We're dividing 919920 by 12 
The aim is to understand the frequency of 12 in 919920.

Let's proceed to step 1:
9 divided by 12 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 12

Let's proceed to step 2:
12 can be fit into 91 7 times, resulting in a remainder of 7.
The next digit of our result is 7. 
Result so far: 7.0
If we take 84 away from 91, we end up with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 12

On to step 3:
79 divided by 12 is 6 with a remainder of 7.
The next digit of our result is 6. 
Result so far: 76.0
Deduct 72 from 79 and we're left with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 12

Going ahead to step 4:
When dividing 79 by 12, we get 6 with a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 766.0
Subtract 72 from 79 to get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 12

On to step 5:
If we divide 72 by 12, we get 6 and a remainder of 0.
The next digit of our result is 6. 
Result so far: 7666.0
Subtracting 72 from 72 leaves us with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 12

On to step 6:
0 divided by 12 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 76660.0
Deduct 0 from 0 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.

Let's proceed to step 7:
The number 12 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 76660.0
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.

Moving on to step 8:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 76660.0
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.

After the division, we end up with 76660.0 and a remainder of 0.0.
