249726 ÷ 90 
The aim is to understand the frequency of 90 in 249726.

Let's proceed to step 1:
90 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 90

Advancing to step 2:
24 divided by 90 is 0 with a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 24, we get 24.
Grab the next digit (9) from the dividend, add it to 24, then carry on: 249 / 90

Step 3:
90 goes into 249 2 times with a remainder of 69.
The next digit of our result is 2. 
Result so far: 2.0
If we take 180 away from 249, we end up with 69.
Grab the next digit (7) from the dividend, add it to 69, then carry on: 697 / 90

Going ahead to step 4:
697 divided by 90 is 7 with a remainder of 67.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
The remainder is 67 after subtracting 630 from 697.
Include the next digit (2) from the dividend after 67, then repeat: 672 / 90

Going ahead to step 5:
The number 90 fits into 672 7 times, leaving a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 277.0
If we take 630 away from 672, we end up with 42.
Take the next digit (6) from the dividend and append it to 42, then repeat: 426 / 90

Let's proceed to step 6:
The number 90 fits into 426 4 times, leaving a remainder of 66.
The next digit of our result is 4. 
Result so far: 2774.0
If we subtract 360 from 426, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 7:
90 goes into 660 7 times with a remainder of 30.
Write down 7 as next digit of the result. 
Result so far: 2774.7
Deduct 630 from 660 and we're left 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.

Advancing to step 8:
If we divide 300 by 90, we get 3 and a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 2774.73
Subtracting 270 from 300 leaves us 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 9:
If we divide 300 by 90, we get 3 and a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 2774.733
If we take 270 away from 300, 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.

The quotient of the division is 2774.733, and the remainder is 0.003.
