716321 ÷ 13 
The aim is to understand the frequency of 13 in 716321.

Advancing to step 1:
When dividing 7 by 13, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 13

Let's proceed to step 2:
71 divided by 13 is 5 with a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 65 from 71 leaves us with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 13

On to step 3:
When dividing 66 by 13, we get 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 55.0
If we take 65 away from 66, we end up with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 13

Let's proceed to step 4:
When dividing 13 by 13, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 551.0
Subtracting 13 from 13 leaves us with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 13

Step 5:
13 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 5510.0
If we take 0 away from 2, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 13

Going ahead to step 6:
21 divided by 13 is 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 55101.0
The remainder is 8 after subtracting 13 from 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
13 can be fit into 80 6 times, resulting in a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 55101.6
If we take 78 away from 80, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
The number 13 fits into 20 1 times, leaving a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 55101.61
The remainder is 7 after subtracting 13 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 9:
If we divide 70 by 13, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 55101.615
The remainder is 5 after subtracting 65 from 70.
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 10:
50 divided by 13 is 3 with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 55101.6153
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 11:
13 goes into 110 8 times with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 55101.61538
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.

Let's proceed to step 12:
The number 13 fits into 60 4 times, leaving a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 55101.615384
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 13:
13 goes into 80 6 times with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 55101.6153846
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 14:
13 goes into 20 1 times with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 55101.61538461
The remainder is 7 after subtracting 13 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The quotient of the division is 55101.61538461, and the remainder is 7e-09.
