We divide 12806355 by 129
The aim is to understand the frequency of 129 in 12806355.

Advancing to step 1:
129 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 129

Step 2:
The number 129 fits into 12 0 times, leaving a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 129

Advancing to step 3:
129 can be fit into 128 0 times, resulting in a remainder of 128.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 128, we get 128.
Bring next digit (0) of the dividend behind the 128 and repeat the process: 1280 / 129

Advancing to step 4:
The number 129 fits into 1280 9 times, leaving a remainder of 119.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 1161 from 1280 to get 119.
Fetch the next digit (6) from the dividend, attach it to 119 and continue: 1196 / 129

Moving on to step 5:
129 goes into 1196 9 times with a remainder of 35.
The next digit of our result is 9. 
Result so far: 99.0
Deduct 1161 from 1196 and we're left with 35.
Fetch the next digit (3) from the dividend, attach it to 35 and continue: 353 / 129

Going ahead to step 6:
353 divided by 129 is 2 with a remainder of 95.
Write down 2 as next digit of the result. 
Result so far: 992.0
Deduct 258 from 353 and we're left with 95.
Take the next digit (5) from the dividend and append it to 95, then repeat: 955 / 129

Step 7:
The number 129 fits into 955 7 times, leaving a remainder of 52.
Write down 7 as next digit of the result. 
Result so far: 9927.0
Deduct 903 from 955 and we're left with 52.
Bring next digit (5) of the dividend behind the 52 and repeat the process: 525 / 129

Going ahead to step 8:
525 divided by 129 is 4 with a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 99274.0
If we subtract 516 from 525, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 9:
129 goes into 90 0 times with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 99274.0
If we subtract 0 from 90, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 10:
If we divide 900 by 129, we get 6 and a remainder of 126.
The next digit of our result is 6. 
Result so far: 99274.06
Deduct 774 from 900 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Moving on to step 11:
The number 129 fits into 1260 9 times, leaving a remainder of 99.
The number 9 becomes the next digit in our result. 
Result so far: 99274.069
If we take 1161 away from 1260, we end up with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Going ahead to step 12:
129 goes into 990 7 times with a remainder of 87.
The next digit of our result is 7. 
Result so far: 99274.0697
The remainder is 87 after subtracting 903 from 990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 13:
870 divided by 129 is 6 with a remainder of 96.
Record the quotient 6 as the next digit in the result. 
Result so far: 99274.06976
Subtracting 774 from 870 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 14:
The number 129 fits into 960 7 times, leaving a remainder of 57.
Write down 7 as next digit of the result. 
Result so far: 99274.069767
Subtract 903 from 960 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 15:
129 goes into 570 4 times with a remainder of 54.
Put 4 as the next digit of the answer. 
Result so far: 99274.0697674
Subtracting 516 from 570 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 16:
When dividing 540 by 129, we get 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 99274.06976744
Deduct 516 from 540 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 99274.06976744 and a remainder of 2.4e-08.
