49867630 ÷ 12 
Our goal is to divide 49867630 by 12.

Step 1:
4 divided by 12 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 12

Step 2:
If we divide 49 by 12, we get 4 and a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 1 after subtracting 48 from 49.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 12

Step 3:
The number 12 fits into 18 1 times, leaving a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
If we take 12 away from 18, we end up with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 12

Moving on to step 4:
The number 12 fits into 66 5 times, leaving a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 415.0
Subtract 60 from 66 to get 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 12

Let's proceed to step 5:
67 divided by 12 is 5 with a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 4155.0
The remainder is 7 after subtracting 60 from 67.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 12

Step 6:
If we divide 76 by 12, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 41556.0
If we take 72 away from 76, we end up with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 12

Advancing to step 7:
43 divided by 12 is 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 415563.0
If we take 36 away from 43, we end up with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 12

Going ahead to step 8:
12 can be fit into 70 5 times, resulting in a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 4155635.0
The remainder is 10 after subtracting 60 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
12 goes into 100 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 4155635.8
If we subtract 96 from 100, 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.

Step 10:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 4155635.83
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.

On to step 11:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 4155635.833
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 quotient of the division is 4155635.833, and the remainder is 0.0004.
