773945 ÷ 13 
The aim is to understand the frequency of 13 in 773945.

Let's proceed to step 1:
13 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 13

Let's proceed to step 2:
13 can be fit into 77 5 times, resulting in a remainder of 12.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 65 from 77 and we're left with 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 13

On to step 3:
13 goes into 123 9 times with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 59.0
If we subtract 117 from 123, we get 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 13

Step 4:
13 goes into 69 5 times with a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 595.0
Subtract 65 from 69 to get 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 13

Step 5:
13 can be fit into 44 3 times, resulting in a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 5953.0
If we take 39 away from 44, we end up with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 13

Going ahead to step 6:
If we divide 55 by 13, we get 4 and a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 59534.0
If we subtract 52 from 55, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
The number 13 fits into 30 2 times, leaving a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 59534.2
Deduct 26 from 30 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
40 divided by 13 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 59534.23
Subtracting 39 from 40 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
10 divided by 13 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 59534.23
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
100 divided by 13 is 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 59534.2307
If we take 91 away from 100, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 11:
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: 59534.23076
Subtracting 78 from 90 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
When dividing 120 by 13, we get 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 59534.230769
Deduct 117 from 120 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 13:
When dividing 30 by 13, we get 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 59534.2307692
Subtracting 26 from 30 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 14:
When dividing 40 by 13, we get 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 59534.23076923
Deduct 39 from 40 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 59534.23076923 and a remainder of 1e-09.
