We look at the division of 754738 by 6 
The aim is to understand the frequency of 6 in 754738.

Let's proceed to step 1:
If we divide 7 by 6, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 6 from 7 leaves us with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 6

Going ahead to step 2:
If we divide 15 by 6, we get 2 and a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 3 after subtracting 12 from 15.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 6

Going ahead to step 3:
If we divide 34 by 6, we get 5 and a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
Subtract 30 from 34 to get 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 6

Moving on to step 4:
When dividing 47 by 6, we get 7 with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 1257.0
The remainder is 5 after subtracting 42 from 47.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 6

Moving on to step 5:
6 goes into 53 8 times with a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 12578.0
If we subtract 48 from 53, we get 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 6

Moving on to step 6:
6 goes into 58 9 times with a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 125789.0
If we take 54 away from 58, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
If we divide 40 by 6, we get 6 and a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 125789.6
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
When dividing 40 by 6, we get 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 125789.66
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 125789.66 with a remainder of 0.004.
