Let's divide 555974 by 6
The aim is to understand the frequency of 6 in 555974.

Step 1:
6 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 6

Moving on to step 2:
6 goes into 55 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 54 from 55 to get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 6

Let's proceed to step 3:
6 goes into 15 2 times with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 92.0
The remainder is 3 after subtracting 12 from 15.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 6

Advancing to step 4:
If we divide 39 by 6, we get 6 and a remainder of 3.
The next digit of our result is 6. 
Result so far: 926.0
Deduct 36 from 39 and we're left with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 6

Going ahead to step 5:
If we divide 37 by 6, we get 6 and a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 9266.0
The remainder is 1 after subtracting 36 from 37.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 6

Moving on to step 6:
The number 6 fits into 14 2 times, leaving a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 92662.0
Deduct 12 from 14 and we're left 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.

Advancing to step 7:
The number 6 fits into 20 3 times, leaving a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 92662.3
Subtract 18 from 20 to 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.

On to step 8:
If we divide 20 by 6, we get 3 and a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 92662.33
Subtract 18 from 20 to 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.

The final outcome is 92662.33, with a leftover of 0.002.
