We're dividing 967893 by 90 
The aim is to understand the frequency of 90 in 967893.

Going ahead 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
The remainder is 9 after subtracting 0 from 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 90

On to step 2:
The number 90 fits into 96 1 times, leaving a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 90 from 96 leaves us with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 90

Step 3:
67 divided by 90 is 0 with a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 67 leaves us with 67.
Take the next digit (8) from the dividend and append it to 67, then repeat: 678 / 90

Advancing to step 4:
If we divide 678 by 90, we get 7 and a remainder of 48.
Use 7 as the next digit of our solution. 
Result so far: 107.0
Subtract 630 from 678 to get 48.
Include the next digit (9) from the dividend after 48, then repeat: 489 / 90

Let's proceed to step 5:
If we divide 489 by 90, we get 5 and a remainder of 39.
The next digit of our result is 5. 
Result so far: 1075.0
Deduct 450 from 489 and we're left with 39.
Take the next digit (3) from the dividend and append it to 39, then repeat: 393 / 90

Let's proceed to step 6:
90 goes into 393 4 times with a remainder of 33.
Use 4 as the next digit of our solution. 
Result so far: 10754.0
If we subtract 360 from 393, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 7:
90 can be fit into 330 3 times, resulting in a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 10754.3
If we subtract 270 from 330, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 8:
90 can be fit into 600 6 times, resulting in a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 10754.36
The remainder is 60 after subtracting 540 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 9:
90 can be fit into 600 6 times, resulting in a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 10754.366
If we subtract 540 from 600, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final outcome is 10754.366, with a leftover of 0.006.
