Let's divide 606027 by 90
The aim is to understand the frequency of 90 in 606027.

Step 1:
The number 90 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 90

On to step 2:
90 can be fit into 60 0 times, resulting in a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 60, we get 60.
Bring next digit (6) of the dividend behind the 60 and repeat the process: 606 / 90

On to step 3:
606 divided by 90 is 6 with a remainder of 66.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 540 from 606 leaves us with 66.
Take the next digit (0) from the dividend and append it to 66, then repeat: 660 / 90

Advancing to step 4:
90 goes into 660 7 times with a remainder of 30.
Put 7 as the next digit of the answer. 
Result so far: 67.0
The remainder is 30 after subtracting 630 from 660.
Bring next digit (2) of the dividend behind the 30 and repeat the process: 302 / 90

Step 5:
302 divided by 90 is 3 with a remainder of 32.
Write down 3 as next digit of the result. 
Result so far: 673.0
The remainder is 32 after subtracting 270 from 302.
Bring next digit (7) of the dividend behind the 32 and repeat the process: 327 / 90

Let's proceed to step 6:
90 goes into 327 3 times with a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 6733.0
If we take 270 away from 327, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 7:
90 can be fit into 570 6 times, resulting in a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 6733.6
If we subtract 540 from 570, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
When dividing 300 by 90, we get 3 with a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 6733.63
If we take 270 away from 300, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
300 divided by 90 is 3 with a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 6733.633
Subtracting 270 from 300 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 6733.633 with a remainder of 0.003.
