We're dividing 10405823 by 12 
We're looking to find how many times 12 goes into 10405823.

Let's proceed to step 1:
When dividing 1 by 12, we get 0 with 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.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 12

Let's proceed to step 2:
When dividing 10 by 12, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 12

Advancing to step 3:
When dividing 104 by 12, we get 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 96 from 104 leaves us with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 12

Going ahead to step 4:
12 goes into 80 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 86.0
Deduct 72 from 80 and we're left with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 12

Moving on to step 5:
12 can be fit into 85 7 times, resulting in a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 867.0
The remainder is 1 after subtracting 84 from 85.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 12

Moving on to step 6:
18 divided by 12 is 1 with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 8671.0
The remainder is 6 after subtracting 12 from 18.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 12

On to step 7:
62 divided by 12 is 5 with a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 86715.0
If we take 60 away from 62, we end up with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 12

Going ahead to step 8:
If we divide 23 by 12, we get 1 and a remainder of 11.
The next digit of our result is 1. 
Result so far: 867151.0
If we take 12 away from 23, we end up 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.

Moving on to step 9:
When dividing 110 by 12, we get 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 867151.9
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.

Let's proceed to step 10:
12 can be fit into 20 1 times, resulting in a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 867151.91
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.

Going ahead to step 11:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 867151.916
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
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: 867151.9166
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.

After the division, we end up with 867151.9166 and a remainder of 8e-05.
