190805 ÷ 12 
Let's see how many times 12 fits into 190805.

Step 1:
When dividing 1 by 12, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 12

Advancing to step 2:
12 can be fit into 19 1 times, resulting in a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 7 after subtracting 12 from 19.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 12

Moving on to step 3:
When dividing 70 by 12, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtracting 60 from 70 leaves us with 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 12

On to step 4:
If we divide 108 by 12, we get 9 and a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 159.0
Subtracting 108 from 108 leaves us with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 12

Advancing to step 5:
If we divide 0 by 12, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1590.0
If we subtract 0 from 0, we get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 12

Going ahead to step 6:
If we divide 5 by 12, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 15900.0
If we subtract 0 from 5, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
12 goes into 50 4 times with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 15900.4
Deduct 48 from 50 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.

On to step 8:
When dividing 20 by 12, we get 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 15900.41
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.

Step 9:
12 goes into 80 6 times with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 15900.416
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.

Going ahead to step 10:
80 divided by 12 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 15900.4166
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.

Our division results in 15900.4166 with a remaining 8e-05.
