91816026 ÷ 12 
The aim is to understand the frequency of 12 in 91816026.

Let's proceed to step 1:
12 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 12

Let's proceed to step 2:
The number 12 fits into 91 7 times, leaving a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 7 after subtracting 84 from 91.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 12

Step 3:
78 divided by 12 is 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 76.0
If we subtract 72 from 78, we get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 12

Moving on to step 4:
When dividing 61 by 12, we get 5 with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 765.0
Deduct 60 from 61 and we're left with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 12

On to step 5:
16 divided by 12 is 1 with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 7651.0
Subtracting 12 from 16 leaves us with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 12

Step 6:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 76513.0
The remainder is 4 after subtracting 36 from 40.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 12

Let's proceed to step 7:
The number 12 fits into 42 3 times, leaving a remainder of 6.
The next digit of our result is 3. 
Result so far: 765133.0
If we take 36 away from 42, we end up with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 12

Step 8:
12 goes into 66 5 times with a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 7651335.0
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 9:
12 goes into 60 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 7651335.5
If we subtract 60 from 60, 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.

Advancing to step 10:
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: 7651335.5
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.

Going ahead to step 11:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7651335.5
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.

Our division results in 7651335.5 with a remaining 0.0.
