We're dividing 355214 by 13 
The aim is to understand the frequency of 13 in 355214.

On to step 1:
The number 13 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 13

Let's proceed to step 2:
13 goes into 35 2 times with a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 26 from 35 leaves us with 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 13

Going ahead to step 3:
The number 13 fits into 95 7 times, leaving a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Deduct 91 from 95 and we're left with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 13

Let's proceed to step 4:
When dividing 42 by 13, we get 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 273.0
Deduct 39 from 42 and we're left with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 13

Let's proceed to step 5:
31 divided by 13 is 2 with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 2732.0
If we subtract 26 from 31, we get 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 13

Advancing to step 6:
54 divided by 13 is 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 27324.0
Subtracting 52 from 54 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.

Moving on to step 7:
20 divided by 13 is 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 27324.1
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.

Step 8:
70 divided by 13 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 27324.15
Deduct 65 from 70 and we're left 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.

Let's proceed to step 9:
13 goes into 50 3 times with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 27324.153
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.

Let's proceed to step 10:
13 can be fit into 110 8 times, resulting in a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 27324.1538
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 11:
60 divided by 13 is 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 27324.15384
Subtracting 52 from 60 leaves us 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.

Moving on to step 12:
13 goes into 80 6 times with a remainder of 2.
The next digit of our result is 6. 
Result so far: 27324.153846
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.

On to step 13:
If we divide 20 by 13, we get 1 and a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 27324.1538461
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.

On to step 14:
If we divide 70 by 13, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 27324.15384615
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 27324.15384615, and the remainder is 5e-09.
