959031 ÷ 90 
The aim is to understand the frequency of 90 in 959031.

Let's proceed to step 1:
When dividing 9 by 90, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 90

Going ahead to step 2:
If we divide 95 by 90, we get 1 and a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 90 from 95 leaves us with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 90

Step 3:
If we divide 59 by 90, we get 0 and a remainder of 59.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 59 to get 59.
Bring next digit (0) of the dividend behind the 59 and repeat the process: 590 / 90

Moving on to step 4:
When dividing 590 by 90, we get 6 with a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 106.0
If we subtract 540 from 590, we get 50.
Append the next digit (3) from the dividend to 50 and continue with: 503 / 90

Let's proceed to step 5:
90 can be fit into 503 5 times, resulting in a remainder of 53.
The next digit of our result is 5. 
Result so far: 1065.0
If we subtract 450 from 503, we get 53.
Bring next digit (1) of the dividend behind the 53 and repeat the process: 531 / 90

Step 6:
90 goes into 531 5 times with a remainder of 81.
The number 5 becomes the next digit in our result. 
Result so far: 10655.0
If we take 450 away from 531, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 7:
90 can be fit into 810 9 times, resulting in a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 10655.9
The remainder is 0 after subtracting 810 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
0 divided by 90 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10655.9
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
0 divided by 90 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10655.9
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 10655.9, and the remainder is 0.0.
