We look at the division of 921993 by 6 
The aim is to understand the frequency of 6 in 921993.

Advancing to step 1:
If we divide 9 by 6, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 6 from 9 and we're left with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 6

Advancing to step 2:
When dividing 32 by 6, we get 5 with a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we take 30 away from 32, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 6

Going ahead to step 3:
21 divided by 6 is 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 153.0
Subtracting 18 from 21 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 6

Going ahead to step 4:
The number 6 fits into 39 6 times, leaving a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 1536.0
Deduct 36 from 39 and we're left with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 6

On to step 5:
When dividing 39 by 6, we get 6 with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 15366.0
Deduct 36 from 39 and we're left with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 6

Step 6:
33 divided by 6 is 5 with a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 153665.0
The remainder is 3 after subtracting 30 from 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
When dividing 30 by 6, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 153665.5
Subtracting 30 from 30 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.

Going ahead to step 8:
0 divided by 6 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 153665.5
The remainder is 0 after subtracting 0 from 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 9:
When dividing 0 by 6, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 153665.5
If we subtract 0 from 0, we 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.

The quotient of the division is 153665.5, and the remainder is 0.0.
