189951 ÷ 6 
The aim is to understand the frequency of 6 in 189951.

Let's proceed to step 1:
When dividing 1 by 6, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 6

Moving on to step 2:
6 can be fit into 18 3 times, resulting in a remainder of 0.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 18 from 18 and we're left with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 6

On to step 3:
9 divided by 6 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Subtract 6 from 9 to get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 6

Step 4:
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: 316.0
Subtracting 36 from 39 leaves us with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 6

Advancing to step 5:
If we divide 35 by 6, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 3165.0
The remainder is 5 after subtracting 30 from 35.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 6

Moving on to step 6:
51 divided by 6 is 8 with a remainder of 3.
The next digit of our result is 8. 
Result so far: 31658.0
Deduct 48 from 51 and we're left 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.

Moving on to step 7:
If we divide 30 by 6, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 31658.5
Deduct 30 from 30 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.

Advancing to step 8:
The number 6 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 31658.5
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.

Advancing to step 9:
6 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 31658.5
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.

The final outcome is 31658.5, with a leftover of 0.0.
