We look at the division of 918973 by 6 
The aim is to understand the frequency of 6 in 918973.

Advancing to step 1:
6 goes into 9 1 times with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 6 from 9, we get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 6

Advancing to step 2:
The number 6 fits into 31 5 times, leaving a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
The remainder is 1 after subtracting 30 from 31.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 6

Advancing to step 3:
When dividing 18 by 6, we get 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 153.0
Subtracting 18 from 18 leaves us with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 6

On to step 4:
9 divided by 6 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1531.0
The remainder is 3 after subtracting 6 from 9.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 6

Advancing to step 5:
If we divide 37 by 6, we get 6 and a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 15316.0
Subtracting 36 from 37 leaves us with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 6

Going ahead to step 6:
13 divided by 6 is 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 153162.0
If we subtract 12 from 13, 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:
If we divide 10 by 6, we get 1 and a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 153162.1
The remainder is 4 after subtracting 6 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
When dividing 40 by 6, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 153162.16
Subtracting 36 from 40 leaves us 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:
The number 6 fits into 40 6 times, leaving a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 153162.166
Deduct 36 from 40 and we're left 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.

The quotient of the division is 153162.166, and the remainder is 0.0004.
