431502 ÷ 12 
We want to divide 431502 by 12.

Going ahead to step 1:
When dividing 4 by 12, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 12

Step 2:
12 goes into 43 3 times with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 36 away from 43, we end up with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 12

Going ahead to step 3:
71 divided by 12 is 5 with a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
Subtracting 60 from 71 leaves us with 11.
Bring next digit (5) of the dividend behind the 11 and repeat the process: 115 / 12

Going ahead to step 4:
When dividing 115 by 12, we get 9 with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 359.0
The remainder is 7 after subtracting 108 from 115.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 12

Let's proceed to step 5:
If we divide 70 by 12, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 3595.0
Deduct 60 from 70 and we're left with 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 12

Moving on to step 6:
The number 12 fits into 102 8 times, leaving a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 35958.0
Subtract 96 from 102 to get 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 7:
60 divided by 12 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 35958.5
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.

Step 8:
12 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 35958.5
Subtract 0 from 0 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.

Advancing to step 9:
If we divide 0 by 12, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 35958.5
Subtract 0 from 0 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.

After the division, we end up with 35958.5 and a remainder of 0.0.
