We're dividing 469599 by 12 
We're looking to find how many times 12 goes into 469599.

Step 1:
The number 12 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 12

On to step 2:
12 goes into 46 3 times with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 10 after subtracting 36 from 46.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 12

On to step 3:
12 can be fit into 109 9 times, resulting in a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
Deduct 108 from 109 and we're left with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 12

Let's proceed to step 4:
15 divided by 12 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 391.0
If we take 12 away from 15, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 12

Moving on to step 5:
If we divide 39 by 12, we get 3 and a remainder of 3.
The next digit of our result is 3. 
Result so far: 3913.0
If we subtract 36 from 39, we get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 12

Moving on to step 6:
39 divided by 12 is 3 with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 39133.0
Subtract 36 from 39 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
When dividing 30 by 12, we get 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 39133.2
Deduct 24 from 30 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.

Going ahead to step 8:
When dividing 60 by 12, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 39133.25
Deduct 60 from 60 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 9:
If we divide 0 by 12, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 39133.25
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.

On to step 10:
12 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 39133.25
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.

Our division results in 39133.25 with a remaining 0.0.
