727638 divided by 13 
The aim is to understand the frequency of 13 in 727638.

Going ahead 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.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 13

Moving on to step 2:
13 goes into 72 5 times with a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 65 away from 72, we end up with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 13

Let's proceed to step 3:
13 goes into 77 5 times with a remainder of 12.
Put 5 as the next digit of the answer. 
Result so far: 55.0
The remainder is 12 after subtracting 65 from 77.
Append the next digit (6) from the dividend to 12 and continue with: 126 / 13

Let's proceed to step 4:
When dividing 126 by 13, we get 9 with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 559.0
The remainder is 9 after subtracting 117 from 126.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 13

On to step 5:
13 can be fit into 93 7 times, resulting in a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 5597.0
Subtracting 91 from 93 leaves us with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 13

Going ahead to step 6:
28 divided by 13 is 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 55972.0
If we subtract 26 from 28, 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 7:
The number 13 fits into 20 1 times, leaving a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 55972.1
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 8:
70 divided by 13 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 55972.15
Subtract 65 from 70 to 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 9:
13 goes into 50 3 times with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 55972.153
The remainder is 11 after subtracting 39 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 10:
If we divide 110 by 13, we get 8 and a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 55972.1538
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 11:
13 goes into 60 4 times with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 55972.15384
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.

Advancing to step 12:
The number 13 fits into 80 6 times, leaving a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 55972.153846
Subtracting 78 from 80 leaves us 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 13:
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: 55972.1538461
Subtracting 13 from 20 leaves us 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.

Let's proceed to step 14:
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: 55972.15384615
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.

The quotient of the division is 55972.15384615, and the remainder is 5e-09.
