We divide 653816 by 13
The aim is to understand the frequency of 13 in 653816.

On to step 1:
If we divide 6 by 13, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 13

Moving on to step 2:
13 goes into 65 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 0 after subtracting 65 from 65.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 13

Advancing to step 3:
3 divided by 13 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 50.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 13

Advancing to step 4:
38 divided by 13 is 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 502.0
Deduct 26 from 38 and we're left with 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 13

Going ahead to step 5:
121 divided by 13 is 9 with a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 5029.0
The remainder is 4 after subtracting 117 from 121.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 13

Step 6:
The number 13 fits into 46 3 times, leaving a remainder of 7.
The next digit of our result is 3. 
Result so far: 50293.0
The remainder is 7 after subtracting 39 from 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
70 divided by 13 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 50293.5
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.

Going ahead to step 8:
13 can be fit into 50 3 times, resulting in a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 50293.53
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.

Advancing to step 9:
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: 50293.538
If we subtract 104 from 110, we 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.

On to step 10:
13 can be fit into 60 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 50293.5384
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.

Going ahead to step 11:
13 can be fit into 80 6 times, resulting in a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 50293.53846
If we take 78 away from 80, we end up 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.

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: 50293.538461
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.

Advancing to step 13:
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: 50293.5384615
If we subtract 65 from 70, we 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.

On to step 14:
If we divide 50 by 13, we get 3 and a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 50293.53846153
Subtract 39 from 50 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Our division results in 50293.53846153 with a remaining 1.1e-08.
