We divide 551073 by 12
The aim is to understand the frequency of 12 in 551073.

Moving on to step 1:
The number 12 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 12

Moving on to step 2:
When dividing 55 by 12, we get 4 with a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 48 away from 55, we end up with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 12

On to step 3:
12 goes into 71 5 times with a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
Subtract 60 from 71 to get 11.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 12

Moving on to step 4:
The number 12 fits into 110 9 times, leaving a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 459.0
Subtract 108 from 110 to get 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 12

Moving on to step 5:
When dividing 27 by 12, we get 2 with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 4592.0
If we take 24 away from 27, we end up with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 12

Advancing to step 6:
33 divided by 12 is 2 with a remainder of 9.
The next digit of our result is 2. 
Result so far: 45922.0
If we subtract 24 from 33, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
The number 12 fits into 90 7 times, leaving a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 45922.7
If we subtract 84 from 90, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
The number 12 fits into 60 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 45922.75
Subtract 60 from 60 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
When dividing 0 by 12, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 45922.75
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 45922.75
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 45922.75, and the remainder is 0.0.
