We're dividing 476672 by 90 
The aim is to understand the frequency of 90 in 476672.

Moving on to step 1:
90 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 90

Moving on to step 2:
90 can be fit into 47 0 times, resulting in a remainder of 47.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 47 to get 47.
Take the next digit (6) from the dividend and append it to 47, then repeat: 476 / 90

Going ahead to step 3:
When dividing 476 by 90, we get 5 with a remainder of 26.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 450 from 476 leaves us with 26.
Include the next digit (6) from the dividend after 26, then repeat: 266 / 90

Going ahead to step 4:
If we divide 266 by 90, we get 2 and a remainder of 86.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
Deduct 180 from 266 and we're left with 86.
Bring next digit (7) of the dividend behind the 86 and repeat the process: 867 / 90

On to step 5:
90 can be fit into 867 9 times, resulting in a remainder of 57.
The number 9 becomes the next digit in our result. 
Result so far: 529.0
Deduct 810 from 867 and we're left with 57.
Take the next digit (2) from the dividend and append it to 57, then repeat: 572 / 90

Going ahead to step 6:
90 can be fit into 572 6 times, resulting in a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 5296.0
The remainder is 32 after subtracting 540 from 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 7:
If we divide 320 by 90, we get 3 and a remainder of 50.
Record the quotient 3 as the next digit in the result. 
Result so far: 5296.3
Subtract 270 from 320 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
When dividing 500 by 90, we get 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 5296.35
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 9:
90 goes into 500 5 times with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 5296.355
Deduct 450 from 500 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 5296.355 with a remainder of 0.005.
