We look at the division of 162390 by 12 
We want to divide 162390 by 12.

Going ahead to step 1:
The number 12 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 12

On to step 2:
The number 12 fits into 16 1 times, leaving a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 12 from 16 leaves us with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 12

Moving on to step 3:
The number 12 fits into 42 3 times, leaving a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 6 after subtracting 36 from 42.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 12

Moving on to step 4:
If we divide 63 by 12, we get 5 and a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 135.0
Subtracting 60 from 63 leaves us with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 12

Step 5:
12 goes into 39 3 times with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 1353.0
If we take 36 away from 39, we end up with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 12

Step 6:
The number 12 fits into 30 2 times, leaving a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 13532.0
Subtract 24 from 30 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
60 divided by 12 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 13532.5
Deduct 60 from 60 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
0 divided by 12 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 13532.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 13532.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 13532.5 with a balance of 0.0.
