Let's divide 148624 by 12
The aim is to understand the frequency of 12 in 148624.

Moving on to step 1:
When dividing 1 by 12, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 12

Going ahead to step 2:
12 can be fit into 14 1 times, resulting in a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 12 from 14 to get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 12

Advancing to step 3:
When dividing 28 by 12, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 24 from 28 leaves us with 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 12

Going ahead to step 4:
When dividing 46 by 12, we get 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 123.0
Subtracting 36 from 46 leaves us with 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 12

Advancing to step 5:
12 can be fit into 102 8 times, resulting in a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 1238.0
Subtract 96 from 102 to get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 12

Moving on to step 6:
The number 12 fits into 64 5 times, leaving a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 12385.0
Subtract 60 from 64 to 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.

Advancing to step 7:
If we divide 40 by 12, we get 3 and a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 12385.3
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.

On to step 8:
12 goes into 40 3 times with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 12385.33
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 final outcome is 12385.33, with a leftover of 0.004.
