We're dividing 90789 by 93 
The aim is to understand the frequency of 93 in 90789.

Let's proceed to step 1:
If we divide 9 by 93, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 93

Step 2:
If we divide 90 by 93, we get 0 and a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Take the next digit (7) from the dividend and append it to 90, then repeat: 907 / 93

On to step 3:
The number 93 fits into 907 9 times, leaving a remainder of 70.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 837 from 907 and we're left with 70.
Take the next digit (8) from the dividend and append it to 70, then repeat: 708 / 93

Moving on to step 4:
708 divided by 93 is 7 with a remainder of 57.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
Deduct 651 from 708 and we're left with 57.
Take the next digit (9) from the dividend and append it to 57, then repeat: 579 / 93

Step 5:
93 can be fit into 579 6 times, resulting in a remainder of 21.
Use 6 as the next digit of our solution. 
Result so far: 976.0
Deduct 558 from 579 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 6:
210 divided by 93 is 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 976.2
The remainder is 24 after subtracting 186 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 7:
If we divide 240 by 93, we get 2 and a remainder of 54.
Write down 2 as next digit of the result. 
Result so far: 976.22
Deduct 186 from 240 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Our division results in 976.22 with a remaining 0.054.
