We look at the division of 171559 by 12 
We want to divide 171559 by 12.

Let's proceed to step 1:
12 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 12

Let's proceed to step 2:
12 goes into 17 1 times with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 12 from 17 and we're left with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 12

Let's proceed to step 3:
12 can be fit into 51 4 times, resulting in a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we subtract 48 from 51, we get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 12

Step 4:
If we divide 35 by 12, we get 2 and a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 142.0
If we take 24 away from 35, we end up with 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 12

Going ahead to step 5:
If we divide 115 by 12, we get 9 and a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 1429.0
The remainder is 7 after subtracting 108 from 115.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 12

Advancing to step 6:
When dividing 79 by 12, we get 6 with a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 14296.0
If we subtract 72 from 79, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
12 goes into 70 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 14296.5
The remainder is 10 after subtracting 60 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
12 goes into 100 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 14296.58
If we subtract 96 from 100, 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.

Moving on to step 9:
40 divided by 12 is 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 14296.583
Subtracting 36 from 40 leaves us 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.

Going ahead to step 10:
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: 14296.5833
Subtracting 36 from 40 leaves us 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.

The final outcome is 14296.5833, with a leftover of 4e-05.
