We divide 591670 by 12
The aim is to understand the frequency of 12 in 591670.

Going ahead to step 1:
12 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 12

Let's proceed to step 2:
12 goes into 59 4 times with a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 11 after subtracting 48 from 59.
Append the next digit (1) from the dividend to 11 and continue with: 111 / 12

On to step 3:
If we divide 111 by 12, we get 9 and a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 49.0
Subtract 108 from 111 to get 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 12

On to step 4:
12 goes into 36 3 times with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 493.0
Deduct 36 from 36 and we're left with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 12

Advancing to step 5:
12 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 4930.0
If we subtract 0 from 7, we get 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 12

Step 6:
12 can be fit into 70 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 49305.0
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.

Let's proceed to step 7:
The number 12 fits into 100 8 times, leaving a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 49305.8
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.

On to step 8:
When dividing 40 by 12, we get 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 49305.83
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.

Moving on to step 9:
40 divided by 12 is 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 49305.833
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.

In conclusion, the division gives 49305.833 with a balance of 0.0004.
