343566 divided by 12 
Our goal is to divide 343566 by 12.

Moving on to step 1:
When dividing 3 by 12, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 12

On to step 2:
When dividing 34 by 12, we get 2 with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 24 from 34, we get 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 12

Step 3:
12 goes into 103 8 times with a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 28.0
If we take 96 away from 103, we end up with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 12

Advancing to step 4:
When dividing 75 by 12, we get 6 with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 286.0
Subtracting 72 from 75 leaves us with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 12

Advancing to step 5:
36 divided by 12 is 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 2863.0
If we take 36 away from 36, we end up with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 12

Moving on to step 6:
12 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 28630.0
Deduct 0 from 6 and we're left 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.

Moving on to step 7:
12 goes into 60 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 28630.5
Subtract 60 from 60 to 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.

Moving on to step 8:
The number 12 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 28630.5
Subtracting 0 from 0 leaves us 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.

Step 9:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 28630.5
If we take 0 away from 0, we end up 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.

The quotient of the division is 28630.5, and the remainder is 0.0.
