We look at the division of 12866660 by 912 
The aim is to understand the frequency of 912 in 12866660.

Advancing to step 1:
When dividing 1 by 912, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 912

Advancing to step 2:
When dividing 12 by 912, we get 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 912

Going ahead to step 3:
When dividing 128 by 912, we get 0 with a remainder of 128.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 128, we end up with 128.
Grab the next digit (6) from the dividend, add it to 128, then carry on: 1286 / 912

Step 4:
912 can be fit into 1286 1 times, resulting in a remainder of 374.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 912 from 1286, we get 374.
Fetch the next digit (6) from the dividend, attach it to 374 and continue: 3746 / 912

Going ahead to step 5:
912 can be fit into 3746 4 times, resulting in a remainder of 98.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtracting 3648 from 3746 leaves us with 98.
Include the next digit (6) from the dividend after 98, then repeat: 986 / 912

On to step 6:
912 goes into 986 1 times with a remainder of 74.
Record the quotient 1 as the next digit in the result. 
Result so far: 141.0
Deduct 912 from 986 and we're left with 74.
Append the next digit (6) from the dividend to 74 and continue with: 746 / 912

Let's proceed to step 7:
912 can be fit into 746 0 times, resulting in a remainder of 746.
The number 0 becomes the next digit in our result. 
Result so far: 1410.0
Subtract 0 from 746 to get 746.
Grab the next digit (0) from the dividend, add it to 746, then carry on: 7460 / 912

Step 8:
If we divide 7460 by 912, we get 8 and a remainder of 164.
Put 8 as the next digit of the answer. 
Result so far: 14108.0
Deduct 7296 from 7460 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 9:
The number 912 fits into 1640 1 times, leaving a remainder of 728.
Put 1 as the next digit of the answer. 
Result so far: 14108.1
Deduct 912 from 1640 and we're left with 728.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

Moving on to step 10:
912 goes into 7280 7 times with a remainder of 896.
The next digit of our result is 7. 
Result so far: 14108.17
Subtract 6384 from 7280 to get 896.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8960, and continue the process.

Moving on to step 11:
912 goes into 8960 9 times with a remainder of 752.
Record the quotient 9 as the next digit in the result. 
Result so far: 14108.179
The remainder is 752 after subtracting 8208 from 8960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

Let's proceed to step 12:
The number 912 fits into 7520 8 times, leaving a remainder of 224.
Put 8 as the next digit of the answer. 
Result so far: 14108.1798
Deduct 7296 from 7520 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 13:
912 can be fit into 2240 2 times, resulting in a remainder of 416.
The number 2 becomes the next digit in our result. 
Result so far: 14108.17982
If we subtract 1824 from 2240, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 14:
912 goes into 4160 4 times with a remainder of 512.
The next digit of our result is 4. 
Result so far: 14108.179824
If we take 3648 away from 4160, we end up with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Let's proceed to step 15:
912 can be fit into 5120 5 times, resulting in a remainder of 560.
Use 5 as the next digit of our solution. 
Result so far: 14108.1798245
The remainder is 560 after subtracting 4560 from 5120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 16:
912 goes into 5600 6 times with a remainder of 128.
Write down 6 as next digit of the result. 
Result so far: 14108.17982456
If we take 5472 away from 5600, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Our division results in 14108.17982456 with a remaining 1.28e-07.
