We're dividing 945272 by 12 
The aim is to understand the frequency of 12 in 945272.

On to step 1:
When dividing 9 by 12, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 12

Advancing to step 2:
12 can be fit into 94 7 times, resulting in a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 84 away from 94, we end up with 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 12

Moving on to step 3:
When dividing 105 by 12, we get 8 with a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
Subtracting 96 from 105 leaves us with 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 12

Moving on to step 4:
12 can be fit into 92 7 times, resulting in a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 787.0
Subtracting 84 from 92 leaves us with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 12

Step 5:
12 can be fit into 87 7 times, resulting in a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 7877.0
Subtract 84 from 87 to get 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 12

On to step 6:
12 can be fit into 32 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 78772.0
Deduct 24 from 32 and we're left 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.

Let's proceed to step 7:
12 can be fit into 80 6 times, resulting in a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 78772.6
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.

Going ahead to step 8:
80 divided by 12 is 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 78772.66
Subtract 72 from 80 to 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.

After the division, we end up with 78772.66 and a remainder of 0.008.
