549637 ÷ 12 
We're looking to find how many times 12 goes into 549637.

Moving on to step 1:
12 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 12

Going ahead to step 2:
If we divide 54 by 12, we get 4 and a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 48 from 54 leaves us with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 12

Let's proceed to step 3:
69 divided by 12 is 5 with a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 45.0
The remainder is 9 after subtracting 60 from 69.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 12

Let's proceed to step 4:
96 divided by 12 is 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 458.0
If we take 96 away from 96, we end up with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 12

Moving on to step 5:
The number 12 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 4580.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 12

Step 6:
The number 12 fits into 37 3 times, leaving a remainder of 1.
The next digit of our result is 3. 
Result so far: 45803.0
If we subtract 36 from 37, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
When dividing 10 by 12, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 45803.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
12 goes into 100 8 times with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 45803.08
Subtract 96 from 100 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.

On to step 9:
12 goes into 40 3 times with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 45803.083
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
When dividing 40 by 12, we get 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 45803.0833
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 45803.0833, with a leftover of 4e-05.
