Let's divide 581614 by 13
The aim is to understand the frequency of 13 in 581614.

On to step 1:
When dividing 5 by 13, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 13

Let's proceed to step 2:
If we divide 58 by 13, we get 4 and a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 52 away from 58, we end up with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 13

Let's proceed to step 3:
13 goes into 61 4 times with a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 44.0
If we subtract 52 from 61, we get 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 13

On to step 4:
If we divide 96 by 13, we get 7 and a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 447.0
Deduct 91 from 96 and we're left with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 13

Going ahead to step 5:
13 goes into 51 3 times with a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 4473.0
If we subtract 39 from 51, we get 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 13

Advancing to step 6:
The number 13 fits into 124 9 times, leaving a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 44739.0
Subtracting 117 from 124 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.

Moving on to step 7:
13 can be fit into 70 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 44739.5
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.

Step 8:
13 can be fit into 50 3 times, resulting in a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 44739.53
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.

Advancing to step 9:
13 can be fit into 110 8 times, resulting in a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 44739.538
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 10:
13 can be fit into 60 4 times, resulting in a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 44739.5384
The remainder is 8 after subtracting 52 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
13 goes into 80 6 times with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 44739.53846
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.

Step 12:
When dividing 20 by 13, we get 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 44739.538461
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.

Let's proceed to step 13:
When dividing 70 by 13, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 44739.5384615
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.

Moving on to step 14:
50 divided by 13 is 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 44739.53846153
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.

Our division results in 44739.53846153 with a remaining 1.1e-08.
