We look at the division of 90229453 by 6 
The aim is to understand the frequency of 6 in 90229453.

Let's proceed to step 1:
The number 6 fits into 9 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 6 from 9 leaves us with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 6

Going ahead to step 2:
6 goes into 30 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtracting 30 from 30 leaves us with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 6

Advancing to step 3:
When dividing 2 by 6, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 150.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 6

Step 4:
When dividing 22 by 6, we get 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 1503.0
If we take 18 away from 22, we end up with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 6

Step 5:
The number 6 fits into 49 8 times, leaving a remainder of 1.
The next digit of our result is 8. 
Result so far: 15038.0
The remainder is 1 after subtracting 48 from 49.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 6

Going ahead 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: 150382.0
Subtract 12 from 14 to get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 6

Let's proceed to step 7:
If we divide 25 by 6, we get 4 and a remainder of 1.
The next digit of our result is 4. 
Result so far: 1503824.0
If we subtract 24 from 25, we get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 6

Moving on to step 8:
13 divided by 6 is 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 15038242.0
The remainder is 1 after subtracting 12 from 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
6 goes into 10 1 times with a remainder of 4.
The next digit of our result is 1. 
Result so far: 15038242.1
The remainder is 4 after subtracting 6 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
6 can be fit into 40 6 times, resulting in a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 15038242.16
If we take 36 away from 40, 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.

On to step 11:
6 goes into 40 6 times with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 15038242.166
If we take 36 away from 40, 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.

In conclusion, the division gives 15038242.166 with a balance of 0.0004.
