Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 393

Going ahead to step 2:
31 divided by 393 is 0 with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Append the next digit (5) from the dividend to 31 and continue with: 315 / 393

Moving on to step 3:
When dividing 315 by 393, we get 0 with a remainder of 315.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 315, we get 315.
Append the next digit (7) from the dividend to 315 and continue with: 3157 / 393

Let's proceed to step 4:
3157 divided by 393 is 8 with a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 3144 from 3157, we get 13.
Append the next digit (7) from the dividend to 13 and continue with: 137 / 393

Advancing to step 5:
The number 393 fits into 137 0 times, leaving a remainder of 137.
The next digit of our result is 0. 
Result so far: 80.0
Subtracting 0 from 137 leaves us with 137.
Bring next digit (3) of the dividend behind the 137 and repeat the process: 1373 / 393

On to step 6:
When dividing 1373 by 393, we get 3 with a remainder of 194.
Write down 3 as next digit of the result. 
Result so far: 803.0
Subtract 1179 from 1373 to get 194.
Fetch the next digit (0) from the dividend, attach it to 194 and continue: 1940 / 393

On to step 7:
1940 divided by 393 is 4 with a remainder of 368.
Record the quotient 4 as the next digit in the result. 
Result so far: 8034.0
If we subtract 1572 from 1940, we get 368.
Fetch the next digit (0) from the dividend, attach it to 368 and continue: 3680 / 393

On to step 8:
393 goes into 3680 9 times with a remainder of 143.
The number 9 becomes the next digit in our result. 
Result so far: 80349.0
Subtract 3537 from 3680 to get 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Going ahead to step 9:
When dividing 1430 by 393, we get 3 with a remainder of 251.
Put 3 as the next digit of the answer. 
Result so far: 80349.3
The remainder is 251 after subtracting 1179 from 1430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Step 10:
2510 divided by 393 is 6 with a remainder of 152.
Put 6 as the next digit of the answer. 
Result so far: 80349.36
If we subtract 2358 from 2510, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 11:
393 goes into 1520 3 times with a remainder of 341.
Use 3 as the next digit of our solution. 
Result so far: 80349.363
Subtract 1179 from 1520 to get 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Moving on to step 12:
The number 393 fits into 3410 8 times, leaving a remainder of 266.
The next digit of our result is 8. 
Result so far: 80349.3638
Subtracting 3144 from 3410 leaves us with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Going ahead to step 13:
393 can be fit into 2660 6 times, resulting in a remainder of 302.
Put 6 as the next digit of the answer. 
Result so far: 80349.36386
If we subtract 2358 from 2660, we get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Moving on to step 14:
3020 divided by 393 is 7 with a remainder of 269.
Use 7 as the next digit of our solution. 
Result so far: 80349.363867
The remainder is 269 after subtracting 2751 from 3020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Step 15:
When dividing 2690 by 393, we get 6 with a remainder of 332.
Write down 6 as next digit of the result. 
Result so far: 80349.3638676
The remainder is 332 after subtracting 2358 from 2690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Going ahead to step 16:
When dividing 3320 by 393, we get 8 with a remainder of 176.
The number 8 becomes the next digit in our result. 
Result so far: 80349.36386768
The remainder is 176 after subtracting 3144 from 3320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

The final result is 80349.36386768 with a remainder of 1.76e-07.
