We divide 447598 by 12
The aim is to understand the frequency of 12 in 447598.

Advancing to step 1:
4 divided by 12 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 12

Let's proceed to step 2:
If we divide 44 by 12, we get 3 and a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 8 after subtracting 36 from 44.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 12

Step 3:
The number 12 fits into 87 7 times, leaving a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 37.0
If we subtract 84 from 87, we get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 12

Advancing to step 4:
The number 12 fits into 35 2 times, leaving a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 372.0
If we take 24 away from 35, we end up with 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 12

Going ahead to step 5:
The number 12 fits into 119 9 times, leaving a remainder of 11.
The next digit of our result is 9. 
Result so far: 3729.0
If we subtract 108 from 119, we get 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 12

Advancing to step 6:
118 divided by 12 is 9 with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 37299.0
If we take 108 away from 118, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
If we divide 100 by 12, we get 8 and a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 37299.8
Deduct 96 from 100 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
If we divide 40 by 12, we get 3 and a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 37299.83
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
12 can be fit into 40 3 times, resulting in a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 37299.833
If we take 36 away from 40, we end up with 4.
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 37299.833 with a remainder of 0.0004.
