We look at the division of 813120 by 6 
The aim is to understand the frequency of 6 in 813120.

Going ahead to step 1:
6 goes into 8 1 times with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 6 from 8 to get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 6

Moving on to step 2:
When dividing 21 by 6, we get 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 13.0
The remainder is 3 after subtracting 18 from 21.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 6

Going ahead to step 3:
33 divided by 6 is 5 with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 135.0
Subtracting 30 from 33 leaves us with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 6

Step 4:
When dividing 31 by 6, we get 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 1355.0
Deduct 30 from 31 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 6

Moving on to step 5:
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: 13552.0
Subtracting 12 from 12 leaves us with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 6

Advancing to step 6:
6 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 135520.0
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.

Moving on to step 7:
0 divided by 6 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 135520.0
If we take 0 away from 0, we end up 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.

Going ahead to step 8:
The number 6 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 135520.0
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 quotient of the division is 135520.0, and the remainder is 0.0.
