66762149 ÷ 12 
We want to divide 66762149 by 12.

Going ahead to step 1:
12 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 12

On to step 2:
12 can be fit into 66 5 times, resulting in a remainder of 6.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 60 from 66 and we're left with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 12

Step 3:
The number 12 fits into 67 5 times, leaving a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 55.0
The remainder is 7 after subtracting 60 from 67.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 12

Going ahead to step 4:
12 can be fit into 76 6 times, resulting in a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 556.0
Subtract 72 from 76 to get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 12

Step 5:
12 goes into 42 3 times with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 5563.0
Subtract 36 from 42 to get 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 12

Advancing to step 6:
61 divided by 12 is 5 with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 55635.0
The remainder is 1 after subtracting 60 from 61.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 12

On to step 7:
12 can be fit into 14 1 times, resulting in a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 556351.0
Subtracting 12 from 14 leaves us with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 12

Step 8:
29 divided by 12 is 2 with a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 5563512.0
Subtracting 24 from 29 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
50 divided by 12 is 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 5563512.4
Deduct 48 from 50 and we're left 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.

On to step 10:
12 can be fit into 20 1 times, resulting in a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 5563512.41
Deduct 12 from 20 and we're left 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.

Moving on to step 11:
12 goes into 80 6 times with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 5563512.416
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.

On to step 12:
80 divided by 12 is 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 5563512.4166
If we take 72 away from 80, we end up 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.

After the division, we end up with 5563512.4166 and a remainder of 8e-05.
