Let's divide 96766 by 90
The aim is to understand the frequency of 90 in 96766.

Advancing to step 1:
9 divided by 90 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 90

Going ahead to step 2:
When dividing 96 by 90, we get 1 with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 90 from 96 to get 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 90

On to step 3:
90 goes into 67 0 times with a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 67 to get 67.
Take the next digit (6) from the dividend and append it to 67, then repeat: 676 / 90

Let's proceed to step 4:
90 goes into 676 7 times with a remainder of 46.
Record the quotient 7 as the next digit in the result. 
Result so far: 107.0
Subtract 630 from 676 to get 46.
Include the next digit (6) from the dividend after 46, then repeat: 466 / 90

Let's proceed to step 5:
If we divide 466 by 90, we get 5 and a remainder of 16.
Write down 5 as next digit of the result. 
Result so far: 1075.0
Subtracting 450 from 466 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 6:
90 goes into 160 1 times with a remainder of 70.
The next digit of our result is 1. 
Result so far: 1075.1
The remainder is 70 after subtracting 90 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 7:
The number 90 fits into 700 7 times, leaving a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 1075.17
Deduct 630 from 700 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 8:
If we divide 700 by 90, we get 7 and a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 1075.177
If we subtract 630 from 700, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 1075.177 with a remaining 0.007.
