550689 ÷ 12 
The aim is to understand the frequency of 12 in 550689.

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.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 12

Moving on to step 2:
If we divide 55 by 12, we get 4 and a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 48 from 55 leaves us with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 12

Moving on to step 3:
If we divide 70 by 12, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Subtract 60 from 70 to get 10.
Append the next digit (6) from the dividend to 10 and continue with: 106 / 12

Step 4:
When dividing 106 by 12, we get 8 with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 458.0
If we subtract 96 from 106, we get 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 12

Going ahead to step 5:
The number 12 fits into 108 9 times, leaving a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 4589.0
Subtract 108 from 108 to get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 12

Let's proceed to step 6:
If we divide 9 by 12, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 45890.0
If we take 0 away from 9, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
When dividing 90 by 12, we get 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 45890.7
Subtract 84 from 90 to 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:
60 divided by 12 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 45890.75
The remainder is 0 after subtracting 60 from 60.
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 9:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 45890.75
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 45890.75
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 final result is 45890.75 with a remainder of 0.0.
