We divide 259045 by 12
We want to divide 259045 by 12.

On to step 1:
The number 12 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 12

Let's proceed to step 2:
The number 12 fits into 25 2 times, leaving 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.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 12

Step 3:
If we divide 19 by 12, we get 1 and a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we take 12 away from 19, we end up with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 12

Moving on to step 4:
When dividing 70 by 12, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 215.0
Subtracting 60 from 70 leaves us with 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 12

On to step 5:
When dividing 104 by 12, we get 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 2158.0
Subtract 96 from 104 to get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 12

On to step 6:
85 divided by 12 is 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 21587.0
If we subtract 84 from 85, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
10 divided by 12 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 21587.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
The number 12 fits into 100 8 times, leaving a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 21587.08
If we take 96 away from 100, we end up 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.

Step 9:
When dividing 40 by 12, we get 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 21587.083
Subtract 36 from 40 to 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.

Step 10:
If we divide 40 by 12, we get 3 and a remainder of 4.
The next digit of our result is 3. 
Result so far: 21587.0833
If we subtract 36 from 40, 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.

Our division results in 21587.0833 with a remaining 4e-05.
