Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 393

Step 2:
When dividing 12 by 393, we get 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 393

Advancing to step 3:
393 can be fit into 124 0 times, resulting in a remainder of 124.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 124, we get 124.
Fetch the next digit (1) from the dividend, attach it to 124 and continue: 1241 / 393

On to step 4:
The number 393 fits into 1241 3 times, leaving a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 1179 from 1241 leaves us with 62.
Fetch the next digit (1) from the dividend, attach it to 62 and continue: 621 / 393

On to step 5:
393 can be fit into 621 1 times, resulting in a remainder of 228.
The next digit of our result is 1. 
Result so far: 31.0
The remainder is 228 after subtracting 393 from 621.
Fetch the next digit (3) from the dividend, attach it to 228 and continue: 2283 / 393

Moving on to step 6:
The number 393 fits into 2283 5 times, leaving a remainder of 318.
Use 5 as the next digit of our solution. 
Result so far: 315.0
If we subtract 1965 from 2283, we get 318.
Grab the next digit (8) from the dividend, add it to 318, then carry on: 3188 / 393

On to step 7:
The number 393 fits into 3188 8 times, leaving a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 3158.0
Subtract 3144 from 3188 to get 44.
Bring next digit (5) of the dividend behind the 44 and repeat the process: 445 / 393

Advancing to step 8:
393 can be fit into 445 1 times, resulting in a remainder of 52.
The number 1 becomes the next digit in our result. 
Result so far: 31581.0
Subtract 393 from 445 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 9:
If we divide 520 by 393, we get 1 and a remainder of 127.
Use 1 as the next digit of our solution. 
Result so far: 31581.1
The remainder is 127 after subtracting 393 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Let's proceed to step 10:
When dividing 1270 by 393, we get 3 with a remainder of 91.
Put 3 as the next digit of the answer. 
Result so far: 31581.13
Subtract 1179 from 1270 to get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Step 11:
If we divide 910 by 393, we get 2 and a remainder of 124.
Record the quotient 2 as the next digit in the result. 
Result so far: 31581.132
If we take 786 away from 910, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 12:
393 can be fit into 1240 3 times, resulting in a remainder of 61.
Put 3 as the next digit of the answer. 
Result so far: 31581.1323
Subtracting 1179 from 1240 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 13:
When dividing 610 by 393, we get 1 with a remainder of 217.
Put 1 as the next digit of the answer. 
Result so far: 31581.13231
The remainder is 217 after subtracting 393 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Advancing to step 14:
If we divide 2170 by 393, we get 5 and a remainder of 205.
Put 5 as the next digit of the answer. 
Result so far: 31581.132315
Deduct 1965 from 2170 and we're left with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Let's proceed to step 15:
The number 393 fits into 2050 5 times, leaving a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 31581.1323155
The remainder is 85 after subtracting 1965 from 2050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

The final result is 31581.1323155 with a remainder of 8.5e-07.
