Let's divide 801241 by 12
The aim is to understand the frequency of 12 in 801241.

Moving on to step 1:
The number 12 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 12

Advancing to step 2:
If we divide 80 by 12, we get 6 and a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 72 from 80, we get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 12

Let's proceed to step 3:
81 divided by 12 is 6 with a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 66.0
If we subtract 72 from 81, we get 9.
Bring next digit (2) of the dividend behind the 9 and repeat the process: 92 / 12

Moving on to step 4:
92 divided by 12 is 7 with a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 667.0
Subtract 84 from 92 to get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 12

Going ahead to step 5:
If we divide 84 by 12, we get 7 and a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 6677.0
Deduct 84 from 84 and we're left with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 12

Step 6:
When dividing 1 by 12, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 66770.0
If we subtract 0 from 1, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
10 divided by 12 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 66770.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
12 goes into 100 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 66770.08
If we take 96 away from 100, we end up 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.

Going ahead to step 9:
40 divided by 12 is 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 66770.083
If we take 36 away from 40, we end up 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.

Moving on to step 10:
40 divided by 12 is 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 66770.0833
If we subtract 36 from 40, we 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.

The final result is 66770.0833 with a remainder of 4e-05.
