Advancing to step 1:
3 divided by 391 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 391

Moving on to step 2:
391 goes into 31 0 times with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Fetch the next digit (2) from the dividend, attach it to 31 and continue: 312 / 391

Going ahead to step 3:
312 divided by 391 is 0 with a remainder of 312.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 312 leaves us with 312.
Append the next digit (9) from the dividend to 312 and continue with: 3129 / 391

Going ahead to step 4:
3129 divided by 391 is 8 with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 1 after subtracting 3128 from 3129.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 391

Step 5:
391 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 80.0
Subtracting 0 from 12 leaves us with 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 391

Going ahead to step 6:
391 goes into 120 0 times with a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 800.0
Deduct 0 from 120 and we're left with 120.
Append the next digit (8) from the dividend to 120 and continue with: 1208 / 391

Going ahead to step 7:
1208 divided by 391 is 3 with a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 8003.0
Subtracting 1173 from 1208 leaves us with 35.
Include the next digit (3) from the dividend after 35, then repeat: 353 / 391

Going ahead to step 8:
391 goes into 353 0 times with a remainder of 353.
Record the quotient 0 as the next digit in the result. 
Result so far: 80030.0
The remainder is 353 after subtracting 0 from 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Advancing to step 9:
3530 divided by 391 is 9 with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 80030.9
Subtract 3519 from 3530 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 10:
When dividing 110 by 391, we get 0 with a remainder of 110.
Use 0 as the next digit of our solution. 
Result so far: 80030.9
If we subtract 0 from 110, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 11:
391 can be fit into 1100 2 times, resulting in a remainder of 318.
Record the quotient 2 as the next digit in the result. 
Result so far: 80030.902
Subtract 782 from 1100 to get 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Step 12:
3180 divided by 391 is 8 with a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 80030.9028
Subtracting 3128 from 3180 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 13:
The number 391 fits into 520 1 times, leaving a remainder of 129.
Put 1 as the next digit of the answer. 
Result so far: 80030.90281
The remainder is 129 after subtracting 391 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Moving on to step 14:
391 goes into 1290 3 times with a remainder of 117.
Record the quotient 3 as the next digit in the result. 
Result so far: 80030.902813
If we subtract 1173 from 1290, we get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Advancing to step 15:
When dividing 1170 by 391, we get 2 with a remainder of 388.
Put 2 as the next digit of the answer. 
Result so far: 80030.9028132
The remainder is 388 after subtracting 782 from 1170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Moving on to step 16:
When dividing 3880 by 391, we get 9 with a remainder of 361.
Write down 9 as next digit of the result. 
Result so far: 80030.90281329
If we take 3519 away from 3880, we end up with 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Our division results in 80030.90281329 with a remaining 3.61e-07.
