Let's divide 89673311 by 12
The aim is to understand the frequency of 12 in 89673311.

Advancing to step 1:
12 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 12

Advancing to step 2:
12 goes into 89 7 times with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 84 from 89 and we're left with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 12

Let's proceed to step 3:
56 divided by 12 is 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 74.0
If we subtract 48 from 56, we get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 12

Let's proceed to step 4:
When dividing 87 by 12, we get 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 747.0
If we take 84 away from 87, we end up with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 12

On to step 5:
The number 12 fits into 33 2 times, leaving a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 7472.0
The remainder is 9 after subtracting 24 from 33.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 12

Step 6:
12 goes into 93 7 times with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 74727.0
Deduct 84 from 93 and we're left with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 12

Advancing to step 7:
When dividing 91 by 12, we get 7 with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 747277.0
If we take 84 away from 91, we end up with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 12

Let's proceed to step 8:
When dividing 71 by 12, we get 5 with a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 7472775.0
Deduct 60 from 71 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.

Step 9:
When dividing 110 by 12, we get 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 7472775.9
Deduct 108 from 110 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
When dividing 20 by 12, we get 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 7472775.91
Subtracting 12 from 20 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.

Moving on to step 11:
When dividing 80 by 12, we get 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 7472775.916
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
80 divided by 12 is 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 7472775.9166
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.

Our division results in 7472775.9166 with a remaining 8e-05.
