446106 ÷ 90 
The aim is to understand the frequency of 90 in 446106.

Let's proceed to step 1:
If we divide 4 by 90, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 90

Advancing to step 2:
90 goes into 44 0 times with a remainder of 44.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 44 leaves us with 44.
Include the next digit (6) from the dividend after 44, then repeat: 446 / 90

Going ahead to step 3:
90 can be fit into 446 4 times, resulting in a remainder of 86.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 360 from 446, we get 86.
Append the next digit (1) from the dividend to 86 and continue with: 861 / 90

Step 4:
90 can be fit into 861 9 times, resulting in a remainder of 51.
The next digit of our result is 9. 
Result so far: 49.0
The remainder is 51 after subtracting 810 from 861.
Grab the next digit (0) from the dividend, add it to 51, then carry on: 510 / 90

On to step 5:
510 divided by 90 is 5 with a remainder of 60.
The next digit of our result is 5. 
Result so far: 495.0
The remainder is 60 after subtracting 450 from 510.
Fetch the next digit (6) from the dividend, attach it to 60 and continue: 606 / 90

Moving on to step 6:
606 divided by 90 is 6 with a remainder of 66.
The next digit of our result is 6. 
Result so far: 4956.0
Subtracting 540 from 606 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 7:
If we divide 660 by 90, we get 7 and a remainder of 30.
Use 7 as the next digit of our solution. 
Result so far: 4956.7
Subtract 630 from 660 to 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.

Step 8:
90 goes into 300 3 times with a remainder of 30.
The next digit of our result is 3. 
Result so far: 4956.73
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.

On to step 9:
90 goes into 300 3 times with a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 4956.733
The remainder is 30 after subtracting 270 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 4956.733 and a remainder of 0.003.
