We look at the division of 43804057 by 391 
Let's see how many times 391 fits into 43804057.

Step 1:
When dividing 4 by 391, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 391

Moving on to step 2:
43 divided by 391 is 0 with a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Append the next digit (8) from the dividend to 43 and continue with: 438 / 391

Let's proceed to step 3:
If we divide 438 by 391, we get 1 and a remainder of 47.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 391 away from 438, we end up with 47.
Take the next digit (0) from the dividend and append it to 47, then repeat: 470 / 391

Step 4:
When dividing 470 by 391, we get 1 with a remainder of 79.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 391 from 470 to get 79.
Bring next digit (4) of the dividend behind the 79 and repeat the process: 794 / 391

Moving on to step 5:
If we divide 794 by 391, we get 2 and a remainder of 12.
The next digit of our result is 2. 
Result so far: 112.0
Subtracting 782 from 794 leaves us with 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 391

Advancing to step 6:
391 can be fit into 120 0 times, resulting in a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 1120.0
Subtract 0 from 120 to get 120.
Grab the next digit (5) from the dividend, add it to 120, then carry on: 1205 / 391

Moving on to step 7:
391 goes into 1205 3 times with a remainder of 32.
Put 3 as the next digit of the answer. 
Result so far: 11203.0
Subtract 1173 from 1205 to get 32.
Grab the next digit (7) from the dividend, add it to 32, then carry on: 327 / 391

Step 8:
The number 391 fits into 327 0 times, leaving a remainder of 327.
Record the quotient 0 as the next digit in the result. 
Result so far: 112030.0
Subtracting 0 from 327 leaves us with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Step 9:
If we divide 3270 by 391, we get 8 and a remainder of 142.
The number 8 becomes the next digit in our result. 
Result so far: 112030.8
The remainder is 142 after subtracting 3128 from 3270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Step 10:
If we divide 1420 by 391, we get 3 and a remainder of 247.
Write down 3 as next digit of the result. 
Result so far: 112030.83
The remainder is 247 after subtracting 1173 from 1420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

On to step 11:
If we divide 2470 by 391, we get 6 and a remainder of 124.
Use 6 as the next digit of our solution. 
Result so far: 112030.836
If we subtract 2346 from 2470, we get 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:
391 can be fit into 1240 3 times, resulting in a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 112030.8363
If we subtract 1173 from 1240, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 13:
When dividing 670 by 391, we get 1 with a remainder of 279.
The number 1 becomes the next digit in our result. 
Result so far: 112030.83631
Deduct 391 from 670 and we're left with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Advancing to step 14:
391 goes into 2790 7 times with a remainder of 53.
The next digit of our result is 7. 
Result so far: 112030.836317
If we subtract 2737 from 2790, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 15:
If we divide 530 by 391, we get 1 and a remainder of 139.
Use 1 as the next digit of our solution. 
Result so far: 112030.8363171
Subtract 391 from 530 to get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Let's proceed to step 16:
391 can be fit into 1390 3 times, resulting in a remainder of 217.
Use 3 as the next digit of our solution. 
Result so far: 112030.83631713
Subtract 1173 from 1390 to get 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

The final outcome is 112030.83631713, with a leftover of 2.17e-07.
