Let's divide 883143 by 13
The aim is to understand the frequency of 13 in 883143.

Moving on to step 1:
13 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 13

Moving on to step 2:
13 goes into 88 6 times with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 78 from 88 to get 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 13

Going ahead to step 3:
103 divided by 13 is 7 with a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 67.0
The remainder is 12 after subtracting 91 from 103.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 13

Going ahead to step 4:
The number 13 fits into 121 9 times, leaving a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 679.0
Deduct 117 from 121 and we're left with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 13

Step 5:
44 divided by 13 is 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 6793.0
Subtract 39 from 44 to get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 13

On to step 6:
The number 13 fits into 53 4 times, leaving a remainder of 1.
The next digit of our result is 4. 
Result so far: 67934.0
Subtracting 52 from 53 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
13 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 67934.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
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: 67934.07
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.

Step 9:
If we divide 90 by 13, we get 6 and a remainder of 12.
The next digit of our result is 6. 
Result so far: 67934.076
If we take 78 away from 90, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
If we divide 120 by 13, we get 9 and a remainder of 3.
The next digit of our result is 9. 
Result so far: 67934.0769
Subtracting 117 from 120 leaves us 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.

Going ahead to step 11:
13 can be fit into 30 2 times, resulting in a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 67934.07692
If we subtract 26 from 30, we 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.

Step 12:
13 goes into 40 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 67934.076923
The remainder is 1 after subtracting 39 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 13:
13 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 67934.076923
Subtract 0 from 10 to get 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 14:
The number 13 fits into 100 7 times, leaving a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 67934.07692307
The remainder is 9 after subtracting 91 from 100.
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 67934.07692307, and the remainder is 9e-09.
