Let's divide 185990 by 6
The aim is to understand the frequency of 6 in 185990.

On to step 1:
1 divided by 6 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 6

Let's proceed to step 2:
6 goes into 18 3 times with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 18 from 18, we get 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 6

Step 3:
6 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 30.0
Subtract 0 from 5 to get 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 6

Let's proceed to step 4:
59 divided by 6 is 9 with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 309.0
Subtract 54 from 59 to get 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 6

Going ahead to step 5:
6 goes into 59 9 times with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 3099.0
Deduct 54 from 59 and we're left with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 6

On to step 6:
If we divide 50 by 6, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 30998.0
Subtracting 48 from 50 leaves us 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.

Moving on to step 7:
If we divide 20 by 6, we get 3 and a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 30998.3
If we subtract 18 from 20, we 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:
20 divided by 6 is 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 30998.33
Subtracting 18 from 20 leaves us 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.

The final outcome is 30998.33, with a leftover of 0.002.
