We divide 159185 by 12
Our goal is to divide 159185 by 12.

Let's proceed to step 1:
The number 12 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 12

Going ahead to step 2:
If we divide 15 by 12, we get 1 and a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 12 from 15, we get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 12

Going ahead to step 3:
12 can be fit into 39 3 times, resulting in a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 36 from 39 leaves us with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 12

On to step 4:
12 can be fit into 31 2 times, resulting in a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 132.0
Subtracting 24 from 31 leaves us with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 12

Step 5:
12 can be fit into 78 6 times, resulting in a remainder of 6.
The next digit of our result is 6. 
Result so far: 1326.0
The remainder is 6 after subtracting 72 from 78.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 12

Advancing to step 6:
The number 12 fits into 65 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 13265.0
The remainder is 5 after subtracting 60 from 65.
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:
50 divided by 12 is 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 13265.4
If we subtract 48 from 50, we get 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:
The number 12 fits into 20 1 times, leaving a remainder of 8.
The next digit of our result is 1. 
Result so far: 13265.41
Deduct 12 from 20 and we're left 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.

Step 9:
The number 12 fits into 80 6 times, leaving a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 13265.416
Subtract 72 from 80 to 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.

Step 10:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 13265.4166
Subtract 72 from 80 to 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.

In conclusion, the division gives 13265.4166 with a balance of 8e-05.
