Let's divide 771805 by 13
The aim is to understand the frequency of 13 in 771805.

Advancing to step 1:
The number 13 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 13

Let's proceed to step 2:
When dividing 77 by 13, we get 5 with a remainder of 12.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 65 away from 77, we end up with 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 13

Let's proceed to step 3:
121 divided by 13 is 9 with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 59.0
If we subtract 117 from 121, we get 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 13

Step 4:
13 goes into 48 3 times with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 593.0
Subtract 39 from 48 to get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 13

Step 5:
13 can be fit into 90 6 times, resulting in a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 5936.0
The remainder is 12 after subtracting 78 from 90.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 13

Advancing to step 6:
When dividing 125 by 13, we get 9 with a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 59369.0
Subtract 117 from 125 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
13 can be fit into 80 6 times, resulting in a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 59369.6
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 8:
The number 13 fits into 20 1 times, leaving a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 59369.61
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.

Going ahead to step 9:
If we divide 70 by 13, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 59369.615
If we subtract 65 from 70, 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.

Moving on to step 10:
50 divided by 13 is 3 with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 59369.6153
Subtracting 39 from 50 leaves us 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 11:
13 goes into 110 8 times with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 59369.61538
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.

Advancing to step 12:
13 can be fit into 60 4 times, resulting in a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 59369.615384
If we subtract 52 from 60, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 13:
13 can be fit into 80 6 times, resulting in a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 59369.6153846
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.

Let's proceed to step 14:
When dividing 20 by 13, we get 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 59369.61538461
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 59369.61538461, and the remainder is 7e-09.
