Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 390

Moving on to step 5:
If we divide 1 by 390, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 60.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 390

Moving on to step 6:
390 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 600.0
Deduct 0 from 10 and we're left with 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 390

Let's proceed to step 7:
When dividing 106 by 390, we get 0 with a remainder of 106.
The next digit of our result is 0. 
Result so far: 6000.0
Subtracting 0 from 106 leaves us with 106.
Fetch the next digit (7) from the dividend, attach it to 106 and continue: 1067 / 390

Moving on to step 8:
The number 390 fits into 1067 2 times, leaving a remainder of 287.
Write down 2 as next digit of the result. 
Result so far: 60002.0
If we take 780 away from 1067, we end up with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Step 9:
When dividing 2870 by 390, we get 7 with a remainder of 140.
Put 7 as the next digit of the answer. 
Result so far: 60002.7
If we take 2730 away from 2870, 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.

On to step 10:
The number 390 fits into 1400 3 times, leaving a remainder of 230.
Put 3 as the next digit of the answer. 
Result so far: 60002.73
If we take 1170 away from 1400, we end up 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.

Let's proceed to step 11:
If we divide 2300 by 390, we get 5 and a remainder of 350.
Write down 5 as next digit of the result. 
Result so far: 60002.735
Subtracting 1950 from 2300 leaves us with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 12:
The number 390 fits into 3500 8 times, leaving a remainder of 380.
Use 8 as the next digit of our solution. 
Result so far: 60002.7358
If we subtract 3120 from 3500, we get 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 13:
390 goes into 3800 9 times with a remainder of 290.
Use 9 as the next digit of our solution. 
Result so far: 60002.73589
Subtracting 3510 from 3800 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 14:
When dividing 2900 by 390, we get 7 with a remainder of 170.
The next digit of our result is 7. 
Result so far: 60002.735897
Subtracting 2730 from 2900 leaves us 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.

Going ahead to step 15:
390 can be fit into 1700 4 times, resulting in a remainder of 140.
The next digit of our result is 4. 
Result so far: 60002.7358974
Deduct 1560 from 1700 and we're left 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.

On to step 16:
The number 390 fits into 1400 3 times, leaving a remainder of 230.
Record the quotient 3 as the next digit in the result. 
Result so far: 60002.73589743
If we take 1170 away from 1400, we end up 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.
