We look at the division of 586183 by 12 
The aim is to understand the frequency of 12 in 586183.

Moving on to step 1:
If we divide 5 by 12, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 12

Moving on to step 2:
If we divide 58 by 12, we get 4 and a remainder of 10.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 48 from 58 to get 10.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 12

Advancing to step 3:
106 divided by 12 is 8 with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
If we subtract 96 from 106, we get 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 12

Going ahead to step 4:
When dividing 101 by 12, we get 8 with a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 488.0
Deduct 96 from 101 and we're left with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 12

On to step 5:
The number 12 fits into 58 4 times, leaving a remainder of 10.
The next digit of our result is 4. 
Result so far: 4884.0
The remainder is 10 after subtracting 48 from 58.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 12

Going ahead to step 6:
12 goes into 103 8 times with a remainder of 7.
The next digit of our result is 8. 
Result so far: 48848.0
If we take 96 away from 103, we end up 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.

Step 7:
If we divide 70 by 12, we get 5 and a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 48848.5
If we take 60 away from 70, 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.

Going ahead to step 8:
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: 48848.58
Subtracting 96 from 100 leaves us 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.

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: 48848.583
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.

Let's proceed to step 10:
The number 12 fits into 40 3 times, leaving a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 48848.5833
Subtracting 36 from 40 leaves us 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 quotient of the division is 48848.5833, and the remainder is 4e-05.
