Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 390

Advancing to step 2:
390 goes into 52 0 times with a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Fetch the next digit (2) from the dividend, attach it to 52 and continue: 522 / 390

Step 3:
390 goes into 522 1 times with a remainder of 132.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 390 from 522 and we're left with 132.
Include the next digit (8) from the dividend after 132, then repeat: 1328 / 390

Moving on to step 4:
The number 390 fits into 1328 3 times, leaving a remainder of 158.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 1170 from 1328 to get 158.
Grab the next digit (3) from the dividend, add it to 158, then carry on: 1583 / 390

Moving on to step 5:
When dividing 1583 by 390, we get 4 with a remainder of 23.
Put 4 as the next digit of the answer. 
Result so far: 134.0
Subtract 1560 from 1583 to get 23.
Include the next digit (3) from the dividend after 23, then repeat: 233 / 390

Step 6:
The number 390 fits into 233 0 times, leaving a remainder of 233.
Use 0 as the next digit of our solution. 
Result so far: 1340.0
Subtract 0 from 233 to get 233.
Fetch the next digit (7) from the dividend, attach it to 233 and continue: 2337 / 390

Moving on to step 7:
390 can be fit into 2337 5 times, resulting in a remainder of 387.
The next digit of our result is 5. 
Result so far: 13405.0
Subtracting 1950 from 2337 leaves us with 387.
Include the next digit (3) from the dividend after 387, then repeat: 3873 / 390

Let's proceed to step 8:
The number 390 fits into 3873 9 times, leaving a remainder of 363.
Put 9 as the next digit of the answer. 
Result so far: 134059.0
Subtracting 3510 from 3873 leaves us with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Advancing to step 9:
390 goes into 3630 9 times with a remainder of 120.
The next digit of our result is 9. 
Result so far: 134059.9
Subtract 3510 from 3630 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 10:
390 can be fit into 1200 3 times, resulting in a remainder of 30.
The next digit of our result is 3. 
Result so far: 134059.93
Subtracting 1170 from 1200 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 11:
The number 390 fits into 300 0 times, leaving a remainder of 300.
Write down 0 as next digit of the result. 
Result so far: 134059.93
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 12:
3000 divided by 390 is 7 with a remainder of 270.
Put 7 as the next digit of the answer. 
Result so far: 134059.9307
Subtracting 2730 from 3000 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 13:
When dividing 2700 by 390, we get 6 with a remainder of 360.
Use 6 as the next digit of our solution. 
Result so far: 134059.93076
If we subtract 2340 from 2700, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 14:
390 goes into 3600 9 times with a remainder of 90.
Use 9 as the next digit of our solution. 
Result so far: 134059.930769
If we subtract 3510 from 3600, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 15:
390 can be fit into 900 2 times, resulting in a remainder of 120.
Put 2 as the next digit of the answer. 
Result so far: 134059.9307692
The remainder is 120 after subtracting 780 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 16:
When dividing 1200 by 390, we get 3 with a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 134059.93076923
The remainder is 30 after subtracting 1170 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 134059.93076923, and the remainder is 3e-08.
