We're dividing 356073 by 12 
The aim is to understand the frequency of 12 in 356073.

Step 1:
The number 12 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 12

Step 2:
12 can be fit into 35 2 times, resulting in a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 24 away from 35, we end up with 11.
Append the next digit (6) from the dividend to 11 and continue with: 116 / 12

Going ahead to step 3:
When dividing 116 by 12, we get 9 with a remainder of 8.
The next digit of our result is 9. 
Result so far: 29.0
Subtracting 108 from 116 leaves us with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 12

Advancing to step 4:
When dividing 80 by 12, we get 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 296.0
Subtracting 72 from 80 leaves us with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 12

Step 5:
12 can be fit into 87 7 times, resulting in a remainder of 3.
The next digit of our result is 7. 
Result so far: 2967.0
Subtract 84 from 87 to get 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 12

Moving on to step 6:
The number 12 fits into 33 2 times, leaving a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 29672.0
Subtracting 24 from 33 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
The number 12 fits into 90 7 times, leaving a remainder of 6.
The next digit of our result is 7. 
Result so far: 29672.7
If we take 84 away from 90, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
60 divided by 12 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 29672.75
Subtract 60 from 60 to 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.

Let's proceed to step 9:
When dividing 0 by 12, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 29672.75
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.

Let's proceed to step 10:
0 divided by 12 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 29672.75
The remainder is 0 after subtracting 0 from 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 29672.75 and a remainder of 0.0.
