We look at the division of 160790 by 12 
We want to figure out the number of times 160790 can be divided by 12.

Advancing to step 1:
12 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 12

Going ahead to step 2:
The number 12 fits into 16 1 times, leaving a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 12 from 16 leaves us with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 12

On to step 3:
When dividing 40 by 12, we get 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 13.0
The remainder is 4 after subtracting 36 from 40.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 12

On to step 4:
12 can be fit into 47 3 times, resulting in a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 133.0
If we subtract 36 from 47, we get 11.
Include the next digit (9) from the dividend after 11, then repeat: 119 / 12

Let's proceed to step 5:
12 can be fit into 119 9 times, resulting in a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 1339.0
If we take 108 away from 119, we end up with 11.
Bring next digit (0) of the dividend behind the 11 and repeat the process: 110 / 12

On to step 6:
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: 13399.0
Deduct 108 from 110 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.

Going ahead to step 7:
If we divide 20 by 12, we get 1 and a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 13399.1
The remainder is 8 after subtracting 12 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
When dividing 80 by 12, we get 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 13399.16
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.

Moving on to step 9:
80 divided by 12 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 13399.166
Subtracting 72 from 80 leaves us 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.

The final result is 13399.166 with a remainder of 0.0008.
