We're dividing 620984 by 13 
The aim is to understand the frequency of 13 in 620984.

Moving on to 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
The remainder is 6 after subtracting 0 from 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 13

Advancing to step 2:
13 goes into 62 4 times with a remainder of 10.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 52 from 62 leaves us with 10.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 13

Going ahead to step 3:
If we divide 100 by 13, we get 7 and a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
Deduct 91 from 100 and we're left with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 13

Let's proceed to step 4:
When dividing 99 by 13, we get 7 with a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 477.0
If we take 91 away from 99, we end up with 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 13

On to step 5:
When dividing 88 by 13, we get 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 4776.0
Subtract 78 from 88 to get 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 13

Going ahead to step 6:
The number 13 fits into 104 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 47768.0
Subtract 104 from 104 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.

Let's proceed to step 7:
If we divide 0 by 13, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 47768.0
If we take 0 away from 0, 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 8:
If we divide 0 by 13, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 47768.0
If we take 0 away from 0, 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.

In conclusion, the division gives 47768.0 with a balance of 0.0.
