We divide 9425 by 6
The aim is to understand the frequency of 6 in 9425.

On to step 1:
9 divided by 6 is 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 6 from 9 and we're left with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 6

On to step 2:
When dividing 34 by 6, we get 5 with a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtracting 30 from 34 leaves us with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 6

Step 3:
When dividing 42 by 6, we get 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 157.0
Deduct 42 from 42 and we're left with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 6

On to step 4:
5 divided by 6 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 1570.0
Subtracting 0 from 5 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 5:
If we divide 50 by 6, we get 8 and a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 1570.8
If we take 48 away from 50, we end up 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 6:
If we divide 20 by 6, we get 3 and a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 1570.83
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead 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: 1570.833
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 result is 1570.833 with a remainder of 0.0002.
