873263 ÷ 12 
Let's see how many times 12 fits into 873263.

Moving on to step 1:
If we divide 8 by 12, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 12

Step 2:
12 can be fit into 87 7 times, resulting in a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 84 from 87, we get 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 12

Moving on to step 3:
When dividing 33 by 12, we get 2 with a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 72.0
If we subtract 24 from 33, we get 9.
Bring next digit (2) of the dividend behind the 9 and repeat the process: 92 / 12

Let's proceed to step 4:
The number 12 fits into 92 7 times, leaving a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 727.0
Deduct 84 from 92 and we're left with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 12

Step 5:
When dividing 86 by 12, we get 7 with a remainder of 2.
The next digit of our result is 7. 
Result so far: 7277.0
If we subtract 84 from 86, we get 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 12

On to step 6:
23 divided by 12 is 1 with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 72771.0
Subtracting 12 from 23 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
12 can be fit into 110 9 times, resulting in a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 72771.9
Deduct 108 from 110 and we're left 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.

Going ahead to step 8:
If we divide 20 by 12, we get 1 and a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 72771.91
If we subtract 12 from 20, we 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.

Moving on to step 9:
If we divide 80 by 12, we get 6 and a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 72771.916
If we subtract 72 from 80, we 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.

Going ahead to step 10:
80 divided by 12 is 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 72771.9166
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 72771.9166, with a leftover of 8e-05.
