Let's divide 619312 by 13
The aim is to understand the frequency of 13 in 619312.

Moving on to step 1:
6 divided by 13 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 13

Moving on to step 2:
13 can be fit into 61 4 times, resulting in a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 52 from 61 to get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 13

Step 3:
The number 13 fits into 99 7 times, leaving a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 47.0
If we subtract 91 from 99, we get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 13

Let's proceed to step 4:
If we divide 83 by 13, we get 6 and a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 476.0
Subtracting 78 from 83 leaves us with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 13

Step 5:
51 divided by 13 is 3 with a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 4763.0
If we take 39 away from 51, we end up with 12.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 13

Advancing to step 6:
13 goes into 122 9 times with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 47639.0
If we subtract 117 from 122, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
If we divide 50 by 13, we get 3 and a remainder of 11.
The next digit of our result is 3. 
Result so far: 47639.3
Subtract 39 from 50 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 8:
The number 13 fits into 110 8 times, leaving a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 47639.38
The remainder is 6 after subtracting 104 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
13 goes into 60 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 47639.384
If we take 52 away from 60, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
If we divide 80 by 13, we get 6 and a remainder of 2.
The next digit of our result is 6. 
Result so far: 47639.3846
If we subtract 78 from 80, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
13 can be fit into 20 1 times, resulting in a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 47639.38461
If we take 13 away from 20, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 12:
13 goes into 70 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 47639.384615
Subtracting 65 from 70 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 13:
When dividing 50 by 13, we get 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 47639.3846153
If we take 39 away from 50, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 14:
When dividing 110 by 13, we get 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 47639.38461538
Subtract 104 from 110 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 47639.38461538 and a remainder of 6e-09.
