12665278 ÷ 907 
The aim is to understand the frequency of 907 in 12665278.

Going ahead to step 1:
If we divide 1 by 907, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 907

Let's proceed to step 2:
When dividing 12 by 907, we get 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Include the next digit (6) from the dividend after 12, then repeat: 126 / 907

Let's proceed to step 3:
126 divided by 907 is 0 with a remainder of 126.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 126 to get 126.
Bring next digit (6) of the dividend behind the 126 and repeat the process: 1266 / 907

Moving on to step 4:
If we divide 1266 by 907, we get 1 and a remainder of 359.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 907 from 1266 to get 359.
Append the next digit (5) from the dividend to 359 and continue with: 3595 / 907

On to step 5:
When dividing 3595 by 907, we get 3 with a remainder of 874.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 2721 from 3595 leaves us with 874.
Bring next digit (2) of the dividend behind the 874 and repeat the process: 8742 / 907

On to step 6:
The number 907 fits into 8742 9 times, leaving a remainder of 579.
Use 9 as the next digit of our solution. 
Result so far: 139.0
Subtract 8163 from 8742 to get 579.
Bring next digit (7) of the dividend behind the 579 and repeat the process: 5797 / 907

Step 7:
907 can be fit into 5797 6 times, resulting in a remainder of 355.
Record the quotient 6 as the next digit in the result. 
Result so far: 1396.0
Subtracting 5442 from 5797 leaves us with 355.
Append the next digit (8) from the dividend to 355 and continue with: 3558 / 907

On to step 8:
907 goes into 3558 3 times with a remainder of 837.
Write down 3 as next digit of the result. 
Result so far: 13963.0
The remainder is 837 after subtracting 2721 from 3558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8370, and continue the process.

Going ahead to step 9:
907 goes into 8370 9 times with a remainder of 207.
Record the quotient 9 as the next digit in the result. 
Result so far: 13963.9
If we subtract 8163 from 8370, we get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Moving on to step 10:
907 can be fit into 2070 2 times, resulting in a remainder of 256.
Write down 2 as next digit of the result. 
Result so far: 13963.92
If we take 1814 away from 2070, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 11:
If we divide 2560 by 907, we get 2 and a remainder of 746.
Record the quotient 2 as the next digit in the result. 
Result so far: 13963.922
Subtract 1814 from 2560 to get 746.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7460, and continue the process.

The final result is 13963.922 with a remainder of 0.0746.
