Let's divide 370809 by 12
The aim is to understand the frequency of 12 in 370809.

Moving on to step 1:
If we divide 3 by 12, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 12

Let's proceed to step 2:
The number 12 fits into 37 3 times, leaving a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 36 from 37, we get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 12

Advancing to step 3:
The number 12 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 30.0
Subtracting 0 from 10 leaves us with 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 12

Step 4:
The number 12 fits into 108 9 times, leaving a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 309.0
The remainder is 0 after subtracting 108 from 108.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 12

Going ahead to step 5:
If we divide 0 by 12, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3090.0
Deduct 0 from 0 and we're left with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 12

On to step 6:
9 divided by 12 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 30900.0
If we subtract 0 from 9, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
12 can be fit into 90 7 times, resulting in a remainder of 6.
The next digit of our result is 7. 
Result so far: 30900.7
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.

Step 8:
12 can be fit into 60 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 30900.75
Subtracting 60 from 60 leaves us 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.

Going ahead to step 9:
When dividing 0 by 12, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 30900.75
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 10:
When dividing 0 by 12, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 30900.75
Subtract 0 from 0 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.

The quotient of the division is 30900.75, and the remainder is 0.0.
