Let's divide 12766954 by 799
Let's see how many times 799 fits into 12766954.

Let's proceed to step 1:
799 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 799

Moving on to step 2:
If we divide 12 by 799, we get 0 and a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Bring next digit (7) of the dividend behind the 12 and repeat the process: 127 / 799

Let's proceed to step 3:
The number 799 fits into 127 0 times, leaving a remainder of 127.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 127 after subtracting 0 from 127.
Include the next digit (6) from the dividend after 127, then repeat: 1276 / 799

Moving on to step 4:
When dividing 1276 by 799, we get 1 with a remainder of 477.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 799 from 1276 leaves us with 477.
Include the next digit (6) from the dividend after 477, then repeat: 4776 / 799

Moving on to step 5:
The number 799 fits into 4776 5 times, leaving a remainder of 781.
The next digit of our result is 5. 
Result so far: 15.0
If we take 3995 away from 4776, we end up with 781.
Include the next digit (9) from the dividend after 781, then repeat: 7819 / 799

Moving on to step 6:
799 goes into 7819 9 times with a remainder of 628.
Put 9 as the next digit of the answer. 
Result so far: 159.0
Subtract 7191 from 7819 to get 628.
Append the next digit (5) from the dividend to 628 and continue with: 6285 / 799

Let's proceed to step 7:
The number 799 fits into 6285 7 times, leaving a remainder of 692.
Write down 7 as next digit of the result. 
Result so far: 1597.0
If we take 5593 away from 6285, we end up with 692.
Take the next digit (4) from the dividend and append it to 692, then repeat: 6924 / 799

Moving on to step 8:
The number 799 fits into 6924 8 times, leaving a remainder of 532.
Use 8 as the next digit of our solution. 
Result so far: 15978.0
Deduct 6392 from 6924 and we're left with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Advancing to step 9:
799 goes into 5320 6 times with a remainder of 526.
Put 6 as the next digit of the answer. 
Result so far: 15978.6
If we take 4794 away from 5320, we end up with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Going ahead to step 10:
The number 799 fits into 5260 6 times, leaving a remainder of 466.
Use 6 as the next digit of our solution. 
Result so far: 15978.66
Subtracting 4794 from 5260 leaves us with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

The final outcome is 15978.66, with a leftover of 0.466.
