We look at the division of 11991008 by 391 
We want to divide 11991008 by 391.

Advancing to step 1:
If we divide 1 by 391, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 391

Going ahead to step 2:
391 can be fit into 11 0 times, resulting in a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 11 after subtracting 0 from 11.
Include the next digit (9) from the dividend after 11, then repeat: 119 / 391

Let's proceed to step 3:
The number 391 fits into 119 0 times, leaving a remainder of 119.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 119, we end up with 119.
Bring next digit (9) of the dividend behind the 119 and repeat the process: 1199 / 391

Let's proceed to step 4:
If we divide 1199 by 391, we get 3 and a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 1173 from 1199, we get 26.
Include the next digit (1) from the dividend after 26, then repeat: 261 / 391

Going ahead to step 5:
261 divided by 391 is 0 with a remainder of 261.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
If we take 0 away from 261, we end up with 261.
Take the next digit (0) from the dividend and append it to 261, then repeat: 2610 / 391

Let's proceed to step 6:
The number 391 fits into 2610 6 times, leaving a remainder of 264.
The next digit of our result is 6. 
Result so far: 306.0
Subtract 2346 from 2610 to get 264.
Bring next digit (0) of the dividend behind the 264 and repeat the process: 2640 / 391

Moving on to step 7:
The number 391 fits into 2640 6 times, leaving a remainder of 294.
Use 6 as the next digit of our solution. 
Result so far: 3066.0
Subtract 2346 from 2640 to get 294.
Append the next digit (8) from the dividend to 294 and continue with: 2948 / 391

Going ahead to step 8:
391 goes into 2948 7 times with a remainder of 211.
The next digit of our result is 7. 
Result so far: 30667.0
If we subtract 2737 from 2948, we get 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Let's proceed to step 9:
When dividing 2110 by 391, we get 5 with a remainder of 155.
The number 5 becomes the next digit in our result. 
Result so far: 30667.5
The remainder is 155 after subtracting 1955 from 2110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Let's proceed to step 10:
The number 391 fits into 1550 3 times, leaving a remainder of 377.
The next digit of our result is 3. 
Result so far: 30667.53
Subtracting 1173 from 1550 leaves us with 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Going ahead to step 11:
391 can be fit into 3770 9 times, resulting in a remainder of 251.
Write down 9 as next digit of the result. 
Result so far: 30667.539
Subtract 3519 from 3770 to get 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Moving on to step 12:
The number 391 fits into 2510 6 times, leaving a remainder of 164.
The next digit of our result is 6. 
Result so far: 30667.5396
If we subtract 2346 from 2510, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Let's proceed to step 13:
1640 divided by 391 is 4 with a remainder of 76.
The next digit of our result is 4. 
Result so far: 30667.53964
The remainder is 76 after subtracting 1564 from 1640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 14:
When dividing 760 by 391, we get 1 with a remainder of 369.
The next digit of our result is 1. 
Result so far: 30667.539641
Deduct 391 from 760 and we're left with 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Step 15:
If we divide 3690 by 391, we get 9 and a remainder of 171.
The number 9 becomes the next digit in our result. 
Result so far: 30667.5396419
Deduct 3519 from 3690 and we're left with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Let's proceed to step 16:
1710 divided by 391 is 4 with a remainder of 146.
Record the quotient 4 as the next digit in the result. 
Result so far: 30667.53964194
Subtract 1564 from 1710 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

The final result is 30667.53964194 with a remainder of 1.46e-07.
