We divide 245879 by 12
Let's see how many times 12 fits into 245879.

Going ahead to step 1:
If we divide 2 by 12, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 12

On to step 2:
24 divided by 12 is 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 24 away from 24, we end up with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 12

Step 3:
12 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtract 0 from 5 to get 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 12

Let's proceed to step 4:
58 divided by 12 is 4 with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 204.0
If we take 48 away from 58, we end up with 10.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 12

On to step 5:
When dividing 107 by 12, we get 8 with a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 2048.0
Subtracting 96 from 107 leaves us with 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 12

On to step 6:
12 can be fit into 119 9 times, resulting in a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 20489.0
If we subtract 108 from 119, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
12 can be fit into 110 9 times, resulting in a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 20489.9
The remainder is 2 after subtracting 108 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

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: 20489.91
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.

Going ahead to step 9:
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: 20489.916
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.

Step 10:
80 divided by 12 is 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 20489.9166
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.

After the division, we end up with 20489.9166 and a remainder of 8e-05.
