Let's divide 40577256 by 391
Our goal is to divide 40577256 by 391.

Moving on to step 1:
When dividing 4 by 391, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 391

Step 2:
The number 391 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Include the next digit (5) from the dividend after 40, then repeat: 405 / 391

On to step 3:
391 goes into 405 1 times with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 391 from 405 to get 14.
Bring next digit (7) of the dividend behind the 14 and repeat the process: 147 / 391

On to step 4:
391 can be fit into 147 0 times, resulting in a remainder of 147.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 147 and we're left with 147.
Bring next digit (7) of the dividend behind the 147 and repeat the process: 1477 / 391

Moving on to step 5:
When dividing 1477 by 391, we get 3 with a remainder of 304.
The next digit of our result is 3. 
Result so far: 103.0
The remainder is 304 after subtracting 1173 from 1477.
Take the next digit (2) from the dividend and append it to 304, then repeat: 3042 / 391

Advancing to step 6:
The number 391 fits into 3042 7 times, leaving a remainder of 305.
The next digit of our result is 7. 
Result so far: 1037.0
Deduct 2737 from 3042 and we're left with 305.
Fetch the next digit (5) from the dividend, attach it to 305 and continue: 3055 / 391

Step 7:
The number 391 fits into 3055 7 times, leaving a remainder of 318.
The next digit of our result is 7. 
Result so far: 10377.0
Subtract 2737 from 3055 to get 318.
Include the next digit (6) from the dividend after 318, then repeat: 3186 / 391

Let's proceed to step 8:
3186 divided by 391 is 8 with a remainder of 58.
The next digit of our result is 8. 
Result so far: 103778.0
Subtracting 3128 from 3186 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 9:
391 can be fit into 580 1 times, resulting in a remainder of 189.
Write down 1 as next digit of the result. 
Result so far: 103778.1
The remainder is 189 after subtracting 391 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

On to step 10:
The number 391 fits into 1890 4 times, leaving a remainder of 326.
Record the quotient 4 as the next digit in the result. 
Result so far: 103778.14
The remainder is 326 after subtracting 1564 from 1890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

On to step 11:
When dividing 3260 by 391, we get 8 with a remainder of 132.
The next digit of our result is 8. 
Result so far: 103778.148
If we take 3128 away from 3260, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 12:
When dividing 1320 by 391, we get 3 with a remainder of 147.
Put 3 as the next digit of the answer. 
Result so far: 103778.1483
Subtracting 1173 from 1320 leaves us with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Moving on to step 13:
391 can be fit into 1470 3 times, resulting in a remainder of 297.
Write down 3 as next digit of the result. 
Result so far: 103778.14833
If we take 1173 away from 1470, we end up with 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

The final result is 103778.14833 with a remainder of 0.000297.
