We're dividing 556051 by 12 
The aim is to understand the frequency of 12 in 556051.

Let's proceed to step 1:
If we divide 5 by 12, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 12

Advancing to step 2:
The number 12 fits into 55 4 times, leaving a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 48 from 55 leaves us with 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 12

On to step 3:
12 can be fit into 76 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 46.0
The remainder is 4 after subtracting 72 from 76.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 12

Step 4:
12 goes into 40 3 times with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 463.0
The remainder is 4 after subtracting 36 from 40.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 12

Moving on to step 5:
12 can be fit into 45 3 times, resulting in a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 4633.0
Deduct 36 from 45 and we're left with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 12

Moving on to step 6:
12 goes into 91 7 times with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 46337.0
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.

Advancing to step 7:
When dividing 70 by 12, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 46337.5
Subtract 60 from 70 to 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.

Advancing to step 8:
12 can be fit into 100 8 times, resulting in a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 46337.58
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.

On to step 9:
12 goes into 40 3 times with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 46337.583
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.

Going ahead 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: 46337.5833
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 46337.5833 with a remainder of 4e-05.
