We divide 146412 by 12
The aim is to understand the frequency of 12 in 146412.

Advancing to step 1:
If we divide 1 by 12, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 12

Let's proceed to step 2:
14 divided by 12 is 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 12 from 14 and we're left with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 12

Step 3:
The number 12 fits into 26 2 times, leaving a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 24 away from 26, we end up with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 12

Advancing to step 4:
When dividing 24 by 12, we get 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 122.0
The remainder is 0 after subtracting 24 from 24.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 12

Advancing to step 5:
If we divide 1 by 12, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 1220.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 12

Step 6:
If we divide 12 by 12, we get 1 and a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 12201.0
Deduct 12 from 12 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.

Let's proceed to step 7:
The number 12 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 12201.0
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.

Let's proceed to step 8:
0 divided by 12 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12201.0
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.

The final outcome is 12201.0, with a leftover of 0.0.
