Let's divide 45114216 by 12
Let's see how many times 12 fits into 45114216.

On 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
Deduct 0 from 4 and we're left with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 12

Going ahead to step 2:
If we divide 45 by 12, we get 3 and 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.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 12

Advancing to step 3:
12 goes into 91 7 times with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 37.0
Deduct 84 from 91 and we're left with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 12

Advancing to step 4:
The number 12 fits into 71 5 times, leaving a remainder of 11.
The next digit of our result is 5. 
Result so far: 375.0
Deduct 60 from 71 and we're left with 11.
Fetch the next digit (4) from the dividend, attach it to 11 and continue: 114 / 12

Moving on to step 5:
12 goes into 114 9 times with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 3759.0
Subtracting 108 from 114 leaves us with 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 12

Moving on to step 6:
If we divide 62 by 12, we get 5 and a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 37595.0
If we subtract 60 from 62, we get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 12

On to step 7:
If we divide 21 by 12, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 375951.0
If we subtract 12 from 21, we get 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 12

On to step 8:
If we divide 96 by 12, we get 8 and a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 3759518.0
Deduct 96 from 96 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.

Let's proceed 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: 3759518.0
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.

Moving on to step 10:
12 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3759518.0
Deduct 0 from 0 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.

Our division results in 3759518.0 with a remaining 0.0.
