Let's divide 112536 by 13
The aim is to understand the frequency of 13 in 112536.

Moving on to step 1:
When dividing 1 by 13, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 13

Advancing to step 2:
The number 13 fits into 11 0 times, leaving a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 11, we get 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 13

Advancing to step 3:
When dividing 112 by 13, we get 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 104 away from 112, we end up with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 13

Moving on to step 4:
85 divided by 13 is 6 with a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 86.0
Deduct 78 from 85 and we're left with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 13

Advancing to step 5:
73 divided by 13 is 5 with a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 865.0
If we take 65 away from 73, we end up with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 13

Going ahead to step 6:
86 divided by 13 is 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 8656.0
Subtracting 78 from 86 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.

Let's proceed to step 7:
80 divided by 13 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 8656.6
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
13 can be fit into 20 1 times, resulting in a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 8656.61
Subtract 13 from 20 to 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 9:
70 divided by 13 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 8656.615
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.

On to step 10:
13 goes into 50 3 times with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 8656.6153
Deduct 39 from 50 and we're left 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.

Moving on to step 11:
When dividing 110 by 13, we get 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 8656.61538
Subtracting 104 from 110 leaves us 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.

On to step 12:
If we divide 60 by 13, we get 4 and a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 8656.615384
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.

Advancing to step 13:
The number 13 fits into 80 6 times, leaving a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 8656.6153846
The remainder is 2 after subtracting 78 from 80.
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 14:
When dividing 20 by 13, we get 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 8656.61538461
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.

The final result is 8656.61538461 with a remainder of 7e-09.
