We look at the division of 921072 by 6 
The aim is to understand the frequency of 6 in 921072.

Let's proceed to step 1:
9 divided by 6 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 6 from 9 to get 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 6

Moving on to step 2:
If we divide 32 by 6, we get 5 and a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 30 from 32 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 6

Let's proceed to step 3:
If we divide 21 by 6, we get 3 and a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 153.0
Subtract 18 from 21 to get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 6

Let's proceed to step 4:
The number 6 fits into 30 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 1535.0
The remainder is 0 after subtracting 30 from 30.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 6

Moving on to step 5:
When dividing 7 by 6, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 15351.0
Subtract 6 from 7 to get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 6

Going ahead to step 6:
The number 6 fits into 12 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 153512.0
Subtracting 12 from 12 leaves us 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.

Moving on to step 7:
The number 6 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 153512.0
Subtract 0 from 0 to get 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 8:
6 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 153512.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 153512.0 and a remainder of 0.0.
