Let's divide 491655 by 12
The aim is to understand the frequency of 12 in 491655.

Advancing to step 1:
The number 12 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 12

Step 2:
49 divided by 12 is 4 with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 48 away from 49, we end up with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 12

Advancing to step 3:
The number 12 fits into 11 0 times, leaving a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
If we take 0 away from 11, we end up with 11.
Bring next digit (6) of the dividend behind the 11 and repeat the process: 116 / 12

Moving on to step 4:
When dividing 116 by 12, we get 9 with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 409.0
If we subtract 108 from 116, we get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 12

On to step 5:
The number 12 fits into 85 7 times, leaving a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 4097.0
If we subtract 84 from 85, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 12

Going ahead to step 6:
15 divided by 12 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 40971.0
Subtract 12 from 15 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
When dividing 30 by 12, we get 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 40971.2
Subtract 24 from 30 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.

On to step 8:
60 divided by 12 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 40971.25
Deduct 60 from 60 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 9:
12 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 40971.25
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:
If we divide 0 by 12, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 40971.25
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.

Our division results in 40971.25 with a remaining 0.0.
