190570 divided by 12 
Let's see how many times 12 fits into 190570.

Going ahead to step 1:
12 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 12

Step 2:
If we divide 19 by 12, we get 1 and a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 12 from 19 and we're left with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 12

Let's proceed to step 3:
12 goes into 70 5 times with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 60 from 70 leaves us with 10.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 12

Let's proceed to step 4:
The number 12 fits into 105 8 times, leaving a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 158.0
If we subtract 96 from 105, we get 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 12

Let's proceed to step 5:
When dividing 97 by 12, we get 8 with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 1588.0
Deduct 96 from 97 and we're left with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 12

Moving on to step 6:
When dividing 10 by 12, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 15880.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
The number 12 fits into 100 8 times, leaving a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 15880.8
Subtract 96 from 100 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 15880.83
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
40 divided by 12 is 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 15880.833
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 15880.833 with a remaining 0.0004.
