Let's divide 8180216 by 391
Let's see how many times 391 fits into 8180216.

Going ahead to step 1:
When dividing 8 by 391, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 391

Let's proceed to step 2:
81 divided by 391 is 0 with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Take the next digit (8) from the dividend and append it to 81, then repeat: 818 / 391

Going ahead to step 3:
If we divide 818 by 391, we get 2 and a remainder of 36.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 782 from 818 to get 36.
Include the next digit (0) from the dividend after 36, then repeat: 360 / 391

Advancing to step 4:
The number 391 fits into 360 0 times, leaving a remainder of 360.
Write down 0 as next digit of the result. 
Result so far: 20.0
The remainder is 360 after subtracting 0 from 360.
Include the next digit (2) from the dividend after 360, then repeat: 3602 / 391

Moving on to step 5:
When dividing 3602 by 391, we get 9 with a remainder of 83.
The next digit of our result is 9. 
Result so far: 209.0
The remainder is 83 after subtracting 3519 from 3602.
Fetch the next digit (1) from the dividend, attach it to 83 and continue: 831 / 391

Moving on to step 6:
The number 391 fits into 831 2 times, leaving a remainder of 49.
The number 2 becomes the next digit in our result. 
Result so far: 2092.0
Deduct 782 from 831 and we're left with 49.
Include the next digit (6) from the dividend after 49, then repeat: 496 / 391

Advancing to step 7:
The number 391 fits into 496 1 times, leaving a remainder of 105.
Write down 1 as next digit of the result. 
Result so far: 20921.0
If we subtract 391 from 496, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 8:
The number 391 fits into 1050 2 times, leaving a remainder of 268.
Use 2 as the next digit of our solution. 
Result so far: 20921.2
Subtract 782 from 1050 to get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Moving on to step 9:
391 can be fit into 2680 6 times, resulting in a remainder of 334.
Write down 6 as next digit of the result. 
Result so far: 20921.26
If we take 2346 away from 2680, we end up with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

On to step 10:
If we divide 3340 by 391, we get 8 and a remainder of 212.
Put 8 as the next digit of the answer. 
Result so far: 20921.268
If we take 3128 away from 3340, we end up with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Step 11:
When dividing 2120 by 391, we get 5 with a remainder of 165.
The next digit of our result is 5. 
Result so far: 20921.2685
The remainder is 165 after subtracting 1955 from 2120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Let's proceed to step 12:
The number 391 fits into 1650 4 times, leaving a remainder of 86.
Put 4 as the next digit of the answer. 
Result so far: 20921.26854
Deduct 1564 from 1650 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 13:
If we divide 860 by 391, we get 2 and a remainder of 78.
The number 2 becomes the next digit in our result. 
Result so far: 20921.268542
Subtracting 782 from 860 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 14:
The number 391 fits into 780 1 times, leaving a remainder of 389.
Write down 1 as next digit of the result. 
Result so far: 20921.2685421
Subtracting 391 from 780 leaves us with 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Step 15:
When dividing 3890 by 391, we get 9 with a remainder of 371.
Record the quotient 9 as the next digit in the result. 
Result so far: 20921.26854219
If we take 3519 away from 3890, we end up with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

The final outcome is 20921.26854219, with a leftover of 3.71e-07.
