We divide 436411 by 12
The aim is to understand the frequency of 12 in 436411.

Going ahead to step 1:
12 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 12

Moving on to step 2:
12 goes into 43 3 times with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 36 from 43 to get 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 12

Moving on to step 3:
12 can be fit into 76 6 times, resulting in a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 36.0
The remainder is 4 after subtracting 72 from 76.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 12

Step 4:
The number 12 fits into 44 3 times, leaving a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 363.0
Deduct 36 from 44 and we're left with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 12

Advancing to step 5:
12 can be fit into 81 6 times, resulting in a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 3636.0
If we subtract 72 from 81, we get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 12

Moving on to step 6:
91 divided by 12 is 7 with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 36367.0
Deduct 84 from 91 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
The number 12 fits into 70 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 36367.5
If we subtract 60 from 70, we get 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 8:
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: 36367.58
If we take 96 away from 100, 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.

On to step 9:
40 divided by 12 is 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 36367.583
If we subtract 36 from 40, we get 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 10:
If we divide 40 by 12, we get 3 and a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 36367.5833
Deduct 36 from 40 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.

The final result is 36367.5833 with a remainder of 4e-05.
