456855 divided by 12 
We want to figure out the number of times 456855 can be divided by 12.

Advancing to step 1:
When dividing 4 by 12, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 12

On to step 2:
45 divided by 12 is 3 with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 36 from 45 to get 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 12

On to step 3:
The number 12 fits into 96 8 times, leaving a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 38.0
Subtract 96 from 96 to get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 12

Going ahead to step 4:
When dividing 8 by 12, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 380.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 12

Going ahead to step 5:
If we divide 85 by 12, we get 7 and a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 3807.0
Subtracting 84 from 85 leaves us with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 12

Moving on to step 6:
12 goes into 15 1 times with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 38071.0
The remainder is 3 after subtracting 12 from 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
The number 12 fits into 30 2 times, leaving a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 38071.2
If we take 24 away from 30, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
If we divide 60 by 12, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 38071.25
Deduct 60 from 60 and we're left 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.

Advancing to step 9:
When dividing 0 by 12, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 38071.25
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
0 divided by 12 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 38071.25
Subtracting 0 from 0 leaves us 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 final result is 38071.25 with a remainder of 0.0.
