805749 ÷ 12 
Our goal is to divide 805749 by 12.

Step 1:
12 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 12

Going ahead to step 2:
12 goes into 80 6 times with a remainder of 8.
The next digit of our result is 6. 
Result so far: 6.0
If we take 72 away from 80, we end up with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 12

Step 3:
85 divided by 12 is 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 67.0
Subtracting 84 from 85 leaves us with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 12

Step 4:
If we divide 17 by 12, we get 1 and a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 671.0
The remainder is 5 after subtracting 12 from 17.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 12

Let's proceed to step 5:
If we divide 54 by 12, we get 4 and a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 6714.0
Subtracting 48 from 54 leaves us with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 12

Going ahead to step 6:
12 goes into 69 5 times with a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 67145.0
Subtracting 60 from 69 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
12 goes into 90 7 times with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 67145.7
Subtract 84 from 90 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
12 can be fit into 60 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 67145.75
The remainder is 0 after subtracting 60 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
If we divide 0 by 12, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 67145.75
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
12 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 67145.75
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 67145.75, with a leftover of 0.0.
