454204 divided by 12 
We want to divide 454204 by 12.

Step 1:
12 goes into 4 0 times 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.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 12

Advancing to step 2:
45 divided by 12 is 3 with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 36 from 45 leaves us with 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 12

On to step 3:
The number 12 fits into 94 7 times, leaving a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
Subtract 84 from 94 to get 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 12

Going ahead to step 4:
When dividing 102 by 12, we get 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 378.0
Deduct 96 from 102 and we're left with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 12

On to step 5:
When dividing 60 by 12, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 3785.0
The remainder is 0 after subtracting 60 from 60.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 12

Going ahead to step 6:
If we divide 4 by 12, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 37850.0
Deduct 0 from 4 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
If we divide 40 by 12, we get 3 and a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 37850.3
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 37850.33
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 37850.33 with a remaining 0.004.
