634959 ÷ 13 
The aim is to understand the frequency of 13 in 634959.

Step 1:
13 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 13

Going ahead to step 2:
13 goes into 63 4 times with a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 52 from 63 to get 11.
Append the next digit (4) from the dividend to 11 and continue with: 114 / 13

Let's proceed to step 3:
When dividing 114 by 13, we get 8 with a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 48.0
Subtracting 104 from 114 leaves us with 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 13

On to step 4:
109 divided by 13 is 8 with a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 488.0
The remainder is 5 after subtracting 104 from 109.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 13

Advancing to step 5:
When dividing 55 by 13, we get 4 with a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 4884.0
If we subtract 52 from 55, we get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 13

Advancing to step 6:
When dividing 39 by 13, we get 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 48843.0
If we subtract 39 from 39, 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.

On to step 7:
When dividing 0 by 13, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 48843.0
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.

Advancing to step 8:
The number 13 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 48843.0
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 quotient of the division is 48843.0, and the remainder is 0.0.
