12201276 divided by 18 
We're looking to find how many times 18 goes into 12201276.

Going ahead to step 1:
18 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 18

Going ahead to step 2:
The number 18 fits into 12 0 times, leaving a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 18

Advancing to step 3:
The number 18 fits into 122 6 times, leaving a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 108 from 122 leaves us with 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 18

Advancing to step 4:
If we divide 140 by 18, we get 7 and a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 67.0
Subtract 126 from 140 to get 14.
Include the next digit (1) from the dividend after 14, then repeat: 141 / 18

Let's proceed to step 5:
When dividing 141 by 18, we get 7 with a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 677.0
If we take 126 away from 141, we end up with 15.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 18

On to step 6:
152 divided by 18 is 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 6778.0
Subtract 144 from 152 to get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 18

Let's proceed to step 7:
18 goes into 87 4 times with a remainder of 15.
Write down 4 as next digit of the result. 
Result so far: 67784.0
Subtracting 72 from 87 leaves us with 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 18

On to step 8:
If we divide 156 by 18, we get 8 and a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 677848.0
The remainder is 12 after subtracting 144 from 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
120 divided by 18 is 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 677848.6
The remainder is 12 after subtracting 108 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
The number 18 fits into 120 6 times, leaving a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 677848.66
Deduct 108 from 120 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 677848.66, with a leftover of 0.012.
