801479 ÷ 12 
Let's see how many times 12 fits into 801479.

Going ahead to step 1:
12 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our 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

Moving on to step 2:
If we divide 80 by 12, we get 6 and a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 72 away from 80, we end up with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 12

Going ahead to step 3:
81 divided by 12 is 6 with a remainder of 9.
The next digit of our result is 6. 
Result so far: 66.0
Subtracting 72 from 81 leaves us with 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 12

On to step 4:
The number 12 fits into 94 7 times, leaving a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 667.0
Subtracting 84 from 94 leaves us with 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 12

Going ahead to step 5:
12 goes into 107 8 times with a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 6678.0
If we take 96 away from 107, we end up with 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 12

Advancing to step 6:
When dividing 119 by 12, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 66789.0
Subtract 108 from 119 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
110 divided by 12 is 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 66789.9
Subtracting 108 from 110 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
The number 12 fits into 20 1 times, leaving a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 66789.91
Subtract 12 from 20 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
When dividing 80 by 12, we get 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 66789.916
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
When dividing 80 by 12, we get 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 66789.9166
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 66789.9166, with a leftover of 8e-05.
