195039 ÷ 90 
The aim is to understand the frequency of 90 in 195039.

On to step 1:
1 divided by 90 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 90

Step 2:
If we divide 19 by 90, we get 0 and a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Fetch the next digit (5) from the dividend, attach it to 19 and continue: 195 / 90

Let's proceed to step 3:
90 goes into 195 2 times with a remainder of 15.
The next digit of our result is 2. 
Result so far: 2.0
If we take 180 away from 195, we end up with 15.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 90

Going ahead to step 4:
When dividing 150 by 90, we get 1 with a remainder of 60.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we take 90 away from 150, we end up with 60.
Fetch the next digit (3) from the dividend, attach it to 60 and continue: 603 / 90

Moving on to step 5:
90 can be fit into 603 6 times, resulting in a remainder of 63.
Put 6 as the next digit of the answer. 
Result so far: 216.0
Subtract 540 from 603 to get 63.
Fetch the next digit (9) from the dividend, attach it to 63 and continue: 639 / 90

Let's proceed to step 6:
If we divide 639 by 90, we get 7 and a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 2167.0
If we subtract 630 from 639, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
90 goes into 90 1 times with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 2167.1
Subtracting 90 from 90 leaves us 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.

Moving on to step 8:
90 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2167.1
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
The number 90 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2167.1
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 2167.1, and the remainder is 0.0.
