If we subtract 0 from 7, we get 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 393

Advancing to step 2:
When dividing 75 by 393, we get 0 with a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 75 and we're left with 75.
Bring next digit (4) of the dividend behind the 75 and repeat the process: 754 / 393

Let's proceed to step 3:
754 divided by 393 is 1 with a remainder of 361.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 393 from 754 to get 361.
Append the next digit (0) from the dividend to 361 and continue with: 3610 / 393

Let's proceed to step 4:
3610 divided by 393 is 9 with a remainder of 73.
The next digit of our result is 9. 
Result so far: 19.0
Deduct 3537 from 3610 and we're left with 73.
Bring next digit (5) of the dividend behind the 73 and repeat the process: 735 / 393

Advancing to step 5:
The number 393 fits into 735 1 times, leaving a remainder of 342.
Write down 1 as next digit of the result. 
Result so far: 191.0
If we subtract 393 from 735, we get 342.
Append the next digit (6) from the dividend to 342 and continue with: 3426 / 393

Moving on to step 6:
3426 divided by 393 is 8 with a remainder of 282.
The number 8 becomes the next digit in our result. 
Result so far: 1918.0
The remainder is 282 after subtracting 3144 from 3426.
Append the next digit (4) from the dividend to 282 and continue with: 2824 / 393

Going ahead to step 7:
If we divide 2824 by 393, we get 7 and a remainder of 73.
Write down 7 as next digit of the result. 
Result so far: 19187.0
Subtract 2751 from 2824 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 8:
730 divided by 393 is 1 with a remainder of 337.
Write down 1 as next digit of the result. 
Result so far: 19187.1
Deduct 393 from 730 and we're left with 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Let's proceed to step 9:
When dividing 3370 by 393, we get 8 with a remainder of 226.
Record the quotient 8 as the next digit in the result. 
Result so far: 19187.18
If we subtract 3144 from 3370, we get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Going ahead to step 10:
If we divide 2260 by 393, we get 5 and a remainder of 295.
Record the quotient 5 as the next digit in the result. 
Result so far: 19187.185
Deduct 1965 from 2260 and we're left with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Let's proceed to step 11:
The number 393 fits into 2950 7 times, leaving a remainder of 199.
Put 7 as the next digit of the answer. 
Result so far: 19187.1857
Subtract 2751 from 2950 to get 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Moving on to step 12:
1990 divided by 393 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 19187.18575
If we subtract 1965 from 1990, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 13:
When dividing 250 by 393, we get 0 with a remainder of 250.
The number 0 becomes the next digit in our result. 
Result so far: 19187.18575
Subtract 0 from 250 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 14:
393 can be fit into 2500 6 times, resulting in a remainder of 142.
Put 6 as the next digit of the answer. 
Result so far: 19187.1857506
The remainder is 142 after subtracting 2358 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Let's proceed to step 15:
The number 393 fits into 1420 3 times, leaving a remainder of 241.
The next digit of our result is 3. 
Result so far: 19187.18575063
Subtracting 1179 from 1420 leaves us with 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

In conclusion, the division gives 19187.18575063 with a balance of 2.41e-07.
