We divide 444611 by 90
The aim is to understand the frequency of 90 in 444611.

Going ahead to step 1:
90 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 90

Step 2:
If we divide 44 by 90, we get 0 and a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 44 after subtracting 0 from 44.
Append the next digit (4) from the dividend to 44 and continue with: 444 / 90

Moving on to step 3:
90 goes into 444 4 times with a remainder of 84.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 84 after subtracting 360 from 444.
Bring next digit (6) of the dividend behind the 84 and repeat the process: 846 / 90

Going ahead to step 4:
The number 90 fits into 846 9 times, leaving a remainder of 36.
Put 9 as the next digit of the answer. 
Result so far: 49.0
If we subtract 810 from 846, we get 36.
Include the next digit (1) from the dividend after 36, then repeat: 361 / 90

Step 5:
If we divide 361 by 90, we get 4 and a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 494.0
If we take 360 away from 361, we end up with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 90

Step 6:
11 divided by 90 is 0 with a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 4940.0
If we take 0 away from 11, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
If we divide 110 by 90, we get 1 and a remainder of 20.
The next digit of our result is 1. 
Result so far: 4940.1
If we take 90 away from 110, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
If we divide 200 by 90, we get 2 and a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 4940.12
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
When dividing 200 by 90, we get 2 with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 4940.122
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 4940.122 with a remaining 0.002.
