Let's divide 455174 by 12
Our goal is to divide 455174 by 12.

Going ahead to step 1:
If we divide 4 by 12, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 12

Moving on to step 2:
12 can be fit into 45 3 times, resulting in a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 36 from 45 and we're left with 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 12

Advancing to step 3:
If we divide 95 by 12, we get 7 and a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 37.0
Deduct 84 from 95 and we're left with 11.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 12

Step 4:
111 divided by 12 is 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 379.0
Deduct 108 from 111 and we're left with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 12

On to step 5:
When dividing 37 by 12, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 3793.0
If we subtract 36 from 37, we get 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 12

Going ahead to step 6:
12 can be fit into 14 1 times, resulting in a remainder of 2.
The next digit of our result is 1. 
Result so far: 37931.0
If we subtract 12 from 14, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
When dividing 20 by 12, we get 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 37931.1
If we subtract 12 from 20, we get 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:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 37931.16
Subtract 72 from 80 to get 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 9:
When dividing 80 by 12, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 37931.166
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 37931.166 with a remainder of 0.0008.
