 becomes the next digit in our result. 
Result so far: 23201.633
If we subtract 2817 from 3430, we get 613.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6130, and continue the process.

Our division results in 23201.633 with a remaining 0.0613.
