Let's divide 965358 by 90
The aim is to understand the frequency of 90 in 965358.

Advancing to step 1:
90 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 90

Step 2:
90 goes into 96 1 times with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 90 from 96, we get 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 90

Advancing to step 3:
The number 90 fits into 65 0 times, leaving a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 65 to get 65.
Include the next digit (3) from the dividend after 65, then repeat: 653 / 90

Step 4:
If we divide 653 by 90, we get 7 and a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 107.0
If we take 630 away from 653, we end up with 23.
Include the next digit (5) from the dividend after 23, then repeat: 235 / 90

Going ahead to step 5:
90 goes into 235 2 times with a remainder of 55.
The next digit of our result is 2. 
Result so far: 1072.0
Subtracting 180 from 235 leaves us with 55.
Include the next digit (8) from the dividend after 55, then repeat: 558 / 90

Moving on to step 6:
When dividing 558 by 90, we get 6 with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 10726.0
Subtracting 540 from 558 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 7:
If we divide 180 by 90, we get 2 and a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 10726.2
The remainder is 0 after subtracting 180 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
0 divided by 90 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10726.2
If we take 0 away from 0, we end up with 0.
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 9:
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: 10726.2
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 10726.2 and a remainder of 0.0.
