Let's divide 108473 by 90
The aim is to understand the frequency of 90 in 108473.

Step 1:
90 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 90

Moving on to step 2:
10 divided by 90 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 90

On to step 3:
108 divided by 90 is 1 with a remainder of 18.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 90 from 108 to get 18.
Append the next digit (4) from the dividend to 18 and continue with: 184 / 90

On to step 4:
90 can be fit into 184 2 times, resulting in a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 180 from 184 leaves us with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 90

Moving on to step 5:
90 goes into 47 0 times with a remainder of 47.
Put 0 as the next digit of the answer. 
Result so far: 120.0
Deduct 0 from 47 and we're left with 47.
Append the next digit (3) from the dividend to 47 and continue with: 473 / 90

Moving on to step 6:
The number 90 fits into 473 5 times, leaving a remainder of 23.
The next digit of our result is 5. 
Result so far: 1205.0
Deduct 450 from 473 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 7:
90 goes into 230 2 times with a remainder of 50.
The next digit of our result is 2. 
Result so far: 1205.2
Subtracting 180 from 230 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
When dividing 500 by 90, we get 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 1205.25
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 9:
500 divided by 90 is 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 1205.255
The remainder is 50 after subtracting 450 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 1205.255, and the remainder is 0.005.
