545546 divided by 12 
We're looking to find how many times 12 goes into 545546.

Step 1:
5 divided by 12 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 12

Going ahead to step 2:
If we divide 54 by 12, we get 4 and a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 48 from 54 leaves us with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 12

On to step 3:
The number 12 fits into 65 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
Subtract 60 from 65 to get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 12

Moving on to step 4:
12 can be fit into 55 4 times, resulting in a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 454.0
If we take 48 away from 55, we end up with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 12

Step 5:
When dividing 74 by 12, we get 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 4546.0
Subtract 72 from 74 to get 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 12

Moving on to step 6:
26 divided by 12 is 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 45462.0
Subtracting 24 from 26 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
If we divide 20 by 12, we get 1 and a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 45462.1
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.

Going ahead to step 8:
12 can be fit into 80 6 times, resulting in a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 45462.16
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:
12 goes into 80 6 times with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 45462.166
Subtracting 72 from 80 leaves us with 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 quotient of the division is 45462.166, and the remainder is 0.0008.
