1287797 divided by 12 
The aim is to understand the frequency of 12 in 1287797.

Moving on to step 1:
The number 12 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 12

Let's proceed to step 2:
The number 12 fits into 12 1 times, leaving a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 0 after subtracting 12 from 12.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 12

Going ahead to step 3:
If we divide 8 by 12, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 8 to get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 12

Advancing to step 4:
12 goes into 87 7 times with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 107.0
If we subtract 84 from 87, we get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 12

On to step 5:
If we divide 37 by 12, we get 3 and a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 1073.0
The remainder is 1 after subtracting 36 from 37.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 12

Step 6:
When dividing 19 by 12, we get 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 10731.0
If we subtract 12 from 19, we get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 12

Let's proceed to step 7:
The number 12 fits into 77 6 times, leaving a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 107316.0
If we take 72 away from 77, we end up 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.

Going ahead to step 8:
If we divide 50 by 12, we get 4 and a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 107316.4
Subtract 48 from 50 to get 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 9:
12 goes into 20 1 times with a remainder of 8.
The next digit of our result is 1. 
Result so far: 107316.41
If we subtract 12 from 20, we 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.

Moving on to step 10:
80 divided by 12 is 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 107316.416
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
The number 12 fits into 80 6 times, leaving a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 107316.4166
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.

In conclusion, the division gives 107316.4166 with a balance of 8e-05.
