159593 divided by 12 
Let's see how many times 12 fits into 159593.

Moving 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
Subtract 0 from 1 to get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 12

Step 2:
The number 12 fits into 15 1 times, leaving a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 12 from 15 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 12

Going ahead to step 3:
When dividing 39 by 12, we get 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 36 from 39, we get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 12

On to step 4:
12 can be fit into 35 2 times, resulting in a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 132.0
The remainder is 11 after subtracting 24 from 35.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 12

Step 5:
119 divided by 12 is 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 1329.0
The remainder is 11 after subtracting 108 from 119.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 12

Step 6:
113 divided by 12 is 9 with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 13299.0
If we subtract 108 from 113, 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.

Let's proceed to step 7:
If we divide 50 by 12, we get 4 and a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 13299.4
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.

Moving on to step 8:
When dividing 20 by 12, we get 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 13299.41
If we take 12 away from 20, 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:
If we divide 80 by 12, we get 6 and a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 13299.416
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.

Let's proceed to step 10:
If we divide 80 by 12, we get 6 and a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 13299.4166
If we subtract 72 from 80, we 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.

Our division results in 13299.4166 with a remaining 8e-05.
