875018 divided by 13 
The aim is to understand the frequency of 13 in 875018.

Step 1:
When dividing 8 by 13, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 13

Going ahead to step 2:
13 can be fit into 87 6 times, resulting in a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 78 from 87 and we're left with 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 13

Step 3:
13 goes into 95 7 times with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 67.0
Subtracting 91 from 95 leaves us with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 13

Step 4:
The number 13 fits into 40 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 673.0
Subtract 39 from 40 to get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 13

Going ahead to step 5:
When dividing 11 by 13, we get 0 with a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 6730.0
Subtracting 0 from 11 leaves us with 11.
Take the next digit (8) from the dividend and append it to 11, then repeat: 118 / 13

Step 6:
118 divided by 13 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 67309.0
The remainder is 1 after subtracting 117 from 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
13 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 67309.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
The number 13 fits into 100 7 times, leaving a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 67309.07
Subtract 91 from 100 to 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.

Let's proceed to step 9:
The number 13 fits into 90 6 times, leaving a remainder of 12.
The next digit of our result is 6. 
Result so far: 67309.076
The remainder is 12 after subtracting 78 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
The number 13 fits into 120 9 times, leaving a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 67309.0769
If we take 117 away from 120, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 11:
When dividing 30 by 13, we get 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 67309.07692
Subtract 26 from 30 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 12:
13 can be fit into 40 3 times, resulting in a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 67309.076923
Subtract 39 from 40 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 13:
13 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 67309.076923
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 14:
The number 13 fits into 100 7 times, leaving a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 67309.07692307
Subtracting 91 from 100 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The quotient of the division is 67309.07692307, and the remainder is 9e-09.
