We look at the division of 950444 by 90 
The aim is to understand the frequency of 90 in 950444.

Advancing to step 1:
When dividing 9 by 90, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 90

Advancing to step 2:
The number 90 fits into 95 1 times, leaving a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 90 away from 95, we end up with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 90

Moving on to step 3:
90 can be fit into 50 0 times, resulting in a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 50, we end up with 50.
Append the next digit (4) from the dividend to 50 and continue with: 504 / 90

Advancing to step 4:
When dividing 504 by 90, we get 5 with a remainder of 54.
The next digit of our result is 5. 
Result so far: 105.0
If we take 450 away from 504, we end up with 54.
Grab the next digit (4) from the dividend, add it to 54, then carry on: 544 / 90

Moving on to step 5:
90 can be fit into 544 6 times, resulting in a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 1056.0
If we subtract 540 from 544, we get 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 90

Going ahead to step 6:
When dividing 44 by 90, we get 0 with a remainder of 44.
Write down 0 as next digit of the result. 
Result so far: 10560.0
Subtracting 0 from 44 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 7:
If we divide 440 by 90, we get 4 and a remainder of 80.
Record the quotient 4 as the next digit in the result. 
Result so far: 10560.4
Subtract 360 from 440 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 8:
When dividing 800 by 90, we get 8 with a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 10560.48
If we take 720 away from 800, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 9:
90 can be fit into 800 8 times, resulting in a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 10560.488
If we take 720 away from 800, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The quotient of the division is 10560.488, and the remainder is 0.008.
