We look at the division of 733660 by 12 
The aim is to understand the frequency of 12 in 733660.

Let's proceed to step 1:
If we divide 7 by 12, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 12

Let's proceed to step 2:
73 divided by 12 is 6 with a remainder of 1.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 72 from 73 and we're left with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 12

Going ahead to step 3:
The number 12 fits into 13 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 61.0
Subtract 12 from 13 to get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 12

Step 4:
12 goes into 16 1 times with a remainder of 4.
The next digit of our result is 1. 
Result so far: 611.0
Subtract 12 from 16 to get 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 12

Moving on to step 5:
If we divide 46 by 12, we get 3 and a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 6113.0
Subtract 36 from 46 to get 10.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 12

Advancing to step 6:
12 goes into 100 8 times with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 61138.0
The remainder is 4 after subtracting 96 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 61138.3
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 61138.33
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 61138.33 with a remainder of 0.004.
