17596 divided by 13 
The aim is to understand the frequency of 13 in 17596.

On to step 1:
If we divide 1 by 13, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 13

Advancing to step 2:
17 divided by 13 is 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 13 from 17, we get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 13

Advancing to step 3:
45 divided by 13 is 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 39 from 45 leaves us with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 13

Let's proceed to step 4:
13 goes into 69 5 times with a remainder of 4.
The next digit of our result is 5. 
Result so far: 135.0
Deduct 65 from 69 and we're left with 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 13

Moving on to step 5:
When dividing 46 by 13, we get 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 1353.0
If we take 39 away from 46, we end up 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.

Advancing to step 6:
13 can be fit into 70 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 1353.5
If we take 65 away from 70, we end up 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.

Advancing to step 7:
The number 13 fits into 50 3 times, leaving a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 1353.53
If we subtract 39 from 50, we 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.

Moving on to step 8:
When dividing 110 by 13, we get 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 1353.538
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.

Advancing to step 9:
When dividing 60 by 13, we get 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 1353.5384
Deduct 52 from 60 and we're left 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.

Step 10:
The number 13 fits into 80 6 times, leaving a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 1353.53846
Subtract 78 from 80 to 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 11:
If we divide 20 by 13, we get 1 and a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1353.538461
If we take 13 away from 20, we end up 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 12:
70 divided by 13 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 1353.5384615
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 13:
When dividing 50 by 13, we get 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 1353.53846153
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 1353.53846153 with a remaining 1.1e-08.
