We look at the division of 57346381 by 391 
We want to divide 57346381 by 391.

Going ahead to step 1:
When dividing 5 by 391, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 391

Advancing to step 2:
The number 391 fits into 57 0 times, leaving a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Include the next digit (3) from the dividend after 57, then repeat: 573 / 391

Advancing to step 3:
If we divide 573 by 391, we get 1 and a remainder of 182.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 391 from 573 leaves us with 182.
Fetch the next digit (4) from the dividend, attach it to 182 and continue: 1824 / 391

Going ahead to step 4:
391 goes into 1824 4 times with a remainder of 260.
The next digit of our result is 4. 
Result so far: 14.0
Subtract 1564 from 1824 to get 260.
Bring next digit (6) of the dividend behind the 260 and repeat the process: 2606 / 391

Step 5:
2606 divided by 391 is 6 with a remainder of 260.
The number 6 becomes the next digit in our result. 
Result so far: 146.0
Subtracting 2346 from 2606 leaves us with 260.
Take the next digit (3) from the dividend and append it to 260, then repeat: 2603 / 391

On to step 6:
391 goes into 2603 6 times with a remainder of 257.
Use 6 as the next digit of our solution. 
Result so far: 1466.0
If we take 2346 away from 2603, we end up with 257.
Bring next digit (8) of the dividend behind the 257 and repeat the process: 2578 / 391

Advancing to step 7:
The number 391 fits into 2578 6 times, leaving a remainder of 232.
Use 6 as the next digit of our solution. 
Result so far: 14666.0
Subtracting 2346 from 2578 leaves us with 232.
Grab the next digit (1) from the dividend, add it to 232, then carry on: 2321 / 391

Going ahead to step 8:
If we divide 2321 by 391, we get 5 and a remainder of 366.
The number 5 becomes the next digit in our result. 
Result so far: 146665.0
The remainder is 366 after subtracting 1955 from 2321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Let's proceed to step 9:
When dividing 3660 by 391, we get 9 with a remainder of 141.
Use 9 as the next digit of our solution. 
Result so far: 146665.9
If we subtract 3519 from 3660, we get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Let's proceed to step 10:
391 can be fit into 1410 3 times, resulting in a remainder of 237.
Put 3 as the next digit of the answer. 
Result so far: 146665.93
Subtracting 1173 from 1410 leaves us with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

On to step 11:
2370 divided by 391 is 6 with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 146665.936
If we subtract 2346 from 2370, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 12:
240 divided by 391 is 0 with a remainder of 240.
The next digit of our result is 0. 
Result so far: 146665.936
If we take 0 away from 240, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 13:
2400 divided by 391 is 6 with a remainder of 54.
The next digit of our result is 6. 
Result so far: 146665.93606
The remainder is 54 after subtracting 2346 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 14:
The number 391 fits into 540 1 times, leaving a remainder of 149.
Write down 1 as next digit of the result. 
Result so far: 146665.936061
Subtract 391 from 540 to get 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Advancing to step 15:
1490 divided by 391 is 3 with a remainder of 317.
Use 3 as the next digit of our solution. 
Result so far: 146665.9360613
If we subtract 1173 from 1490, we get 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Going ahead to step 16:
When dividing 3170 by 391, we get 8 with a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 146665.93606138
Subtracting 3128 from 3170 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final result is 146665.93606138 with a remainder of 4.2e-08.
