We divide 255353 by 12
We want to divide 255353 by 12.

Advancing to step 1:
If we divide 2 by 12, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 12

Advancing to step 2:
When dividing 25 by 12, we get 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 24 from 25 and we're left with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 12

Step 3:
If we divide 15 by 12, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 21.0
Subtracting 12 from 15 leaves us with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 12

Going ahead to step 4:
12 goes into 33 2 times with a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 212.0
Subtract 24 from 33 to get 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 12

Let's proceed to step 5:
12 can be fit into 95 7 times, resulting in a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 2127.0
If we subtract 84 from 95, we get 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 12

Step 6:
The number 12 fits into 113 9 times, leaving a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 21279.0
The remainder is 5 after subtracting 108 from 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
12 goes into 50 4 times with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 21279.4
The remainder is 2 after subtracting 48 from 50.
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 8:
12 can be fit into 20 1 times, resulting in a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 21279.41
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.

Advancing to step 9:
12 goes into 80 6 times with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 21279.416
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.

Let's proceed to step 10:
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: 21279.4166
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.

The final outcome is 21279.4166, with a leftover of 8e-05.
