Let's divide 8112 by 13
The aim is to understand the frequency of 13 in 8112.

Advancing to step 1:
When dividing 8 by 13, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 13

Advancing to step 2:
13 can be fit into 81 6 times, resulting in a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 78 from 81 leaves us with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 13

Moving on to step 3:
If we divide 31 by 13, we get 2 and a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 62.0
Subtract 26 from 31 to get 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 13

Advancing to step 4:
When dividing 52 by 13, we get 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 624.0
If we take 52 away from 52, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 5:
The number 13 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 624.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 6:
If we divide 0 by 13, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 624.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 624.0 with a remainder of 0.0.
