908505 divided by 13 
The aim is to understand the frequency of 13 in 908505.

Moving on to step 1:
13 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 13

On to step 2:
90 divided by 13 is 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 12 after subtracting 78 from 90.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 13

Let's proceed to step 3:
If we divide 128 by 13, we get 9 and a remainder of 11.
The next digit of our result is 9. 
Result so far: 69.0
The remainder is 11 after subtracting 117 from 128.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 13

Advancing to step 4:
The number 13 fits into 115 8 times, leaving a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 698.0
Subtract 104 from 115 to get 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 13

Going ahead to step 5:
If we divide 110 by 13, we get 8 and a remainder of 6.
The next digit of our result is 8. 
Result so far: 6988.0
If we subtract 104 from 110, we get 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 13

On to step 6:
If we divide 65 by 13, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 69885.0
If we take 65 away from 65, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
The number 13 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 69885.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
13 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 69885.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 69885.0 with a remainder of 0.0.
