744807 ÷ 90 
The aim is to understand the frequency of 90 in 744807.

Moving on to step 1:
90 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 90

Let's proceed to step 2:
The number 90 fits into 74 0 times, leaving a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 74, we end up with 74.
Include the next digit (4) from the dividend after 74, then repeat: 744 / 90

Moving on to step 3:
744 divided by 90 is 8 with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 720 away from 744, we end up with 24.
Fetch the next digit (8) from the dividend, attach it to 24 and continue: 248 / 90

Step 4:
248 divided by 90 is 2 with a remainder of 68.
The next digit of our result is 2. 
Result so far: 82.0
Subtract 180 from 248 to get 68.
Grab the next digit (0) from the dividend, add it to 68, then carry on: 680 / 90

Let's proceed to step 5:
The number 90 fits into 680 7 times, leaving a remainder of 50.
Use 7 as the next digit of our solution. 
Result so far: 827.0
If we subtract 630 from 680, we get 50.
Take the next digit (7) from the dividend and append it to 50, then repeat: 507 / 90

Going ahead to step 6:
90 can be fit into 507 5 times, resulting in a remainder of 57.
Use 5 as the next digit of our solution. 
Result so far: 8275.0
If we take 450 away from 507, we end up 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.

Moving on to step 7:
If we divide 570 by 90, we get 6 and a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 8275.6
The remainder is 30 after subtracting 540 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
The number 90 fits into 300 3 times, leaving a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 8275.63
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.

Step 9:
When dividing 300 by 90, we get 3 with a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 8275.633
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 8275.633, and the remainder is 0.003.
