We're dividing 395675 by 13 
The aim is to understand the frequency of 13 in 395675.

On to step 1:
If we divide 3 by 13, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 13

Let's proceed to step 2:
13 goes into 39 3 times with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 39 from 39 and we're left with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 13

Going ahead to step 3:
5 divided by 13 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 30.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 13

Moving on to step 4:
56 divided by 13 is 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 304.0
If we take 52 away from 56, we end up with 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 13

On to step 5:
13 can be fit into 47 3 times, resulting in a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 3043.0
Subtract 39 from 47 to get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 13

Let's proceed to step 6:
The number 13 fits into 85 6 times, leaving a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 30436.0
If we subtract 78 from 85, 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 7:
13 goes into 70 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 30436.5
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.

On to step 8:
50 divided by 13 is 3 with a remainder of 11.
The next digit of our result is 3. 
Result so far: 30436.53
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.

Going ahead to step 9:
When dividing 110 by 13, we get 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 30436.538
Deduct 104 from 110 and we're left 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.

Going ahead to step 10:
13 can be fit into 60 4 times, resulting in a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 30436.5384
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 11:
When dividing 80 by 13, we get 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 30436.53846
Deduct 78 from 80 and we're left 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 12:
13 can be fit into 20 1 times, resulting in a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 30436.538461
Deduct 13 from 20 and we're left 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.

Moving on to step 13:
13 can be fit into 70 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 30436.5384615
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.

Step 14:
13 can be fit into 50 3 times, resulting in a remainder of 11.
The next digit of our result is 3. 
Result so far: 30436.53846153
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.

The quotient of the division is 30436.53846153, and the remainder is 1.1e-08.
