Let's divide 210837 by 6
The aim is to understand the frequency of 6 in 210837.

On to step 1:
When dividing 2 by 6, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 6

Advancing to step 2:
21 divided by 6 is 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 18 from 21 to get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 6

Moving on to step 3:
If we divide 30 by 6, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 35.0
The remainder is 0 after subtracting 30 from 30.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 6

Step 4:
When dividing 8 by 6, we get 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 351.0
Subtracting 6 from 8 leaves us with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 6

On to step 5:
If we divide 23 by 6, we get 3 and a remainder of 5.
The next digit of our result is 3. 
Result so far: 3513.0
If we take 18 away from 23, we end up with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 6

Step 6:
If we divide 57 by 6, we get 9 and a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 35139.0
Subtracting 54 from 57 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
If we divide 30 by 6, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 35139.5
Subtract 30 from 30 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 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 35139.5
Subtracting 0 from 0 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 9:
6 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 35139.5
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.

Our division results in 35139.5 with a remaining 0.0.
