407372 ÷ 12 
We're looking to find how many times 12 goes into 407372.

Going ahead to step 1:
The number 12 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 12

Advancing to step 2:
12 goes into 40 3 times with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 4 after subtracting 36 from 40.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 12

Step 3:
If we divide 47 by 12, we get 3 and a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Deduct 36 from 47 and we're left with 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 12

Advancing to step 4:
113 divided by 12 is 9 with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 339.0
If we take 108 away from 113, we end up with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 12

Going ahead to step 5:
If we divide 57 by 12, we get 4 and a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 3394.0
The remainder is 9 after subtracting 48 from 57.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 12

Advancing to step 6:
12 goes into 92 7 times with a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 33947.0
Subtracting 84 from 92 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
The number 12 fits into 80 6 times, leaving a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 33947.6
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
The number 12 fits into 80 6 times, leaving a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 33947.66
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 33947.66 and a remainder of 0.008.
