We divide 220622 by 12
The aim is to understand the frequency of 12 in 220622.

Moving on to step 1:
When dividing 2 by 12, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 12

On to step 2:
22 divided by 12 is 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 10 after subtracting 12 from 22.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 12

Advancing to step 3:
12 can be fit into 100 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtracting 96 from 100 leaves us with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 12

Moving on to step 4:
12 can be fit into 46 3 times, resulting in a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 183.0
If we subtract 36 from 46, we get 10.
Bring next digit (2) of the dividend behind the 10 and repeat the process: 102 / 12

Advancing to step 5:
The number 12 fits into 102 8 times, leaving a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 1838.0
Subtracting 96 from 102 leaves us with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 12

Moving on to step 6:
When dividing 62 by 12, we get 5 with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 18385.0
Subtract 60 from 62 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
When dividing 20 by 12, we get 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 18385.1
The remainder is 8 after subtracting 12 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
The number 12 fits into 80 6 times, leaving a remainder of 8.
The next digit of our result is 6. 
Result so far: 18385.16
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
80 divided by 12 is 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 18385.166
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 18385.166, with a leftover of 0.0008.
