91876340 ÷ 12 
The aim is to understand the frequency of 12 in 91876340.

Moving on to step 1:
9 divided by 12 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 12

Step 2:
The number 12 fits into 91 7 times, leaving a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 84 from 91 leaves us with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 12

Going ahead to step 3:
When dividing 78 by 12, we get 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 76.0
Subtracting 72 from 78 leaves us with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 12

Moving on to step 4:
12 can be fit into 67 5 times, resulting in a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 765.0
The remainder is 7 after subtracting 60 from 67.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 12

Let's proceed to step 5:
When dividing 76 by 12, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 7656.0
The remainder is 4 after subtracting 72 from 76.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 12

On to step 6:
When dividing 43 by 12, we get 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 76563.0
If we take 36 away from 43, we end up with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 12

Moving on to step 7:
12 goes into 74 6 times with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 765636.0
The remainder is 2 after subtracting 72 from 74.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 12

Going ahead to step 8:
12 goes into 20 1 times with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 7656361.0
If we take 12 away from 20, we end up 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.

Moving on to step 9:
The number 12 fits into 80 6 times, leaving a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 7656361.6
Subtracting 72 from 80 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.

Advancing to step 10:
80 divided by 12 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 7656361.66
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 7656361.66 with a balance of 0.008.
