63657949 divided by 12 
We want to divide 63657949 by 12.

Advancing to step 1:
The number 12 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 12

On to step 2:
When dividing 63 by 12, we get 5 with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 60 from 63 and we're left with 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 12

On to step 3:
12 can be fit into 36 3 times, resulting in a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
Subtract 36 from 36 to get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 12

Let's proceed to step 4:
12 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 530.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 12

Advancing to step 5:
12 can be fit into 57 4 times, resulting in a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 5304.0
The remainder is 9 after subtracting 48 from 57.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 12

Step 6:
12 can be fit into 99 8 times, resulting in a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 53048.0
The remainder is 3 after subtracting 96 from 99.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 12

Step 7:
12 goes into 34 2 times with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 530482.0
Deduct 24 from 34 and we're left with 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 12

Step 8:
12 can be fit into 109 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 5304829.0
The remainder is 1 after subtracting 108 from 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 9:
If we divide 10 by 12, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 5304829.0
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.

Advancing to step 10:
If we divide 100 by 12, we get 8 and a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 5304829.08
Subtracting 96 from 100 leaves us 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.

Advancing to step 11:
When dividing 40 by 12, we get 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 5304829.083
If we subtract 36 from 40, we 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 12:
When dividing 40 by 12, we get 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 5304829.0833
Subtract 36 from 40 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.

After the division, we end up with 5304829.0833 and a remainder of 4e-05.
