Let's divide 454900 by 12
Our goal is to divide 454900 by 12.

Going ahead to step 1:
12 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 12

Advancing to step 2:
When dividing 45 by 12, we get 3 with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 36 from 45 to get 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 12

Advancing to step 3:
The number 12 fits into 94 7 times, leaving a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 37.0
The remainder is 10 after subtracting 84 from 94.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 12

Advancing to step 4:
12 goes into 109 9 times with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 379.0
If we subtract 108 from 109, we get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 12

Advancing to step 5:
If we divide 10 by 12, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 3790.0
If we take 0 away from 10, we end up with 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 12

Moving on to step 6:
12 goes into 100 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 37908.0
The remainder is 4 after subtracting 96 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
When dividing 40 by 12, we get 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 37908.3
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 37908.33
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 37908.33 and a remainder of 0.004.
