262947 ÷ 90 
The aim is to understand the frequency of 90 in 262947.

Step 1:
The number 90 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 90

Moving on to step 2:
26 divided by 90 is 0 with a remainder of 26.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 26 after subtracting 0 from 26.
Fetch the next digit (2) from the dividend, attach it to 26 and continue: 262 / 90

On to step 3:
90 goes into 262 2 times with a remainder of 82.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 180 away from 262, we end up with 82.
Grab the next digit (9) from the dividend, add it to 82, then carry on: 829 / 90

On to step 4:
When dividing 829 by 90, we get 9 with a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 29.0
Subtracting 810 from 829 leaves us with 19.
Include the next digit (4) from the dividend after 19, then repeat: 194 / 90

Let's proceed to step 5:
194 divided by 90 is 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 292.0
Subtracting 180 from 194 leaves us with 14.
Include the next digit (7) from the dividend after 14, then repeat: 147 / 90

On to step 6:
90 can be fit into 147 1 times, resulting in a remainder of 57.
Write down 1 as next digit of the result. 
Result so far: 2921.0
Subtracting 90 from 147 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 7:
90 goes into 570 6 times with a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 2921.6
If we take 540 away from 570, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
90 can be fit into 300 3 times, resulting in a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 2921.63
If we subtract 270 from 300, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
If we divide 300 by 90, we get 3 and a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 2921.633
Subtract 270 from 300 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 2921.633, and the remainder is 0.003.
