We're dividing 338577 by 12 
We want to divide 338577 by 12.

Step 1:
The number 12 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 12

On to step 2:
If we divide 33 by 12, we get 2 and a remainder of 9.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 24 from 33 leaves us with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 12

Advancing to step 3:
12 goes into 98 8 times with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Deduct 96 from 98 and we're left with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 12

On to step 4:
When dividing 25 by 12, we get 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 282.0
Deduct 24 from 25 and we're left with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 12

Advancing to step 5:
If we divide 17 by 12, we get 1 and a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 2821.0
Subtract 12 from 17 to get 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 12

Let's proceed to step 6:
The number 12 fits into 57 4 times, leaving a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 28214.0
If we take 48 away from 57, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
The number 12 fits into 90 7 times, leaving a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 28214.7
If we take 84 away from 90, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
If we divide 60 by 12, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 28214.75
The remainder is 0 after subtracting 60 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 28214.75
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
0 divided by 12 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 28214.75
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 28214.75 and a remainder of 0.0.
