We look at the division of 8106 by 12 
The aim is to understand the frequency of 12 in 8106.

Moving on to step 1:
The number 12 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 12

On to step 2:
The number 12 fits into 81 6 times, leaving a remainder of 9.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 72 from 81 and we're left with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 12

Advancing to step 3:
If we divide 90 by 12, we get 7 and a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 67.0
The remainder is 6 after subtracting 84 from 90.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 12

Moving on to step 4:
12 goes into 66 5 times with a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 675.0
Subtract 60 from 66 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.

Moving on to step 5:
The number 12 fits into 60 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 675.5
Deduct 60 from 60 and we're left 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.

Going ahead to step 6:
If we divide 0 by 12, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 675.5
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.

Moving on to step 7:
12 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 675.5
Subtract 0 from 0 to 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 675.5 with a remainder of 0.0.
