Let's divide 452471 by 90
The aim is to understand the frequency of 90 in 452471.

Moving on 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
Subtract 0 from 4 to get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 90

Moving on to step 2:
The number 90 fits into 45 0 times, leaving a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Fetch the next digit (2) from the dividend, attach it to 45 and continue: 452 / 90

Moving on to step 3:
The number 90 fits into 452 5 times, leaving a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 450 from 452 to get 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 90

Let's proceed to step 4:
90 goes into 24 0 times with a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 50.0
The remainder is 24 after subtracting 0 from 24.
Include the next digit (7) from the dividend after 24, then repeat: 247 / 90

Step 5:
If we divide 247 by 90, we get 2 and a remainder of 67.
Use 2 as the next digit of our solution. 
Result so far: 502.0
Deduct 180 from 247 and we're left with 67.
Include the next digit (1) from the dividend after 67, then repeat: 671 / 90

Moving on to step 6:
90 can be fit into 671 7 times, resulting in a remainder of 41.
Record the quotient 7 as the next digit in the result. 
Result so far: 5027.0
If we subtract 630 from 671, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 7:
90 can be fit into 410 4 times, resulting in a remainder of 50.
Use 4 as the next digit of our solution. 
Result so far: 5027.4
If we subtract 360 from 410, 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 8:
500 divided by 90 is 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 5027.45
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.

Going ahead to step 9:
When dividing 500 by 90, we get 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 5027.455
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.

The quotient of the division is 5027.455, and the remainder is 0.005.
