We're dividing 487212 by 12 
We're looking to find how many times 12 goes into 487212.

Advancing to 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
Deduct 0 from 4 and we're left with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 12

Going ahead to step 2:
48 divided by 12 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 48 from 48 and we're left with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 12

On to step 3:
12 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
If we subtract 0 from 7, we get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 12

Let's proceed to step 4:
When dividing 72 by 12, we get 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 406.0
Deduct 72 from 72 and we're left with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 12

Moving on to step 5:
When dividing 1 by 12, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 4060.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 12

Let's proceed to step 6:
12 divided by 12 is 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 40601.0
The remainder is 0 after subtracting 12 from 12.
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 7:
When dividing 0 by 12, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 40601.0
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.

On to step 8:
12 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 40601.0
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 40601.0, and the remainder is 0.0.
