Let's divide 470560 by 90
The aim is to understand the frequency of 90 in 470560.

Advancing to step 1:
90 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 90

On to step 2:
The number 90 fits into 47 0 times, leaving a remainder of 47.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 47 and we're left with 47.
Append the next digit (0) from the dividend to 47 and continue with: 470 / 90

Moving on to step 3:
90 can be fit into 470 5 times, resulting in a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 450 from 470 leaves us with 20.
Fetch the next digit (5) from the dividend, attach it to 20 and continue: 205 / 90

Let's proceed to step 4:
90 goes into 205 2 times with a remainder of 25.
Put 2 as the next digit of the answer. 
Result so far: 52.0
The remainder is 25 after subtracting 180 from 205.
Take the next digit (6) from the dividend and append it to 25, then repeat: 256 / 90

On to step 5:
90 can be fit into 256 2 times, resulting in a remainder of 76.
Record the quotient 2 as the next digit in the result. 
Result so far: 522.0
The remainder is 76 after subtracting 180 from 256.
Take the next digit (0) from the dividend and append it to 76, then repeat: 760 / 90

Step 6:
The number 90 fits into 760 8 times, leaving a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 5228.0
Deduct 720 from 760 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 7:
When dividing 400 by 90, we get 4 with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 5228.4
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
The number 90 fits into 400 4 times, leaving a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 5228.44
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 5228.44, with a leftover of 0.04.
