190870 divided by 12 
We want to divide 190870 by 12.

On to step 1:
1 divided by 12 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 12

Moving on to step 2:
If we divide 19 by 12, we get 1 and a remainder of 7.
Put 1 as the next digit of the answer. 
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

On to step 3:
The number 12 fits into 70 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtract 60 from 70 to get 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 12

On to step 4:
If we divide 108 by 12, we get 9 and a remainder of 0.
The next digit of our result is 9. 
Result so far: 159.0
Subtracting 108 from 108 leaves us with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 12

Let's proceed to step 5:
When dividing 7 by 12, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 1590.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 12

Advancing to step 6:
12 goes into 70 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 15905.0
Subtract 60 from 70 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
12 can be fit into 100 8 times, resulting in a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 15905.8
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.
The number 3 becomes the next digit in our result. 
Result so far: 15905.83
If we subtract 36 from 40, we 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.

Step 9:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 15905.833
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.

In conclusion, the division gives 15905.833 with a balance of 0.0004.
