638547 ÷ 12 
Let's see how many times 12 fits into 638547.

Step 1:
If we divide 6 by 12, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 12

Going ahead to step 2:
When dividing 63 by 12, we get 5 with a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 60 away from 63, we end up with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 12

Moving on to step 3:
12 can be fit into 38 3 times, resulting in a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 53.0
Subtracting 36 from 38 leaves us with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 12

Going ahead to step 4:
25 divided by 12 is 2 with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 532.0
Subtract 24 from 25 to get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 12

Step 5:
12 can be fit into 14 1 times, resulting in a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 5321.0
Subtract 12 from 14 to get 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 12

Moving on to step 6:
12 goes into 27 2 times with a remainder of 3.
The next digit of our result is 2. 
Result so far: 53212.0
Subtract 24 from 27 to get 3.
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.
Record the quotient 2 as the next digit in the result. 
Result so far: 53212.2
Subtract 24 from 30 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
60 divided by 12 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 53212.25
The remainder is 0 after subtracting 60 from 60.
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 9:
12 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 53212.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
If we divide 0 by 12, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 53212.25
The remainder is 0 after subtracting 0 from 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 quotient of the division is 53212.25, and the remainder is 0.0.
