Let's proceed to step 1:
390 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 390

Going ahead to step 2:
390 goes into 21 0 times with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 390

Going ahead to step 3:
When dividing 218 by 390, we get 0 with a remainder of 218.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 218 leaves us with 218.
Fetch the next digit (0) from the dividend, attach it to 218 and continue: 2180 / 390

Moving on to step 4:
The number 390 fits into 2180 5 times, leaving a remainder of 230.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 1950 from 2180 to get 230.
Include the next digit (3) from the dividend after 230, then repeat: 2303 / 390

On to step 5:
If we divide 2303 by 390, we get 5 and a remainder of 353.
Write down 5 as next digit of the result. 
Result so far: 55.0
Subtracting 1950 from 2303 leaves us with 353.
Take the next digit (1) from the dividend and append it to 353, then repeat: 3531 / 390

Going ahead to step 6:
390 can be fit into 3531 9 times, resulting in a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 559.0
If we take 3510 away from 3531, we end up with 21.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 390

Advancing to step 7:
The number 390 fits into 213 0 times, leaving a remainder of 213.
Put 0 as the next digit of the answer. 
Result so far: 5590.0
The remainder is 213 after subtracting 0 from 213.
Grab the next digit (5) from the dividend, add it to 213, then carry on: 2135 / 390

Step 8:
The number 390 fits into 2135 5 times, leaving a remainder of 185.
Use 5 as the next digit of our solution. 
Result so far: 55905.0
If we subtract 1950 from 2135, we get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 9:
The number 390 fits into 1850 4 times, leaving a remainder of 290.
Write down 4 as next digit of the result. 
Result so far: 55905.4
If we subtract 1560 from 1850, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Moving on to step 10:
When dividing 2900 by 390, we get 7 with a remainder of 170.
Write down 7 as next digit of the result. 
Result so far: 55905.47
If we take 2730 away from 2900, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 11:
390 can be fit into 1700 4 times, resulting in a remainder of 140.
Write down 4 as next digit of the result. 
Result so far: 55905.474
If we take 1560 away from 1700, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 12:
390 goes into 1400 3 times with a remainder of 230.
Use 3 as the next digit of our solution. 
Result so far: 55905.4743
Deduct 1170 from 1400 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 13:
When dividing 2300 by 390, we get 5 with a remainder of 350.
The number 5 becomes the next digit in our result. 
Result so far: 55905.47435
Subtract 1950 from 2300 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Moving on to step 14:
If we divide 3500 by 390, we get 8 and a remainder of 380.
The next digit of our result is 8. 
Result so far: 55905.474358
Subtracting 3120 from 3500 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.

Going ahead to step 15:
390 can be fit into 3800 9 times, resulting in a remainder of 290.
Use 9 as the next digit of our solution. 
Result so far: 55905.4743589
Subtract 3510 from 3800 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Moving on to step 16:
390 goes into 2900 7 times with a remainder of 170.
The next digit of our result is 7. 
Result so far: 55905.47435897
Subtract 2730 from 2900 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

The final result is 55905.47435897 with a remainder of 1.7e-07.
