We look at the division of 510926 by 6 
The aim is to understand the frequency of 6 in 510926.

Let's proceed to step 1:
When dividing 5 by 6, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 6

Step 2:
6 goes into 51 8 times with a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 48 from 51, we get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 6

Going ahead to step 3:
The number 6 fits into 30 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 85.0
The remainder is 0 after subtracting 30 from 30.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 6

Step 4:
9 divided by 6 is 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 851.0
Subtracting 6 from 9 leaves us with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 6

Advancing to step 5:
If we divide 32 by 6, we get 5 and a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 8515.0
Subtracting 30 from 32 leaves us with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 6

Step 6:
6 can be fit into 26 4 times, resulting in a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 85154.0
Deduct 24 from 26 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
If we divide 20 by 6, we get 3 and a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 85154.3
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
If we divide 20 by 6, we get 3 and a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 85154.33
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 85154.33, and the remainder is 0.002.
