We're dividing 731430 by 13 
The aim is to understand the frequency of 13 in 731430.

Moving on 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
Deduct 0 from 7 and we're left with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 13

Let's proceed to step 2:
13 goes into 73 5 times with a remainder of 8.
The next digit of our result is 5. 
Result so far: 5.0
If we take 65 away from 73, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 13

Moving on to step 3:
The number 13 fits into 81 6 times, leaving a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 56.0
If we take 78 away from 81, we end up with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 13

Step 4:
34 divided by 13 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 562.0
The remainder is 8 after subtracting 26 from 34.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 13

On to step 5:
When dividing 83 by 13, we get 6 with a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 5626.0
If we subtract 78 from 83, we get 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 13

Going ahead to step 6:
13 goes into 50 3 times with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 56263.0
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.

Step 7:
If we divide 110 by 13, we get 8 and a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 56263.8
Subtracting 104 from 110 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
13 goes into 60 4 times with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 56263.84
Subtract 52 from 60 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.

Step 9:
The number 13 fits into 80 6 times, leaving a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 56263.846
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.

Let's proceed to step 10:
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: 56263.8461
If we subtract 13 from 20, we get 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 11:
70 divided by 13 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 56263.84615
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.

On to step 12:
The number 13 fits into 50 3 times, leaving a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 56263.846153
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.

On to step 13:
The number 13 fits into 110 8 times, leaving a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 56263.8461538
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.

Step 14:
60 divided by 13 is 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 56263.84615384
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.

Our division results in 56263.84615384 with a remaining 8e-09.
