Let's divide 13016806 by 455
The aim is to understand the frequency of 455 in 13016806.

On to step 1:
1 divided by 455 is 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.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 455

Let's proceed to step 2:
455 goes into 13 0 times with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 455

On to step 3:
When dividing 130 by 455, we get 0 with a remainder of 130.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 130 and we're left with 130.
Bring next digit (1) of the dividend behind the 130 and repeat the process: 1301 / 455

Moving on to step 4:
When dividing 1301 by 455, we get 2 with a remainder of 391.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 910 from 1301, we get 391.
Include the next digit (6) from the dividend after 391, then repeat: 3916 / 455

Advancing to step 5:
If we divide 3916 by 455, we get 8 and a remainder of 276.
Put 8 as the next digit of the answer. 
Result so far: 28.0
Subtract 3640 from 3916 to get 276.
Include the next digit (8) from the dividend after 276, then repeat: 2768 / 455

On to step 6:
455 can be fit into 2768 6 times, resulting in a remainder of 38.
Record the quotient 6 as the next digit in the result. 
Result so far: 286.0
Subtract 2730 from 2768 to get 38.
Fetch the next digit (0) from the dividend, attach it to 38 and continue: 380 / 455

Advancing to step 7:
455 goes into 380 0 times with a remainder of 380.
The number 0 becomes the next digit in our result. 
Result so far: 2860.0
If we take 0 away from 380, we end up with 380.
Bring next digit (6) of the dividend behind the 380 and repeat the process: 3806 / 455

Moving on to step 8:
3806 divided by 455 is 8 with a remainder of 166.
Put 8 as the next digit of the answer. 
Result so far: 28608.0
Subtracting 3640 from 3806 leaves us with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Step 9:
455 can be fit into 1660 3 times, resulting in a remainder of 295.
Write down 3 as next digit of the result. 
Result so far: 28608.3
Subtract 1365 from 1660 to get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Step 10:
If we divide 2950 by 455, we get 6 and a remainder of 220.
Record the quotient 6 as the next digit in the result. 
Result so far: 28608.36
If we take 2730 away from 2950, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 11:
The number 455 fits into 2200 4 times, leaving a remainder of 380.
The next digit of our result is 4. 
Result so far: 28608.364
Deduct 1820 from 2200 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 12:
The number 455 fits into 3800 8 times, leaving a remainder of 160.
Record the quotient 8 as the next digit in the result. 
Result so far: 28608.3648
Deduct 3640 from 3800 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 13:
1600 divided by 455 is 3 with a remainder of 235.
Record the quotient 3 as the next digit in the result. 
Result so far: 28608.36483
Subtracting 1365 from 1600 leaves us with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

On to step 14:
455 goes into 2350 5 times with a remainder of 75.
The next digit of our result is 5. 
Result so far: 28608.364835
Subtract 2275 from 2350 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 15:
455 goes into 750 1 times with a remainder of 295.
Put 1 as the next digit of the answer. 
Result so far: 28608.3648351
Deduct 455 from 750 and we're left with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Moving on to step 16:
The number 455 fits into 2950 6 times, leaving a remainder of 220.
Put 6 as the next digit of the answer. 
Result so far: 28608.36483516
If we subtract 2730 from 2950, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

The final outcome is 28608.36483516, with a leftover of 2.2e-07.
